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.

In this activity (page 2 of PDF under GPS: Glaciers Activity), learners will measure the rate at which water streams out of a leaky cup.

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

In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.
