Get the class thinking about why particular objects and animals are shaped the way they are. Considering water resistance and shape, learners assess a series of images and how those objects function in water. They finish by conducting a...

Define six common forces: propulsion, air resistance, water resistance, friction, gravity, and upthrust. A picture of a Smart Car is displayed with arrows showing all of the forces acting on it when it is motion. A picture of a rubber...

Fifth graders test the shelters that were built in a prior activity. They determine the level of durability and water resistance of these shelters through a scientific investigation.

In this activity, the students will use wax paper shaped as leaves and kite string to build a shelter to protect them from the rain. The students will then test the shelters for durability and water resistance.
