Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

In this activity/demo, learners are introduced to the connection between medieval stained glass artisans and nanotechnology.

In this activity, learners will explore the ways natural materials can produce sounds. Appropriate for any age, learners can make individual music or create a symphony with others.

Everybody loves boomerangs! In this activity about force and motion, the learners will experiment with boomerangs and explore how they work. This is a great activity to get learners up and moving.

In this activity, learners will dip different items in paint and then roll those items down a ramp. Learners will use science process skills such as observations and experimenting.

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

In this activity learners will investigate magnetic and non-magnetic items in a sensory bottle.

In this activity, learners will construct a device to blow bubbles. By adding corn syrup to the bubble solution, we can increase the surface tension of the bubbles--and their size.

To understand how skaters turn in midair, try this little experiment! Individuals can do this activity alone, but it works better with a partner.

In this activity, learners will put together towers using building bricks, then take the tower apart and challenge themselves to use the same bricks used to build a bridge.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

In this activity, learners will use bubble wrap to print patterns on paper and experiment with mixing colors.

In this activity, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.

This is a simple and fun activity for learners to explore water and colors.

In this fun activity about spiders, learners build and design a spider from cardstock, straw, string, and pipe cleaners.

In this activity, learners thread gumdrops together to make a model of a polymer.

In this activity, learners use pattern blocks and mirrors to explore symmetry. Learners work in pairs and build mirror images of each other's designs.

In this activity, learners will write a secret message that only their friends will be able to read.

This hands-on activity shows you how to make a shaker -- a small instrument with a big sound! Fill it with beads or even pennies for a cool sound.

In this activity, learners will construct an air cannon as a model for the human ear.
