PhET Simulation: The Greenhouse Effect - May 1, 2013
Earth Observatory: Solar Prominence - Apr 1, 2013
Visit Earth Observatory: Solar Prominence, and take a look at these two images of a solar prominence. How does a prominence look when you see it at the sun itself, compared when you see it against the darkness of space? When you see the prominence against the sun, it's usually called a "filament." To learn more, read the text under the images.
Kitchen Sink Experiments: Bubbles that sink: Antibubbles - Feb 1, 2013
Think about a bubble: It's a thin film of water, with air inside and outside. Now imagine the opposite of a bubble: That would be a thin film of air, enclosing water inside and surrounded by water outside. This structure is called an antibubble.
Spectral Lines - Jan 1, 2013
Auroras are produced when charged particles from the sun collide with atoms in the atmosphere and transfer energy to them. This energy is then given off as light. Check out Spectral Lines to find out how atoms produce light.
Feather Drop - Dec 1, 2012
Felix Baumgartner was nearly in free fall as he stepped out of his capsule at an altitude of 39 kilometers (24 miles). At this altitude, the atmosphere is so thin that a falling object experiences hardly any air resistance, so it accelerates rapidly to very high speed (Baumgartner's skydive exceeded the speed of sound).
Liquid Crystal IR Detector - Nov 1, 2012
Go to Liquid Crystal IR Detector for an experiment that shows how a liquid crystal can detect infrared radiation.
