In this optics activity, learners explore how many objects they can see in a set of mirrors (hinged like a book) at various angles.

In this optics activity, learners experiment with polarizers (small dark rectangles) to examine light intensity.

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 use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.
