Build a Band
Source Institutions
In this design challenge activity, learners build a four-stringed instrument that can play a tune.

Turning the Air Upside Down: Convection Current Model
Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

Differing Densities: Fresh and Salt Water
Source Institutions
In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

Hoop Glider
Source Institutions
In this activity, learners will experiment with the physics of flight by making a gliding contraption with strange looking wings. The activity explores flight with connections to the natural world.

Pipes of Pan
Source Institutions
Create an instrument that you don't play--you just listen to it through tubes of various lengths.

Afterimage
Source Institutions
In this activity about vision and optical illusions, learners conduct a simple test to demonstrate how our eyes create "afterimages." Learners stare at a black cardboard bat for at least 30 seconds an
Fish Eyes: More than Meets the Eye
Source Institutions
In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

Going Green
Source Institutions
In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.

Diffusion & Osmosis with Data Analysis
Source Institutions
This three-part lab helps learners understand the essential principles governing diffusion and osmosis.

3D-ection: Molecular Shape Recognition
Source Institutions
In this activity (page 12), learners explore how molecules self-assemble and how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a comb

Color Table: Color your perception
Source Institutions
Look at pictures through different color filters and you'll see them in a new way. People have used color filters in beautiful photography or sending secret messages.

Spinning Tops
Source Institutions
Create your own spinning top, and explore color, shapes and spinning. This activity contains instructions for making your spinning top, and tips on how to design and decorate it.

Stem Cell Differentiation Game
Source Institutions
This game uses a modified Uno deck to review concepts related to stem cell research and diabetes.

A Universe Without Supernovae
Source Institutions
This fun and simple hands-on astronomy activity illustrates the value of supernovae in the universe.

Magic Disc
Source Institutions
In this activity, learners create an optical illusion by spinning two attached cups. A round ball seems to magically appear when the cups spin.
Balance Challenge
Source Institutions
In this quick activity, learners take a balance challenge to measure their average balance time. As they collect data, they investigate how practice and repetition improve their balance time.

Moving Model Glacier
Source Institutions
In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.

The Pressure's On
Source Institutions
In this chemistry activity, learners explore chemical reactions and their effects, including the kind of reaction in the human body that makes people burp!

Night Eyes
Source Institutions
In this outdoor, night-time activity, learners discover how to spot eye-shine (reflection of light from an animal's eyes) by using a flashlight to play a simulation game.

Radiohead
Source Institutions
When you teeth clatter, they make quite the racket disproportionately to how much they actually sound to someone else.
