In this activity, learners discover that some things only stand up while they are spinning.

Groups of learners are provided with a generic car base and an egg. Their mission: design a device/enclosure to protect the egg on or in the car as it rolls down a ramp with increasing slopes.

Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, size, and bounce height.

Learners drop two different masses of play dough and observe how long it takes them to hit the ground.

In this activity, learners will build thier own balance scale. Learners will explore weight and comparison through this activity.

This activity (located on page 3 of the PDF under GPS: Lava Flow Activity) is a full inquiry investigation into the relationship between an object’s mass and the distance it is thrown by a catapult.

Learners examine collisions between two skateboards carrying different masses. They learn about conservation of momentum in collisions.

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.
