Create a Compass
Source Institutions
In this activity, learners use simple materials to build their own compass.
Water "Digs" It!
Source Institutions
In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.
Cookie Paleontology
Source Institutions
In this activity, learners will explore paleontology and archaeology. They will learn about technique as they excavate raisins and chocolate chips from cookies.

In this activity, learners will build a bee hotel for pollinators. Learners will explore building and ecology through this activity.
Taste Match Game
Source Institutions
In this activity (3rd activity on the page), learners taste test different foods and categorize them as sweet, bitter, sour, or salty. Learners compare their results with the group.
Film Canister Rocket
Source Institutions
In this activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions.
Floating Head Cup
Source Institutions
In this activity, learners watch a figure "magically" float up through the air.
How does the Atmosphere keep the Earth Warmer?
Source Institutions
In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.
Kaleidoscope
Source Institutions
In this activity, learners investigate the reflective properties of light and mirrors as they make a kaleidoscope.
