How do polarized sunglasses work and why can’t I read my computer screen when I’m wearing them? How does light bend when it enters a different media? Why does it look like objects are behind mirrors? Watch your students become scientists as they dig into these fascinating questions. These three different lab activities can be used alone or in tandem, depending on your equipment and needs.
LEARN TO USE SCIENTIFIC EQUIPMENT:
• Laser pointers
• Transparent mirror
• Polarizing filters (polarizing sunglasses can be substituted
SOME OF THE SKILLS AND TASKS INVOLVED:
• Use laser pointers to show how light moves through various lenses.
• Use polarizing filters to show how light can be blocked depending on their orientation.

Extensive teacher notes address the many questions that come up. You shouldn’t have to do outside research on this topic unless you want to. Specific charts and graphic organizers have keys.
Each lab takes between 20 and 30 minutes.
