Question 1

Amir has data: salt water 97% and fresh water 3%; which graph best shows this distribution?

  1. Line graph to show change over time
  2. Pie chart with two percentage slices (correct answer)
  3. Scatter plot with two variables
  4. 3D surface graph with shading
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2). Different types of data require different types of graphs; water distribution data shows parts of a whole (percentages that add to 100%), making pie charts (circle graphs) ideal because each slice's size shows its proportion of the total, while bar graphs also work well for comparing the amounts in different reservoirs, with bar height representing percentage, but line graphs would be inappropriate because they show change over time, not categorical data (different categories being compared at one time); key graph components include: clear title, labeled sections or axes, percentage values shown, and legend if using colors. Choice B is correct because a pie chart with two percentage slices is appropriate for showing parts of a whole, which matches the data type, and a well-made graph must include title ('Distribution of Water on Earth'), labels (salt water, fresh water), and percentages (97%, 3%), demonstrating understanding that graph type should match data characteristics and that complete graphs include all necessary components for interpretation. Choice A is incorrect because line graphs show change over time, not categorical comparisons; this error commonly occurs when students don't understand that different graph types serve different purposes, when they choose graphs they're most familiar with regardless of appropriateness, or when they create graphs without essential components like titles and labels; students may also not recognize that line graphs require sequential data (like time) while this data is categorical. To help students: Teach decision tree for graph selection: (1) Is it parts of a whole adding to 100%? → Pie chart. (2) Comparing amounts across categories? → Bar graph. (3) Showing change over time? → Line graph. (4) Showing relationship between two variables? → Scatter plot; practice with water distribution data: Give students the percentages and have them create both a pie chart and bar graph to see both work; emphasize essential components checklist: Title? Labels? Values shown? Appropriate type? Use graph paper or digital tools. Model: 'The data shows percentages of total water, so we need to show parts of whole - pie chart is perfect'; watch for: students who always use the same graph type regardless of data, who forget labels and titles, who can't explain why their choice is appropriate, or who use line graphs for categorical data; explicitly teach: Line graphs are for change over time (temperature each day), not for comparing categories (water in different places).

Question 2

Keisha lists oceans 97%, lakes 0.01%, rivers 0.0001%; which display is most visual?

  1. Pie chart (circle graph) with labeled slices (correct answer)
  2. Write the numbers in a sentence
  3. Scatter plot with x and y variables
  4. Line graph to show a trend
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2). When data shows extreme differences in scale (oceans 97%, lakes 0.01%, rivers 0.0001%), visual representations become crucial for understanding. Pie charts provide the most visual display by using slice sizes to show proportions - the ocean slice would dominate while lakes and rivers would be barely visible slivers, immediately communicating the vast scale differences. Written sentences lack visual impact, while scatter plots and line graphs are inappropriate for this categorical data type. Choice A is correct because pie charts with labeled slices provide the most visual representation of these extreme proportions. The ocean slice at 97% would fill almost the entire circle, making the tiny freshwater percentages visually apparent as hair-thin slices. This demonstrates understanding that visual displays can communicate scale differences more powerfully than numbers alone. Choice B is incorrect because writing numbers in sentences provides no visual representation. Choice C is incorrect because scatter plots require two related variables, not categories with single values. Choice D is incorrect because line graphs show trends over time, not categorical comparisons. These errors commonly occur when students don't appreciate how visual representations enhance understanding of extreme scale differences or when they choose graphs based on familiarity rather than appropriateness. To help students: Teach the power of visual representation for extreme scales: Draw a pie chart showing these values to demonstrate how the 0.01% and 0.0001% slices are barely visible. Discuss why this visual impact matters for understanding Earth's water scarcity. Practice with scale: 'If the whole circle is your allowance, the ocean slice is $97, lakes are 1 penny, and rivers are 1/100th of a penny!' Model: 'These numbers are hard to grasp, but a pie chart makes the extreme differences visible instantly.' Watch for: students who don't recognize when visual representation adds value beyond numbers, who struggle with very small percentages, or who don't understand that 'most visual' means creating maximum visual impact for understanding.

Question 3

Which circle graph title best matches data: oceans 97%, ice 2%, groundwater 0.6%, other 0.4%?

  1. Distribution of Water on Earth (correct answer)
  2. Daily Rainfall Over One Week
  3. Plant Growth Over Time
  4. Speed and Distance Relationship
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2). Different types of data require different types of graphs; water distribution data shows parts of a whole (percentages that add to 100%), making pie charts (circle graphs) ideal because each slice's size shows its proportion of the total, while bar graphs also work well for comparing the amounts in different reservoirs, with bar height representing percentage, but line graphs would be inappropriate because they show change over time, not categorical data (different categories being compared at one time); key graph components include: clear title, labeled sections or axes, percentage values shown, and legend if using colors. Choice A is correct because 'Distribution of Water on Earth' is an appropriate title that matches the data type, demonstrating understanding that graph type should match data characteristics and that complete graphs include all necessary components for interpretation. Choice B is incorrect because 'Daily Rainfall Over One Week' implies time-based data, not categorical percentages; this error commonly occurs when students don't understand that different graph types serve different purposes, when they choose graphs they're most familiar with regardless of appropriateness, or when they create graphs without essential components like titles and labels; students may also not recognize that line graphs require sequential data (like time) while this data is categorical. To help students: Teach decision tree for graph selection: (1) Is it parts of a whole adding to 100%? → Pie chart. (2) Comparing amounts across categories? → Bar graph. (3) Showing change over time? → Line graph. (4) Showing relationship between two variables? → Scatter plot; practice with water distribution data: Give students the percentages and have them create both a pie chart and bar graph to see both work; emphasize essential components checklist: Title? Labels? Values shown? Appropriate type? Use graph paper or digital tools. Model: 'The data shows percentages of total water, so we need to show parts of whole - pie chart is perfect'; watch for: students who always use the same graph type regardless of data, who forget labels and titles, who can't explain why their choice is appropriate, or who use line graphs for categorical data; explicitly teach: Line graphs are for change over time (temperature each day), not for comparing categories (water in different places).

Question 4

Maya wants to show oceans 97% and all fresh water 3%; which graph fits best?

  1. Line graph with time on the x-axis
  2. Pie chart (circle graph) showing 97% and 3% (correct answer)
  3. Scatter plot with dots for each category
  4. Picture graph using photos only
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2). Different types of data require different types of graphs. Water distribution data shows parts of a whole (percentages that add to 100%), making pie charts (circle graphs) ideal because each slice's size shows its proportion of the total. When showing just two categories that together make 100% (oceans 97% and fresh water 3%), a pie chart clearly displays this complementary relationship. Line graphs would be inappropriate because they show change over time, but water distribution is categorical data, not a time series. Key graph components include: clear title, labeled sections, and percentage values shown. Choice B is correct because a pie chart showing 97% and 3% perfectly represents the two parts that make up the whole of Earth's water. The large slice (97%) visually demonstrates ocean dominance, while the small slice (3%) shows the tiny fraction of fresh water. This demonstrates understanding that graph type should match data characteristics and that pie charts excel at showing proportional relationships. Choice A is incorrect because line graphs require time-based data, not categorical comparisons. Choice C is incorrect because scatter plots show relationships between two variables, not parts of a whole. Choice D is incorrect because it lacks numerical data representation. These errors commonly occur when students don't understand that different graph types serve different purposes or when they rely only on visual elements without quantitative information. To help students: Teach decision tree for graph selection: (1) Is it parts of a whole adding to 100%? → Pie chart. (2) Comparing amounts across categories? → Bar graph. (3) Showing change over time? → Line graph. Practice with simplified data: Start with just two categories (like oceans vs. fresh water) before adding more detail. Emphasize that 97% + 3% = 100%, reinforcing the 'parts of whole' concept. Model: 'We have two parts that add to 100%, so a pie chart shows this relationship perfectly.' Watch for: students who think pie charts can only be used with many categories, who forget to verify percentages add to 100%, or who choose graphs based on visual preference rather than data type.

Question 5

Maya graphs oceans 97%, ice 2%, groundwater 0.6%, lakes 0.01%; which chart fits?

  1. Use a pie chart with labeled slices and percentages (correct answer)
  2. Use a line graph because the data is in order
  3. Use a scatter plot to show a relationship
  4. Use a pie chart but leave off labels and title
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2). Different types of data require different types of graphs; water distribution data shows parts of a whole (percentages that add to 100%), making pie charts (circle graphs) ideal because each slice's size shows its proportion of the total, while bar graphs also work well for comparing the amounts in different reservoirs, with bar height representing percentage, but line graphs would be inappropriate because they show change over time, not categorical data (different categories being compared at one time); key graph components include: clear title, labeled sections or axes, percentage values shown, and legend if using colors. Choice A is correct because a pie chart with labeled slices and percentages is appropriate for showing parts of the whole, which matches the data type, and including labels and title ensures the graph is complete and interpretable. Choice B is incorrect because a line graph is for showing trends over time, not ordered categories without a time element; this error commonly occurs when students misapply graph types based on familiarity or misunderstand that categorical data doesn't imply a sequence like time. To help students: Teach decision tree for graph selection: (1) Is it parts of a whole adding to 100%? → Pie chart. (2) Comparing amounts across categories? → Bar graph. (3) Showing change over time? → Line graph. (4) Showing relationship between two variables? → Scatter plot. Practice with water distribution data: Give students the percentages and have them create both a pie chart and bar graph to see both work; emphasize essential components checklist: Title? Labels? Values shown? Appropriate type? Use graph paper or digital tools; model: 'The data shows percentages of total water, so we need to show parts of whole - pie chart is perfect.' Watch for: students who always use the same graph type regardless of data, who forget labels and titles, who can't explain why their choice is appropriate, or who use line graphs for categorical data; explicitly teach: Line graphs are for change over time (temperature each day), not for comparing categories (water in different places).

Question 6

Maya wants to represent oceans 97%, ice 2%, groundwater 0.6% as parts of a whole.

  1. Pie chart with labeled percentage sections (correct answer)
  2. Line graph showing change over time
  3. Scatter plot comparing two measurements
  4. Picture graph using photos only
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2). Different types of data require different types of graphs; water distribution data shows parts of a whole (percentages that add to 100%), making pie charts (circle graphs) ideal because each slice's size shows its proportion of the total, while bar graphs also work well for comparing the amounts in different reservoirs, with bar height representing percentage, but line graphs would be inappropriate because they show change over time, not categorical data (different categories being compared at one time); key graph components include: clear title, labeled sections or axes, percentage values shown, and legend if using colors. Choice A is correct because a pie chart is appropriate for showing parts of a whole, which matches the data type, and a well-made graph must include title ('Distribution of Water on Earth'), labels (ocean, ice caps, groundwater, etc.), and percentages (97%, 2%, 0.6%, etc.), demonstrating understanding that graph type should match data characteristics and that complete graphs include all necessary components for interpretation. Choice B is incorrect because line graphs show change over time, not categorical comparisons; this error commonly occurs when students don't understand that different graph types serve different purposes, when they choose graphs they're most familiar with regardless of appropriateness, or when they create graphs without essential components like titles and labels; students may also not recognize that line graphs require sequential data (like time) while this data is categorical. To help students: Teach decision tree for graph selection: (1) Is it parts of a whole adding to 100%? → Pie chart. (2) Comparing amounts across categories? → Bar graph.

Question 7

Maya graphs oceans 97%, ice 2%, groundwater 0.6%, lakes 0.01%; which chart fits?​

  1. Use a pie chart with labeled slices and percentages (correct answer)
  2. Use a line graph because the data is in order
  3. Use a scatter plot to show a relationship
  4. Use a pie chart but leave off labels and title
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2).

Question 8

Which graph best displays Earth's water distribution: oceans 97%, ice 2%, groundwater 0.6%, other 0.4%?

  1. Use a line graph to show changes over time
  2. Use a pie chart to show parts of the whole (correct answer)
  3. Use a scatter plot to compare two variables
  4. Just write the percentages in a list
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2). Different types of data require different types of graphs; water distribution data shows parts of a whole (percentages that add to 100%), making pie charts (circle graphs) ideal because each slice's size shows its proportion of the total, while bar graphs also work well for comparing the amounts in different reservoirs, with bar height representing percentage, but line graphs would be inappropriate because they show change over time, not categorical data (different categories being compared at one time); key graph components include: clear title, labeled sections or axes, percentage values shown, and legend if using colors. Choice B is correct because a pie chart is appropriate for showing parts of the whole, which matches the data type of Earth's water distribution percentages adding up to 100%. Choice A is incorrect because a line graph shows changes over time, not categorical comparisons like water reservoirs; this error commonly occurs when students don't understand that different graph types serve different purposes or when they choose graphs they're most familiar with regardless of appropriateness. To help students: Teach decision tree for graph selection: (1) Is it parts of a whole adding to 100%? → Pie chart. (2) Comparing amounts across categories? → Bar graph. (3) Showing change over time? → Line graph. (4) Showing relationship between two variables? → Scatter plot.

Question 9

Carlos makes a bar graph for oceans 97%, ice 2%, groundwater 0.6%; what scale is best?

  1. Y-axis from 0%0\% to 100%100\% to match percentage data (correct answer)
  2. Y-axis from 0%0\% to 10%10\% so bars look larger
  3. No y-axis scale; only color the bars
  4. Use two y-axes for the same percentages
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2). Different types of data require different types of graphs; water distribution data shows parts of a whole (percentages that add to 100%), making pie charts (circle graphs) ideal because each slice's size shows its proportion of the total, while bar graphs also work well for comparing the amounts in different reservoirs, with bar height representing percentage, but line graphs would be inappropriate because they show change over time, not categorical data (different categories being compared at one time); key graph components include: clear title, labeled sections or axes, percentage values shown, and legend if using colors. Choice A is correct because a y-axis from 0% to 100% matches the percentage data, allowing accurate comparison in a bar graph. Choice B is incorrect because a y-axis from 0% to 10% distorts the data by making small percentages appear larger; this error commonly occurs when students manipulate scales without understanding accuracy. To help students: Teach decision tree for graph selection: (1) Is it parts of a whole adding to 100%? → Pie chart. (2) Comparing amounts across categories? → Bar graph. (3) Showing change over time? → Line graph. (4) Showing relationship between two variables? → Scatter plot. Practice with water distribution data: Give students the percentages and have them create both a pie chart and bar graph to see both work; emphasize essential components checklist: Title? Labels? Values shown? Appropriate type? Use graph paper or digital tools; model: 'The data shows percentages of total water, so we need to show parts of whole - pie chart is perfect.' Watch for: students who always use the same graph type regardless of data, who forget labels and titles, who can't explain why their choice is appropriate, or who use line graphs for categorical data; explicitly teach: Line graphs are for change over time (temperature each day), not for comparing categories (water in different places).

Question 10

Chen wants to compare oceans 97% to ice 2% and groundwater 0.6%; which graph helps most?​

  1. Use a bar graph with a 0%0\%–100%100\% y-axis scale (correct answer)
  2. Use a line graph to show a trend across categories
  3. Use a scatter plot to find correlation
  4. Use a bar graph but put percentages on the x-axis
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2). Different types of data require different types of graphs; water distribution data shows parts of a whole (percentages that add to 100%), making pie charts (circle graphs) ideal because each slice's size shows its proportion of the total, while bar graphs also work well for comparing the amounts in different reservoirs, with bar height representing percentage, but line graphs would be inappropriate because they show change over time, not categorical data (different categories being compared at one time); key graph components include: clear title, labeled sections or axes, percentage values shown, and legend if using colors. Choice A is correct because a bar graph with a 0%–100% y-axis scale is appropriate for comparing categories by percentage, ensuring accurate representation of the data's full range. Choice B is incorrect because a line graph shows trends across sequential data, not categories; this error commonly occurs when students apply the wrong graph type to non-temporal data. To help students: Teach decision tree for graph selection: (1) Is it parts of a whole adding to 100%? → Pie chart. (2) Comparing amounts across categories? → Bar graph. (3) Showing change over time? → Line graph. (4) Showing relationship between two variables? → Scatter plot. Practice with water distribution data: Give students the percentages and have them create both a pie chart and bar graph to see both work; emphasize essential components checklist: Title? Labels? Values shown? Appropriate type? Use graph paper or digital tools; model: 'The data shows percentages of total water, so we need to show parts of whole - pie chart is perfect.' Watch for: students who always use the same graph type regardless of data, who forget labels and titles, who can't explain why their choice is appropriate, or who use line graphs for categorical data; explicitly teach: Line graphs are for change over time (temperature each day), not for comparing categories (water in different places).

Question 11

Chen makes a pie chart for oceans 97%, ice 2%, groundwater 0.6%; what must be included?

  1. A title, labels, and percentages on slices (correct answer)
  2. Only colors, no labels or numbers
  3. A time line under the chart
  4. Dots showing paired data points
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2). Complete and effective graphs require essential components that make them interpretable and informative. For pie charts showing parts of a whole, these components include: a descriptive title, labels identifying each slice, and values (percentages) showing the size of each part. Without these elements, viewers cannot understand what the graph represents or interpret the data accurately. Colors alone provide no information about what each slice represents or its actual value. Choice A is correct because a title, labels, and percentages on slices are all essential components of an effective pie chart. The title tells what the graph shows ('Earth's Water Distribution'), labels identify each slice (oceans, ice, groundwater), and percentages (97%, 2%, 0.6%) provide precise values. This demonstrates understanding that graphs must communicate complete information to be useful. Choice B is incorrect because colors without labels or numbers make the graph uninterpretable - viewers wouldn't know what each slice represents. Choice C is incorrect because pie charts show categorical data, not time-based data. Choice D describes a scatter plot, not a pie chart. These errors commonly occur when students focus on making graphs look nice rather than communicating information, or when they confuse different graph types. To help students: Teach essential components checklist for pie charts: (1) Title - What does this show? (2) Labels - What is each slice? (3) Values - How big is each slice? (4) Legend if needed. Practice peer review: Students exchange graphs and check if they can understand the data without verbal explanation. If not, what's missing? Model: 'Can someone who's never seen my data understand this graph? They need to know what it shows (title), what each part is (labels), and how much (percentages).' Watch for: students who create colorful but unlabeled graphs, who forget titles, who assume viewers will 'just know' what slices represent, or who don't include actual values.

Question 12

Which graph type should NOT be used for oceans 97%, ice 2%, groundwater 0.6% data?

  1. Pie chart (circle graph) with slices
  2. Bar graph comparing reservoir percentages
  3. Line graph connecting category points (correct answer)
  4. Pie chart with a legend and labels
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2). Different types of data require different types of graphs. Water distribution data shows parts of a whole (percentages that add to 100%), making pie charts and bar graphs appropriate because they can show categorical comparisons. Line graphs, however, are specifically designed to show change over time or continuous relationships, requiring sequential data points. Water distribution categories (oceans, ice, groundwater) are discrete categories, not points in time or continuous variables. Key understanding: matching graph type to data structure is essential for accurate representation. Choice C is correct because line graphs should NOT be used for this categorical percentage data. Line graphs connect points to show trends or changes over time (like temperature throughout a day), but water distribution categories aren't sequential or time-based. Connecting oceans to ice to groundwater with a line implies a progression or relationship that doesn't exist. This demonstrates understanding that inappropriate graph types can misrepresent data. Choices A, B, and D are all appropriate because pie charts effectively show parts of a whole, and bar graphs allow comparison of categories. The inclusion of legends and labels (Choice D) enhances clarity without changing the appropriateness of the pie chart format. This error commonly occurs when students use line graphs as their default choice or don't understand that lines imply continuity or progression between points. To help students: Teach decision tree for graph selection with emphasis on what NOT to use: Line graphs are ONLY for (1) change over time or (2) continuous relationships. Ask: 'Does it make sense to draw a line from oceans to ice?' No, because they're separate categories, not connected points. Practice identifying inappropriate graphs: Show various graph types with water data and have students explain why each works or doesn't work. Model: 'Line graphs show trends. Is there a trend from oceans to ice to groundwater? No, they're just different places water exists.' Watch for: students who think any data can go in any graph, who connect categorical data with lines, or who can't articulate why a graph type is inappropriate.

Question 13

Chen wants to compare oceans 97% to ice 2% and groundwater 0.6%; which graph helps most?

  1. Use a bar graph with a 0%0\%–100%100\% y-axis scale (correct answer)
  2. Use a line graph to show a trend across categories
  3. Use a scatter plot to find correlation
  4. Use a bar graph but put percentages on the x-axis
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2). Different types of data require different types of graphs; water distribution data shows parts of a whole (percentages that add to 100%), making pie charts (circle graphs) ideal because each slice's size shows its proportion of the total, while bar graphs also work well for comparing the amounts in different reservoirs, with bar height representing percentage, but line graphs would be inappropriate because they show change over time, not categorical data (different categories being compared at one time); key graph components include: clear title, labeled sections or axes, percentage values shown, and legend if using colors. Choice A is correct because a bar graph with a 0%–100% y-axis scale is appropriate for comparing categories by percentage, ensuring accurate representation of the data's full range. Choice B is incorrect because a line graph shows trends across sequential data, not categories; this error commonly occurs when students apply the wrong graph type to non-temporal data. To help students: Teach decision tree for graph selection: (1) Is it parts of a whole adding to 100%? → Pie chart. (2) Comparing amounts across categories? → Bar graph. (3) Showing change over time? → Line graph. (4) Showing relationship between two variables? → Scatter plot. Practice with water distribution data: Give students the percentages and have them create both a pie chart and bar graph to see both work; emphasize essential components checklist: Title? Labels? Values shown? Appropriate type? Use graph paper or digital tools; model: 'The data shows percentages of total water, so we need to show parts of whole - pie chart is perfect.' Watch for: students who always use the same graph type regardless of data, who forget labels and titles, who can't explain why their choice is appropriate, or who use line graphs for categorical data; explicitly teach: Line graphs are for change over time (temperature each day), not for comparing categories (water in different places).

Question 14

Which graph best displays oceans 97%, ice 2%, groundwater 0.6% as parts of Earth's water?

  1. Pie chart (circle graph) with labeled percentages (correct answer)
  2. Line graph showing change over time
  3. Scatter plot comparing two variables
  4. List the data in words only
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2). Different types of data require different types of graphs. Water distribution data shows parts of a whole (percentages that add to 100%), making pie charts (circle graphs) ideal because each slice's size shows its proportion of the total. Bar graphs also work well for comparing the amounts in different reservoirs, with bar height representing percentage. Line graphs would be inappropriate because they show change over time, but water distribution is categorical data (different categories being compared at one time), not a time series. Key graph components include: clear title, labeled sections or axes, percentage values shown, and legend if using colors. Choice A is correct because pie charts are specifically designed to show parts of a whole, which perfectly matches this data showing how Earth's water is distributed across different reservoirs. A well-made pie chart must include title ('Distribution of Water on Earth'), labels (oceans, ice caps, groundwater), and percentages (97%, 2%, 0.6%). This demonstrates understanding that graph type should match data characteristics and that complete graphs include all necessary components for interpretation. Choices B and C are incorrect because line graphs show change over time and scatter plots show relationships between two variables, neither of which applies to categorical percentage data. Choice D is incorrect because it lacks visual representation, which is essential for data comprehension. This error commonly occurs when students don't understand that different graph types serve different purposes or when they choose graphs they're most familiar with regardless of appropriateness. To help students: Teach decision tree for graph selection: (1) Is it parts of a whole adding to 100%? → Pie chart. (2) Comparing amounts across categories? → Bar graph. (3) Showing change over time? → Line graph. (4) Showing relationship between two variables? → Scatter plot. Practice with water distribution data: Give students the percentages and have them create both a pie chart and bar graph to see both work. Emphasize essential components checklist: Title? Labels? Values shown? Appropriate type? Model: 'The data shows percentages of total water, so we need to show parts of whole - pie chart is perfect.' Watch for: students who always use the same graph type regardless of data, who forget labels and titles, who can't explain why their choice is appropriate, or who use line graphs for categorical data.

Question 15

A bar graph shows oceans 97%, ice 2%, groundwater 0.6%; what y-axis scale is best?

  1. 0% to 10% scale
  2. 0% to 50% scale
  3. 0% to 100% scale (correct answer)
  4. 1% to 5% scale
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2). When creating bar graphs, the y-axis scale must accommodate all data values while maintaining readability. With data ranging from 0.6% to 97%, the scale must reach at least 97% to display all bars. A 0% to 100% scale is standard for percentage data because it shows the full possible range and helps viewers understand the data in context of the whole. Scales that are too small would cut off the ocean bar, while unnecessarily large scales waste space. Key concept: appropriate scaling ensures all data is visible and proportions are accurately represented. Choice C is correct because a 0% to 100% scale accommodates all values (including the 97% ocean bar) while showing the complete percentage range. This scale helps students understand that these percentages represent parts of all Earth's water, with 100% being the maximum possible. It also provides good spacing for reading values and comparing bar heights. Choices A and B are incorrect because they would cut off the ocean bar at 97%, making the graph incomplete and misleading. Choice D is incorrect because it couldn't even show the ice bar at 2%, let alone the ocean bar. These errors commonly occur when students don't check that their scale includes all data values or when they try to zoom in on small values without considering the full range. To help students: Teach scale selection process: (1) Find the largest value in your data (97%). (2) Choose a scale maximum at or above this value. (3) For percentages, 0-100% is usually best. (4) Check that all bars fit. Practice with different scales: Have students draw the same data with different y-axis scales to see how it affects the graph's appearance and readability. Model: 'My biggest value is 97%, so my scale must go at least that high. Since these are percentages of a whole, 0-100% makes sense.' Watch for: students who choose scales based on the smallest values and forget about large ones, who don't understand that percentage scales typically go to 100%, or who create scales that distort the visual comparison between bars.

Question 16

Jamal graphs oceans 97%, ice 2%, groundwater 0.6%, atmosphere trace; which graph is appropriate?

  1. Use a bar graph to compare categories by percentage (correct answer)
  2. Use a scatter plot to show paired measurements
  3. Use a line graph to show a pattern over time
  4. Just make a list; graphs are not needed
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2). Different types of data require different types of graphs; water distribution data shows parts of a whole (percentages that add to 100%), making pie charts (circle graphs) ideal because each slice's size shows its proportion of the total, while bar graphs also work well for comparing the amounts in different reservoirs, with bar height representing percentage, but line graphs would be inappropriate because they show change over time, not categorical data (different categories being compared at one time); key graph components include: clear title, labeled sections or axes, percentage values shown, and legend if using colors. Choice A is correct because a bar graph is appropriate for comparing categories by percentage, matching the reservoir data. Choice C is incorrect because a line graph shows patterns over time, not static categories; this error commonly occurs when students misidentify data types. To help students: Teach decision tree for graph selection: (1) Is it parts of a whole adding to 100%? → Pie chart. (2) Comparing amounts across categories? → Bar graph. (3) Showing change over time? → Line graph. (4) Showing relationship between two variables? → Scatter plot. Practice with water distribution data: Give students the percentages and have them create both a pie chart and bar graph to see both work; emphasize essential components checklist: Title? Labels? Values shown? Appropriate type? Use graph paper or digital tools; model: 'The data shows percentages of total water, so we need to show parts of whole - pie chart is perfect.' Watch for: students who always use the same graph type regardless of data, who forget labels and titles, who can't explain why their choice is appropriate, or who use line graphs for categorical data; explicitly teach: Line graphs are for change over time (temperature each day), not for comparing categories (water in different places).

Question 17

Sofia uses fresh water 3% and salt water 97%; which visual best shows this distribution?​

  1. Use a pie chart with two labeled sections (correct answer)
  2. Use a scatter plot with points for each type
  3. Use a line graph to show change over years
  4. Use a pie chart but do not show percentages
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2). Different types of data require different types of graphs; water distribution data shows parts of a whole (percentages that add to 100%), making pie charts (circle graphs) ideal because each slice's size shows its proportion of the total, while bar graphs also work well for comparing the amounts in different reservoirs, with bar height representing percentage, but line graphs would be inappropriate because they show change over time, not categorical data (different categories being compared at one time); key graph components include: clear title, labeled sections or axes, percentage values shown, and legend if using colors. Choice A is correct because a pie chart with two labeled sections is appropriate for showing parts of the whole for fresh and salt water percentages adding to 100%. Choice C is incorrect because a line graph shows change over years, but this data is static categories without a time element; this error commonly occurs when students confuse temporal trends with categorical distributions. To help students: Teach decision tree for graph selection: (1) Is it parts of a whole adding to 100%? → Pie chart. (2) Comparing amounts across categories? → Bar graph. (3) Showing change over time? → Line graph. (4) Showing relationship between two variables? → Scatter plot. Practice with water distribution data: Give students the percentages and have them create both a pie chart and bar graph to see both work; emphasize essential components checklist: Title? Labels? Values shown? Appropriate type? Use graph paper or digital tools; model: 'The data shows percentages of total water, so we need to show parts of whole - pie chart is perfect.' Watch for: students who always use the same graph type regardless of data, who forget labels and titles, who can't explain why their choice is appropriate, or who use line graphs for categorical data; explicitly teach: Line graphs are for change over time (temperature each day), not for comparing categories (water in different places).

Question 18

Keisha wants parts-of-a-whole for oceans 97%, ice 2%, groundwater 0.6%; which graph matches?

  1. Scatter plot with dots for each reservoir
  2. Pie chart showing each reservoir as a proportion (correct answer)
  3. Line graph connecting reservoirs in order
  4. Bar graph without labels or a title
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2). Different types of data require different types of graphs; water distribution data shows parts of a whole (percentages that add to 100%), making pie charts (circle graphs) ideal because each slice's size shows its proportion of the total, while bar graphs also work well for comparing the amounts in different reservoirs, with bar height representing percentage, but line graphs would be inappropriate because they show change over time, not categorical data (different categories being compared at one time); key graph components include: clear title, labeled sections or axes, percentage values shown, and legend if using colors. Choice B is correct because a pie chart showing each reservoir as a proportion is ideal for parts-of-a-whole data. Choice C is incorrect because a line graph connects points for trends, not categories; this error commonly occurs when students don't match graph type to data structure. To help students: Teach decision tree for graph selection: (1) Is it parts of a whole adding to 100%? → Pie chart. (2) Comparing amounts across categories? → Bar graph. (3) Showing change over time? → Line graph. (4) Showing relationship between two variables? → Scatter plot. Practice with water distribution data: Give students the percentages and have them create both a pie chart and bar graph to see both work; emphasize essential components checklist: Title? Labels? Values shown? Appropriate type? Use graph paper or digital tools; model: 'The data shows percentages of total water, so we need to show parts of whole - pie chart is perfect.'

Question 19

Sofia graphs oceans 97%, ice 2%, groundwater 0.6% in a bar graph; what goes on x-axis?

  1. Percentages (97, 2, 0.6)
  2. Reservoir names (oceans, ice, groundwater) (correct answer)
  3. Time in years
  4. Temperature in degrees
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2). In bar graphs, the x-axis (horizontal) typically shows categories being compared, while the y-axis (vertical) shows the measured values. For water distribution data, we're comparing different water reservoirs (categories), so these category names go on the x-axis. The percentage values are then represented by bar height on the y-axis. This standard arrangement allows viewers to read category names easily while comparing heights. Key concept: x-axis for 'what' (categories), y-axis for 'how much' (values). Choice B is correct because reservoir names (oceans, ice, groundwater) are the categories being compared, and categories belong on the x-axis in a bar graph. Each bar represents one reservoir, positioned above its label on the x-axis, with height showing its percentage. This demonstrates understanding of standard graph conventions and how axes serve different purposes. Choice A is incorrect because percentages are the values being measured, which belong on the y-axis as bar heights, not x-axis labels. Choices C and D are incorrect because this data doesn't involve time or temperature - these are unrelated variables. These errors commonly occur when students confuse which information goes on which axis or try to force irrelevant variables into their graphs. To help students: Teach axis selection with memory device: 'x is for what (categories), y is for how much (values).' Practice labeling empty graphs: Give students data and have them just label axes before drawing bars. Use sentence frames: 'I'm comparing [categories], so [categories] go on the x-axis. I'm measuring [values], so [values] go on the y-axis.' Model: 'I'm comparing oceans, ice, and groundwater - these are my categories for the x-axis. Their percentages will be shown by bar height.' Watch for: students who put numbers on both axes, who reverse the standard arrangement, or who can't distinguish between categories and values in their data.

Question 20

Which graph best displays Earth's water distribution: oceans 97%, ice 2%, groundwater 0.6%, other 0.4%?​

  1. Use a line graph to show changes over time
  2. Use a pie chart to show parts of the whole (correct answer)
  3. Use a scatter plot to compare two variables
  4. Just write the percentages in a list
Explanation: This question tests students' ability to graph water distribution data using appropriate representations (NGSS 5-ESS2-2). Different types of data require different types of graphs; water distribution data shows parts of a whole (percentages that add to 100%), making pie charts (circle graphs) ideal because each slice's size shows its proportion of the total, while bar graphs also work well for comparing the amounts in different reservoirs, with bar height representing percentage, but line graphs would be inappropriate because they show change over time, not categorical data (different categories being compared at one time); key graph components include: clear title, labeled sections or axes, percentage values shown, and legend if using colors. Choice B is correct because a pie chart is appropriate for showing parts of the whole, which matches the data type of Earth's water distribution percentages adding up to 100%. Choice A is incorrect because a line graph shows changes over time, not categorical comparisons like water reservoirs; this error commonly occurs when students don't understand that different graph types serve different purposes or when they choose graphs they're most familiar with regardless of appropriateness. To help students: Teach decision tree for graph selection: (1) Is it parts of a whole adding to 100%? → Pie chart. (2) Comparing amounts across categories? → Bar graph. (3) Showing change over time? → Line graph. (4) Showing relationship between two variables? → Scatter plot. Practice with water distribution data: Give students the percentages and have them create both a pie chart and bar graph to see both work; emphasize essential components checklist: Title? Labels? Values shown? Appropriate type? Use graph paper or digital tools; model: 'The data shows percentages of total water, so we need to show parts of whole - pie chart is perfect.' Watch for: students who always use the same graph type regardless of data, who forget labels and titles, who can't explain why their choice is appropriate, or who use line graphs for categorical data; explicitly teach: Line graphs are for change over time (temperature each day), not for comparing categories (water in different places).
