In this activity, learners explore and compare the buoyant properties of materials found in nature and in human-made materials.

Use geometry, a ruler, and a steady hand to create these amazing unfurling paper folds!

In this activity about osmosis, learners use a naked egg (one with a dissolved eggshell) to learn about selectively permeable membranes.

Learners build a model of a pollution control device--a cyclone. A cyclone works by whirling the polluted air in a circle and accumulating particles on the edges of the container.

In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.

In this activity, learners make flipbooks of drawings showing the progression of a Total Solar Eclipse.

In this math lesson, learners play a game to identify the properties of prime, composite, abundant, deficient and perfect numbers.

In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.

This is a demonstration you can use to show learners how valves and pumps work in concert to move blood through the circulatory system.

Learners listen to and try to decipher a radio message that was sent from Earth to possible intelligent civilizations.

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 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.
