# 2nd Grade Science : Analyze data from different materials

## Example Questions

### Example Question #1 : Analyze Data From Different Materials

Based on the data provided, which material should Myles NOT use to build his shelf?

Material 1

There is no way to tell which material Myles should not use.

Material 2

Material 3

Material 2

Explanation:

This data table provides information to analyze different materials. In the case of Myles, "Material 2" is weak and soft, which does not make an excellent material for a shelf. He would want to pick a material that is hard and would support the weight of items displayed.

### Example Question #2 : Analyze Data From Different Materials

Which of the following properties are most important for the purpose of building a bookshelf?

Texture

Hardness

Strength

Flexibility

Strength

Explanation:

Building a bookshelf is a big project, and the material needs to be able to support a lot of weight. The most important property for the building of a bookshelf is strength. If the bookshelf material is weak, it will fall, and the books will spill everywhere.

### Example Question #3 : Analyze Data From Different Materials

Blair and her class build two bridges as a competition. The goal was to get the most cars across before the bridge collapsed. They have to choose the best design to improve on and send to the science fair.

Based on the data table, which bridge should they select and why?

Bridge A; it looked the coolest out of the two bridges and the class got to eat popsicles to make it

Bridge B; it held three cars before it fell and that is pretty good

Bridge B; the class got to chew gum to make this bridge so they should pick it

Bridge A; it held the most cars, wobbled but did not fall

Bridge A; it held the most cars, wobbled but did not fall

Explanation:

When building a bridge in real-life, there is a massive amount of planning and testing done to ensure it is safe and sturdy. This class had good plans and materials for building both bridges, but "Bridge A" seems like the most reliable choice for the science fair entry. It was able to hold up six toy cars and did not fall. It did wobble some so the class can make improvements on that portion of the bridge. "Bridge B" collapsed after the weight of three toy cars, so it doesn't seem like the most sturdy bridge.

### Example Question #4 : Analyze Data From Different Materials

Charlie decided to test the rocks he found in his yard. He took each one and squeezed it as hard as he could and recorded what happened. Then he put them in a hard plastic container and shook each one as hard as he could. He recorded his observations.

Below are the observations Charlie recorded. Based on this information, which rock is the hardest of the group?

Rock 2

Rock 1

Rock 3

Rock 4

Rock 2

Explanation:

The hardest rock of the group based on the data Charlie collected is "Rock 2". This rock did not break when shaken or squeezed. All of the other stones broke during one or more of the tests. After analyzing the data, it can be concluded that "Rock 2" is the hardest.

### Example Question #5 : Analyze Data From Different Materials

Charlie decided to test the rocks he found in his yard. He took each one and squeezed it as hard as he could and recorded what happened. Then he put them in a hard plastic container and shook each one as hard as he could. He recorded his observations.

Below are the observations Charlie recorded. Based on this information, which rock is the weakest of the group?

Rock 3

Rock 4

Rock 1

Rock 2

Rock 4

Explanation:

The rock that was the least hard out of the group is "Rock 4". This rock not only broke when it was shaken but also when it was squeezed. It is the only rock from all four tests to break under both conditions. After collecting and analyzing the data, "Rock 4" is the weakest.

### Example Question #6 : Analyze Data From Different Materials

Based on the data provided, which material should Ash use to build his shelf?

Material 2

Material 3

None of these materials

Material 1

Material 3

Explanation:

This data table provides information to analyze different materials. In the case of Myles, "Material 2" is weak and soft, which does not make an excellent material for a shelf. He would want to pick a material that is hard and would support the weight of items displayed. This leaves "Materials 1 and 3" for consideration. "Material 1" is flexible, which could be a poor quality for a shelf. "Material 3" is strong, hard, and not flexible; it would be the best material for a shelf.

### Example Question #7 : Analyze Data From Different Materials

Which of the following properties are most important when choosing a paper towel to clean up a spill?

Absorbency

Flexibility

Color

Hardness

Absorbency

Explanation:

Paper towels are used to clean up spills, and no one wants to waste money on something that doesn't work. The material needs to clean up the mess quickly and efficiently. The most important property for a paper towel is its absorbency. If the paper towel is not absorbent, it will not clean up the mess.

### Example Question #8 : Analyze Data From Different Materials

Ms. Dube's class was testing the strength of different types of adhesive products to determine which was best for holding up classroom posters. She split the groups up and gave them four products and four signs. Their results are in the data table below.

Which material would be the best for Ms. Dube to use in her classroom to hang posters?

Liquid Glue

Glue Stick

Tape

Sticky Putty

Sticky Putty

Explanation:

Materials can be tested for a specific purpose or quality. The data from that test can be analyzed to determine which material is preferred for a job or task. Ms. Dube's class discovered that sticky putty held the poster up to the wall for the longest amount of time, so it would be the best choice for an adhesive in the classroom.

### Example Question #9 : Analyze Data From Different Materials

Ms. Dube's class was testing the strength of different types of adhesive products to determine which was best for holding up classroom posters. She split the groups up and gave them four products and four signs. Their results are in the data table below.

Which material would be the worst for Ms. Dube to use in her classroom to hang posters?

Sticky Putty

Liquid Glue

Glue Stick

Tape

Liquid Glue

Explanation:

The liquid glue would be the worst adhesive product for hanging posters in Ms. Dube's classroom. The liquid glue only held the poster in place for three minutes before it fell off the wall. This material is suited for other purposes, but based on this data, holding signs on the wall is not one of them.

### Example Question #10 : Analyze Data From Different Materials

Hayley is baking a cake for the school bake sale. She is trying to choose a frosting flavor and wants to make something that is a bit healthier. She compares the amount of sugar in each frosting and wants to choose the one with the least sugar. Which frosting should she choose?

Strawberry Sunset

Orange Dream

Vanilla Blast

Chocolate Thunder
