In this optics activity, learners make a "light fountain" from a clear plastic bottle, flashlight, and other simple materials.

In this optics activity, learners work in pairs to explore how mirrors work. Learners use tape to mark the angles needed to see each other's reflection in a wall mirror.

In this activity, learners explore why they can see colors in bubbles and why they change.

In this optics activity, learners use water to make a coin "appear" and "disappear." Use this activity to demonstrate how light refracts and introduce light as waves.

In this optics activity, learners make a lens and explore how the eye manipulates the light that enters it.

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

In this activity, learners create a water prism to break light into the seven colors of the rainbow.
