This is an activity to do when there is a solar eclipse!

Directed by instructional cards, learners kinesthetically model cell communication by acting as components in a cell signaling pathway.

In this activity, learners construct a paper glider to experiment with aerodynamic forces.

In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

Demonstrate the Bernoulli Principle using simple materials on a small or large scale.

In this hands-on activity, learners use heat to shrink samples of polystyrene plastic (#6 recycle code). Learners compare the size and shape of the plastic pieces before and after shrinking.

Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.

This activity demonstrates liquefaction, the process by which some soils lose their solidity during an earthquake.

It's difficult to see convection currents in any liquid that's undergoing a temperature change, but in this Exploratorium Science Snack, you can see the currents with the help of food coloring.

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 use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

In this activity, learners investigate sound wave science, in stereo! Learners construct a "stereo" out of a metal coat hanger and piece of string to explore sound vibrations.

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

In this optics activity, learners conduct an experiment to explore peripheral vision. Learners collect data about their ability to see shapes, colors, or letters using their peripheral vision.

In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.

In this engineering activity, challenge learners to construct a paper bridge that can support 100 pennies.

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 conduct an experiment to help Pharaoh design a better insulated tomb.

What causes frost to form on the outside of a cold container? In this activity, learners discover that liquid water can change states and freeze to become ice.
