Gelatin Prism

In this activity, learners make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction. If learners use a white light source, this activity also shows them how white light is actually made up of many colors. Adult supervision recommended.
