Coffee Filter Rainbows
Source Institutions
In this activity about color, learners get to explore the process of chromatography. Right before their eyes, they can watch ordinary green and black ink turn into a literal rainbow of colors.
What Causes Rainbows?
Source Institutions
In this activity, learners explore how and why rainbows form by creating rainbows in a variety of ways using simple materials. Learners create rainbows indoors and outdoors.
Light as Air
Source Institutions
In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.
Constellation Detective
Source Institutions
In this quick activity, learners practice locating a constellation in a map of very dark skies.
Spinning Your (Color) Wheels
Source Institutions
In this optics activity, learners use everyday materials to make a color wheel. When learners spin the wheel like a top, they will be surprised to see all the colors mixing together to appear white.
Observing the Moon
Source Institutions
Use this Moon Map Guide to help learners identify features on the Moon, while looking through a telescope.
Disappearing Glass Rods
Source Institutions
In this optics activity, learners discover how they can make glass objects "disappear." Learners submerge glass objects like stirring rods into a beaker of Wesson™ oil to explore how the principles of
Constellation Scope
Source Institutions
In this activity, young learners explore the basic shapes of constellations by making their own scope out of a cardboard tube and paper with pinpricks.
Why is the Sky Blue?
Source Institutions
In this activity, learners create a "mini sky" in a glass of water in a dark room.
Changing Colors
Source Institutions
Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.
Bubble Suspension
Source Institutions
In this activity, learners observe as soap bubbles float on a cushion of carbon dioxide gas. Learners blow bubbles into an aquarium filled with a slab of dry ice.
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.
Periscope
Source Institutions
In this activity, learners construct a device that allows them to look over ledges or around corners.
Rainbow Film
Source Institutions
In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.
Bring it into Focus
Source Institutions
In this activity (page 2 of PDF), learners play with a lens and a piece of paper to focus an image on the paper. Learners look at different things, and see how the lenses affect the image.
Safe in the Sun
Source Institutions
In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.
Diet Light
Source Institutions
In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.
Exploring Earth: Investigating Clouds
Source Institutions
“Exploring Earth: Investigating Clouds” is a hands-on activity in which visitors create a cloud in a bottle and explore it with laser light.
Glow Fast, Glow Slow: Alter the Rate of a Reaction!
Source Institutions
Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold water.
Tissue Paper Spray Art
Source Institutions
In this activity, learners observe color mixing and absorbency using colored tissue paper and spray bottles.
