Creating Reservoirs Under Roads and Parking Lots
Porous pavement allows water to pass down to the water table, rather than run off into storm drains.
Pinhole Viewer
By building their own pinhole camera, students will learn how cameras, telescopes, and their own eyes use light in similar ways.
Solar Spotting
Using the Swedish Solar Telescope, a ground-based observatory, Goran Scharmer and colleagues probe the penumbra—that’s the stringy structure around the perimeter of the dark part of the sunspot.
Delicious Smelling Chemistry
Use household materials to investigate and explore your ability to smell an odor, then compare and contrast results to determine if some individuals have a better sense of smell than others. Observe the Maillard reaction and how different odor molecules are released into the air.
Desktop Diaries: Michio Kaku
Theoretical physicist and futurist Michio Kaku takes us on a tour of his office, where he writes his bestsellers and records his radio shows.
Magnified Sun Burns
At the right angle, a magnifying glass will concentrate sunshine into a burning hot circle.
Learn how to cultivate moss in a terrarium
Learn about the biological needs and lifecycle of mosses by cultivating and maintaining your own moss terrarium.
Explosive Science
In this activity, students will use household materials to investigate and explore how the release of carbon dioxide gas from a chemical reaction can cause a small-scale explosion. Students then will experiment with variables to determine which factors launch a film canister the highest.
Fun With Optics: Can You Explain How A Telescope Works?
Use simple materials to explore the properties of reflection and refraction as you discover how optics work in telescopes.
Model the flow of a river with a simple stream table.
Investigate river formations in different landscape scenarios from a flat plain to a terrain with hills and valleys.
