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.

Make Your Own Barometer
Source Institutions
In this weather activity (page 10 of the PDF), learners will demonstrate the changes in atmospheric pressure by constructing their own barometer.

Ready to Observe: Enhance Your Telescope Experience
Source Institutions
This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

Seeing in the Dark
Source Institutions
In this activity (17th on the page), learners investigate why you cannot see colors in dim light.

Cleaning Air with Balloons
Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

Magnet Powered Pinwheel
Source Institutions
Learners use the current flowing in a wire to create a magnetic field that turns a magnet. Learners can use this property of electromagnetism to build a magnet-powered pinwheel.

Thaumatrope
Source Institutions
In this activity, learners make an optical illusion toy from the 1800s to explore persistence of vision.

Cave in a Cup
Source Institutions
In this activity (page 2 of PDF under GPS: Cave Swallows Activity), learners will model how caves are formed by placing one piece of chalk in a cup of vinegar and another piece in a cup of water, then

Static Cling
Source Institutions
In this activity, learners investigate static electricity using everyday objects at four different stations.

Soap Bubble Art
Source Institutions
Capture soap bubble patterns on paper! In this activity, learners can create beautiful pictures from popping soap bubbles.

Exploring Properties: Surface Area
Source Institutions
This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

Balloon Drive
Source Institutions
In this challenge, learners make a helium balloon hover in one spot and then move it through an obstacle course using air currents.

Stretching Wires
Source Institutions
In this activity, learners determine the elastic and plastic properties of different types of metal wires.

Atmosphere Composition Model
Source Institutions
In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

Salt Crystal Garden
Source Institutions
In this activity, learners will explore saturated solutions and discover how crystals form.

Density Rainbows
Source Institutions
In this activity, learners explore the concept of density by pouring 5 different liquids into a jar. Food coloring is added if needed to give each liquid a distinct color.

3D-tection: Trying to Fit In
Source Institutions
In this activity, learners explore how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a combined unit.

Find the Best Way to Clean Oil off Bird Feathers
Source Institutions
In this experiment, learners examine the way oil affects bird feathers and test different cleanup methods to find out which works best.

Spin Art
Source Institutions
Make your own spin art device using an old record player! Notice patterns and effects the spinning movement has on your work. When finished, post your work to the Spin Art Gallery!
