Delta, Delta, Delta
Source Institutions
In this experiment, learners construct an equilateral triangle using graph paper, a pencil, protractor and ruler. They also make a "laser triangle" using a laser pointer and front-silvered mirrors.

How Big is Small
Source Institutions
In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.
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
