Explore the effects of gravity on a slowly falling object: a parachute you make out of plastic bags, string and stones.

Discover geometry by creating shapes from loops of paper. In this activity, paper loops transform to give you totally new structures when you cut them.

In this math activity, learners play a game similar to 20 Questions, in which learners must identify a secret number drawn from a bag.

In "Exploring the Universe: Exoplanet Transits," participants simulate one of the methods scientists use to discover planets orbiting distant stars.

The beautiful iridescent colors of a bubble in a can! With this Exploratorium Science Snack, create beautiful soap films on the open end of a can to see beautiful rainbows of color.

In this activity (12th on the page), learners investigate their ability to discriminate (see) different colors.

In this activity, learners will explore the insect life cycle by making a model.

In this activity, learners make a camouflaged butterfly to hide outside for others to find.

This demonstration activity models how Venus appears from Earth.

In "Exploring the Solar System: Stomp Rockets," participants learn about how some rockets carry science tools—not scientists—into space, and how a special kind of rocket called "sounding rockets" can

Testing magnets is always a fun pastime, but here, we're going beyond "will it attract the magnet?" In this activity, learners will investigate which materials allow magnetic fields to pass through or

Learners observe a bottle containing water and oil. They are invited to pick up the bottle and mix the contents together.

In this math game, learners throw dice and place the numbers in one of four boxes. Learners repeat this three more times and the learner with the largest four digit numbers is the winner.

Making liquids of different densities to perfectly lay on top of each other can be a frustrating exercise. The Exploratorium created this activity as a fool proof way of making a density column.

In this activity, learners will experiment with the physics of flight by making a gliding contraption with strange looking wings. The activity explores flight with connections to the natural world.

Create an instrument that you don't play--you just listen to it through tubes of various lengths.

In this version of a Sumo wrestling bout, players use mathematical skills to move their opponent's counter beyond the track and "out of the ring." Learners reveal playing cards and the player with the

Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.

In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

In this activity, learners recreate a method of detecting and correcting errors in computers called 'parity'.
