Here’s a fun exploration of optics that tastes as good as it teaches. -- Students make their own optical lenses with concentrated gelatin providing you with an easy and inexpensive way to provide demonstrations in real and virtual imaging, spherometry, ray tracing, and the application of lens formulas. -- Kit contains: 4 Petri dishes, 4 large watch glasses, 1 spherometer, 1 plastic tube with scale, 3 packages of gelatin, and an instruction guide. -- Note: With moderate handling these lenses will last for several days (as long as students don’t eat them!). -- |
