The Exploratorium

In this fun and interactive online exhibit, the straight lines of a tile wall appear to curve. The learner moves the rows of tiles and changes the color of the grout to achieve the intriguing effect.

In this activity best suited as a demonstration, learners observe that when a piece of iron gets too hot, it loses its ability to be magnetized.

Closing one eye eliminates one of the clues that your brain uses to judge depth. Trying to perform a simple task with one eye closed demonstrates how much you rely on your depth perception.

In this activity, learners use pegboard and straws to build a three-dimensional model of the periodic table.

In this activity, learners manipulate film to create homemade movies. Scratch Film, also known as Direct Animation, is the process of drawing and scratching designs directly onto film.

In this activity, learners make a yeast-air balloon to get a better idea of what yeast can do. Learners discover that the purpose of leaveners like yeast is to produce the gas that makes bread rise.

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

In this activity, learners use simple materials to simulate the effect of X-rays in a safe way. Learners place a piece of window screen over a box and a cardboard pattern on top of the screen.

This is an online exhibit about color perception. Learners set a random background color and then try to mix red, blue, and green light to match.

In this simulation game, learners play as predators equipped with genetically different “mouths” (utensils) and hunt for “prey” (assorted beans).
