Super Gelatin
Source Institutions
Can gelatin (like Jell-O ®) change the speed of light?
Light on Other Planets
Source Institutions
In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe
