Explores the principles of light, reflection, and magnification through hands-on experiments. Children observe how a magnifying glass focuses sunlight to create heat, examine the effects of light ...

To investigate the reflection of light by different types of surface, and the refraction of light by different substances. Remove the block. Join the crosses to show the paths of the light rays ...

Dependent Variable is the angle of refraction ... light will bend from a bigger initial angle, and so the angle of refraction will also be bigger. Low voltage power pack, a 12V ray box, a single ...
