In this activity, learners build helicopters and launchers using wooden dowels and scrap paper. Use this activity to explore rotational motion and kinetic and potential energy.

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

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

In this activity, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.

In this exploratory activity, learners experiment, observe and determine how various toys change from one form of energy to another.

In this activity, learners build magnetic towers to explore the forces and properties of magnets.
