In this activity, a lightbulb is placed in front of a concave mirror. The actual lightbulb is not visible to the viewer, but the viewer can see the mirror image of the lightbulb formed in space.

In this physics activity, learners conduct two experiments to explore free-falling.

In this activity about light and reflection, learners discover that what you see is often affected by what you expect to see.

In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

The Drawing Board consists of a marking pen that remains stationary and a platform that swings beneath the pen, acting as a pendulum.

In this fun optics activity, learners explore principles of light, reflection (mirrors), and perception. Learners work in pairs and sit on opposite sides of a "two-way" mirror.

With little more than a plastic bottle, some vinyl tubing, and a length of PVC pipe, make a rocket and a rocket launcher and investigate how rockets fly.

In this activity, learners use pegboard and straws to build a three-dimensional model of the periodic table.

In this activity and demonstration about electricity and magnetism, learners observe how the current generated when one copper coil swings through a magnetic field starts a second coil swinging.
