Convection Demonstration
Source Institutions
In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.
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.
A Universe Without Supernovae
Source Institutions
This fun and simple hands-on astronomy activity illustrates the value of supernovae in the universe.
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.
Design a Submarine
Source Institutions
Learners act as engineers and design mini submarines that move in the water like real submarines.
Static Water
Source Institutions
In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.
Shrinking Polymers
Source Institutions
In this activity, learners discover that some plastics will shrink when you get them hot. Learners bake polystyrene in a regular oven and discover what happens.
Floating Head Cup
Source Institutions
In this activity, learners watch a figure "magically" float up through the air.
How does the Atmosphere keep the Earth Warmer?
Source Institutions
In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.
Changing Colors
Source Institutions
In this challenge, learners have to figure out in what order to combine five solutions to change the color from clear, to yellow, to blue, and back to clear.
Sound Sandwich
Source Institutions
With a straw, two craft sticks, and some rubber bands, construct a noisemaker called a Sound Sandwich and explore how vibration produces sound.
pH Scale
Source Institutions
In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.
Trophy Triathlon
Source Institutions
In this activity, learners are challenged to design and construct a trophy for prize-winning sports equipment.
Sweat Spot
Source Institutions
In this activity, learners use a chemical reaction to visualize where moisture forms on the body.
Vocal Visualizer
Source Institutions
With a bit of PVC, a laser, a can/cup, and a small mirror, you can make a device that visualizes you voice or any sound transmitted into the cup/can.
Instant Ice
Source Institutions
In this activity, learners observe a quick phase change as water rapidly goes from a liquid state to a solid state.
How Many Pennies?
Source Institutions
In this activity (pages 13-14), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
Solar Energy
Source Institutions
In this activity (page 11 of PDF), learners compare the air pressure within a dark and a light bottle both heated by the sun, and discover that solar energy can be collected and stored in many ways
Masses & Springs
Source Institutions
In this online activity, learners use a realistic mass and spring laboratory. They hang masses from springs and adjust the spring stiffness and damping.
Soapy Boat
Source Institutions
Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.
