For Ages 10 and Up

Glowing Water

This activity will show kids how light reflects and bends as it comes in contract with water.

EXPLORE
Homemade Spectroscope

Why wait for a rainy day to see a rainbow? Build your own spectrometer and you’ll not only see a rainbow, but you’ll also find out how they’re made!

EXPLORE
Why do things glow in the dark?

Have you ever had glow in the dark stars and planets on the ceiling in your room? How does it work? Why do the stars still glow after the lights are turned off?

EXPLORE
Glow in the Dark Jell-O

If you’ve ever wanted those glow in the dark stickers, you will love this activity! Kids will be able to learn about ultra violet light and florescence by making glow in the dark Jell-O!

EXPLORE
Why is the sky blue?

Contrary to popular belief, the sky is not blue because it reflects the ocean. Rather, light itself is being reflected. This activity help kids further understand that concept.

EXPLORE
Fluorescent Olive Oil

You may notice how water or other liquids tend to distort images when submerged. In this experiment, you will use oil and a laser to find out why this happens.

EXPLORE
Inverted Spoon

This activity will show how light interacts with mirrors through the use of water.

EXPLORE
Critical Angle

This experiment will help you understand the angle light makes during refraction.

EXPLORE
Lens Activity: Looking Through Lenses

A lens is a piece of transparent material typically with at least one curved surface, which refracts, or bends, light rays coming from an object. In this activity you will look at only two kinds of lenses, convex and concave, and observe their similarities and differences.

EXPLORE
Lose a Glass in a Glass

Use this activity to demonstrate the role of indexes of refraction in our ability to differentiate the appearance of different materials. Note: adult supervision is recommended for this activity because it involves paint thinner.

EXPLORE
Make a Light Fountain

Use this activity to illustrate light reflection, specifically total internal reflection, as well as how fiber optics work.

EXPLORE
Make a Telescope

This activity demonstrates how to make a simple telescope using two lenses and a cardboard tube.

EXPLORE
Mirrors and Images

What is it that lets us see objects? Some objects, such as the sun, give off their own light. Most objects, however, do not. These objects must reflect light in order to be seen.

Use Jell-O to make your own magnifying glass!
