The chart to the left is a chart of the 413 college students' responses to the following true/false question.

We experience seasons because of the earth's changing distance to the sun - closer in summer, farther in winter.

-True

-False

Almost 2/3 of the students answered TRUE.

The correct answer is false, the Earth's seasons are due to the tilt of the Earth. It is clear that if these were the results I obtained in my own elementary classroom I would definitely have to revisit the topic, and probably reteach, so that the students obtained a better understanding.
