Seeing 3D
Source Institutions
Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!

See the World Through Color-Filtering Lenses
Source Institutions
In this activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.

Build a Giant Puzzle!
Source Institutions
In this activity, learners assemble large cubes to make nano-related images. Learners discover how different objects are related to nanoscience and nanotechnology.

Bending Light
Source Institutions
In this optics activity, learners make a lens and explore how the eye manipulates the light that enters it.
Guiding Light
Source Institutions
In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).
Why is the Sky Blue?
Source Institutions
In this activity, learners create a "mini sky" in a glass of water in a dark room.

Why is the Sky Blue?
Source Institutions
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.

Sun Prints
Source Institutions
This activity uses a special paper that can create images with exposure to the Sun. Collect objects of different shapes and sizes and use them to make interesting patterns on your sun print.

Pupil
Source Institutions
In this activity, learners explore their eye pupils and how they change.

Pinhole Magnifier
Source Institutions
In this activity related to light and perception, learners use a pinhole in an index card as a magnifying glass to help their eye focus on a nearby object.

Make a Prism
Source Institutions
In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

Critical Angle
Source Institutions
In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

Light and Sound
Source Institutions
In this four-part activity, learners explore light and sound through a variety of hands-on investigations.
