Representing Weather Data - 3rd Grade Science

1. Find the total rainfall if a table shows $1$ in. on Monday and $2$ in. on Tuesday.

   $3$ in. Add the rainfall amounts: $1 + 2 = 3$ inches.

2. What is the correct way to record a missing weather measurement in a table?

   Leave it blank or write N/A (not available). Shows data is missing, not zero.

3. Which day has more rainfall: Day A $0.4$ in. or Day B $0.6$ in.?

   Day B ($0.6$ in.). $0.6$ inches is greater than $0.4$ inches.

4. Find the difference in temperature if the table shows $70^\circ\text{F}$ and $65^\circ\text{F}$.

   $5^\circ\text{F}$. Subtract to find difference: $70 - 65 = 5$ degrees.

5. Identify the day with the least rainfall: Mon $0.4$ in., Tue $0$ in., Wed $0.2$ in.

   Tuesday ($0$ in.). Zero inches means no rain fell that day.

6. Identify the correct y-axis scale if rainfall values are $0$ to $10$ cm and you count by $2$.

   $0, 2, 4, 6, 8, 10$. Counting by $2$ from $0$ to $10$ gives these values.

7. Which graph type is best for showing how the parts of a day's weather types make a whole?

   Pie chart (circle graph). Shows parts of a whole as slices of a circle.

8. Find and correct the graph error: The y-axis shows temperature but has no unit.

   Add the unit to the y-axis label (for example, °F). Units are essential for understanding what numbers represent.
