Personal Pinhole Theater
Source Institutions
Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

Earth Atmosphere Composition
Source Institutions
In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.
