Students explore different size circles to discover the relationship between diameter and circumference. In this circles and Pi lesson, students construct simple parachutes using circle patterns of varying sizes. Students predict the...

Students predict how a parachute works. They draw a design of a parachute. Students construct a parachute that is able to slow the fall of several pennies in a cup and an egg. They explain how a parachute creates air resistance to...

Students create a simple paper parachute. In this parachute design lesson, students examine the effects of the wind and make napkin parachutes.  

Students construct a pathfinder that could land an egg safely. In this physics lesson, students explain the factors affecting the dynamics of falling objects. They evaluate their pathfinder design.
