Building Tetrahedral Kites
Source Institutions
Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

Best Bubbles
Source Institutions
In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.

Free-Fall Bottles & Tubes
Source Institutions
In this physics activity, learners conduct two experiments to explore free-falling.

Pinhole Viewer
Source Institutions
In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

Terrestrial Hi-Lo Hunt
Source Institutions
In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.

Moisture Makers
Source Institutions
In this outdoor activity, learners compare the moisture released from different kinds of leaves and from different parts of the same leaf, by observing the color change of cobalt chloride paper.

The Thousand-Yard Model
Source Institutions
This is a classic exercise for visualizing the scale of the Solar System.

Rubber Band Racer
Source Institutions
In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

Rocket Wind Tunnel
Source Institutions
In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

Solar System in My Neighborhood
Source Institutions
In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

Where Does the Wind Blow?
Source Institutions
In this activity, learners investigate wind by comparing the force of wind in different locations. Learners build wind-o-meters out of wooden sticks and strips of paper.

Rain Machine (Solar Still)
Source Institutions
In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

Pitch, Roll and Yaw: The Three Axes of Rotation
Source Institutions
In this activity (page 87 of the PDF), learners move their bodies to better understand the three axes of rotation: pitch, roll and yaw.

A Spray Spree
Source Institutions
In this activity, learners explore water pressure by conducting an experiment with a garden hose. Learners build a testing apparatus and create PVC nozzles with different sized holes.

Super Soil
Source Institutions
In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.

Fishy Observations
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Rabbits), learners will visit a zoo, aquarium, or pet store to view a variety of fish.

Cool It
Source Institutions
In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

Colors in Nature
Source Institutions
In this activity, learners create colorful bead bracelets to wear outside while searching for matching colors in plants. Learners will be surprised by the variety of colors in nature.

Great Steamboat Race
Source Institutions
In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

The Old White Sheet Trick: Light and Insect Behavior
Source Institutions
In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.
