Where’s the Octopus?
When marine biologist Roger Hanlon captured the first scene in this video he started screaming.
Tending Crops On A Brooklyn Rooftop
A rooftop farm in Brooklyn grows vegetables and doubles as a green roof, insulating the warehouse below.
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.
How to Cultivate Moss
In this activity, to learn about the biological needs of mosses, students will grow and maintain their own moss terrarium. Through daily maintenance and observation, students will identify those factors necessary for the successful cultivation of moss.
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.
