How Far?
To learn how friction affects motion, learners build a measurement tool from a rubber band and other simple materials.

Breaking Beams
Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

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

Swing in Time
Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.
Simple Submarine
Source Institutions
Using simple, inexpensive items, learners build and test submarine models.

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

Swinging Yo-Yo
Source Institutions
Learners build a pendulum from a yo-yo, and then design their own experiment to determine what affects the pendulum's period of swing.
