Pictures From Light
Source Institutions
Did you know that using a lens one can bend light to make pictures of the world? It's true!
Transparent Gelatin
Source Institutions
In this optics activity, learners explore how they can make gelatin stop light, but not stop them from seeing fruit suspended within.

Color Vision
Source Institutions
In this online activity, learners make a whole rainbow by mixing red, green, and blue light. They can change the wavelength of a monochromatic beam or they can filter white light.

Bubbularium: See the Colors in Bubbles
Source Institutions
With little more than a flashlight, a straw, and a plastic lid, make an observatory so you can see the amazing colors in bubbles.

Paper Whites
Source Institutions
Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.

Glowing in the Dark
Source Institutions
In this activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.

Spectroscope
Source Institutions
In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

Light and Sound
Source Institutions
In this four-part activity, learners explore light and sound through a variety of hands-on investigations.
The Bent Pencil
Source Institutions
In this optics activity, learners explore how light bends and affects what we see.

Make Money Appear Before Your Eyes
Source Institutions
In this optics activity, learners use water to make a coin "appear" and "disappear." Use this activity to demonstrate how light refracts and introduce light as waves.
Light on Other Planets
Source Institutions
In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

Night Lights
Source Institutions
In this activity, learners create night lights using a plastic cup, programmable PICO Cricket, tri-color LED, and sensor.

Three Colors of Light
Source Institutions
Have fun with additive mixing! Observe what happens when the three primary colors of light--red, green and blue--are mixed together, resulting in white light.

What is Light?
Source Institutions
In this four-part activity, learners will discover the exciting world of light--the most important form of energy in our world--and be able to identify and describe different types of light.

Colored Shadows Investigation
Source Institutions
This activity (located on page 3 of the PDF under GPS: Light and Color Activity) is a full inquiry investigation into mixing colors with light.

Make a UV Detector
Source Institutions
In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

See the Light
Source Institutions
Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

Laser Jello
Source Institutions
In this activity, learners use gelatin as a lens to investigate the properties of laser light.

Make a Light Fountain
Source Institutions
In this optics activity, learners make a "light fountain" from a clear plastic bottle, flashlight, and other simple materials.

Polarized Light Mosaic
Source Institutions
In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required
