This activity groups items related to motion that seem similar and challenges students to chose which item in the group is not like the others. Students use supporting evidence to explain their reasoning.
Note that the Playground Physics app is not required for this lesson.
Introduce the Activity (5 minutes)
Activity (15 minutes)
Discussion (20 minutes)
Remember these responses are only best answers and students may come up with alternative responses. As long as their claim is supported with enough evidence or reasoning, it is acceptable.
Row 1 Sample response: Mass is not related to motion; the motion of an object can be described by its position, direction of motion, and speed; so the mass is the odd one out.
Row 2 Sample response: The average speed is calculated as total distance over time traveled; instantaneous speed is the odd one out as the others are “ingredients” of average speed.
Row 3 Sample response: A dropped ball has just one dimension of motion (vertical motion); all the other examples involve two-dimensional movement (horizontal and vertical).
Row 4 Sample response: A person riding on a merry-go-round goes in three dimensions (up and down on the horse, and around in a circle), all the others have one
or two-dimensional movement, which can be filmed by the app.
