In this activity, learners create a cylindrical mirror to see themselves as others see them.

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).

This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

In this optics activity, learners make a simple telescope using two lenses and a cardboard tube. Learners construct the telescope and then calculate its magnification.

In this hands-on activity, learners build their own kaleidoscopes and explore how light can reflect of off surfaces such as mirrors, to produce beautiful patterns.
