Question

1. which of the following could be a good way to show the data the students collected about shadows?

a. a pie chart showing different constellations
b. a bar graph showing shadow lengths at different times of day
c. a table listing the names of stars
d. a map of the school playground

Explanation:

A bar graph is suitable for showing changes over time (different times of day in this case). A pie chart is for showing proportions of a whole (not relevant here). A table listing names of stars is not related to shadow lengths. A map of the school playground is also not relevant to shadow - length data.

Answer:

B. A bar graph showing shadow lengths at different times of day
