Align four color transparencies, each one a single color (cyan, magenta, yellow, and black), and see a beautiful full color image.

In this activity, learners "dance" (move back and forth at varying speeds) by reading a graph. This is a kinesthetic way to help learners interpret and understand how motion is graphed.

In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.

Oboes's unique sound originates from the two small reeds a musician blows into. Make your own double reed instrument out of straw!

Find out what it would be like to have ears shaped differently from your own! Design and make different animal ears then try them out.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

In this activity, learners explore scale by using building cubes to see how changing the length, width, and height of a three-dimensional object affects its surface area and its volume.

In this activity, learners play a game and use pattern blocks to explore mirror images and reflection.

Wheels aren't the only things that can "roll" objects that are placed on top of it. Make non-intuitive shapes from cutouts and a compass to demonstrate this.

In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

See what force a magnet has on a wire that has current running through it: will it push it, pull it, or will nothing happen? This is the foundation of a simple electric motor.

In this activity, learners use cooperation and logical thinking to find solutions to network problems on the playground.

Make a cuíca (“kwee-ka”), a traditional Brazilian musical instrument that originated in Africa. Played primarily in Brazil, now you can play it at home, too, with this Exploratorium produced activity.

Listen to the beat of gravity. By taking two strings with weights tied to them at different, yet uniform intervals, you can hear the uniformity (and rhythm) of gravity's accelerating pull.

In this activity, leaners build their very own rainsticks, an instrument filled with pebbles and seeds that create sounds like falling rain. Save costs by using material found around the home.

In this activity, learners design unique tiles and make repeating patterns to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle.

In this activity, learners explore the properties of paper by constructing and modifying paper airplanes.

In this activity, learners explore Charles' Law in a syringe.

In this activity, learners construct three quick and simple mechanisms to start building a pop-up book. Learners fold, cut, and glue paper to make a bird beak, parallelogram, and V-fold.

In this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns.
