The Exploratorium

In this activity, learners make a photographic image--without a camera!

In this physics crime lab or demonstration, learners pretend they are criminologists and must find the "muzzle velocity" (speed of the bullet as it leaves the gun) of a gun used to commit a crime.

In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts.

In this activity, learners create a cylindrical mirror to see themselves as others see them.

In this activity, learners conduct a simple test to find their blind spot.

In this activity, learners explore how changes in fluid pressure affect the buoyancy of a Cartesian diver inside a plastic soda bottle.

In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.

In this collection of demonstrations, learners explore Newton's Laws of Motion.

In this activity, learners hook up a hair to a lever system and create a hair hygrometer to measure changes in humidity.

Fat is a very important component in our diet. It's the most efficient source of energy in our bodies, and plays an important role in the flavor of foods.
