In this activity, students will answer a series of short conceptual clicker questions designed to teach them to think about projectile motion.

Prior to the activity, the instructor gives a lecture on projectile motion. The first clicker question is then introduced, and is a simple question about projectile motion. Once student responses have been collected, if more than 75% of students answered correctly the instructor explains the correct answer, otherwise students are told to pair up and discuss the question then re-polled.

This is repeated for the second, then third problem. These problems are more difficult, requiring students to think about ...

Prior to the activity, the instructor gives a lecture on projectile motion. The first clicker question is then introduced, and is a simple question about projectile motion. Once student responses have been collected, if more than 75% of students answered correctly the instructor explains the correct answer, otherwise students are told to pair up and discuss the question then re-polled.

This is repeated for the second, then third problem. These problems are more difficult, requiring students to think about the relationship between the height, air time, and distance of a projectile. After the third problem, the instructor highlights the key points, emphasizing that the time spent in the air by a projectile is directly related to its height, not to the distance traveled.

Read Less -- Students learn to recognize distinction between the horizontal and vertical components of projectile motion.
- Students learn that it is the vertical height of a projectile that determines the time spent in the air, not the horizontal distance traveled.
