In this activity, learners investigate how some butterfly wings get their color.

In this activity about electricity and magnetism, learners discover how a doorbell works. A coil of wire with current flowing through it forms an electromagnet that acts similar to a bar magnet.

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

In this activity about flight, learners explore how high they can jump. Learners dip their finger in ink or dirt, then jump as high as they can and mark paper attached to the wall.

In this activity, learners make colored sugar and add it to water, alcohol, and oil to discover some interesting differences in dissolving.

In this activity, learners investigate the properties of graphene and graphite.

Learners build a yo-yo using a piece of wood, PVC pipe, and string. In doing so, learners explore the force of gravity and angular momentum.

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

In this experiment, learners test multiple food items to see if they are an acid or base using an indicator solution created with red cabbage.

In this activity, learners will explore how product barcodes are scanned accurately and be able to "guess" the last number in a 13 digit barcode correctly every time.

Did you know that a bullfrog can jump a distance of 10 times its body length? Learn more about nature's most acrobatic amphibian, the frog, through this set of short, hands-on activities.

Using indirect observational methods, learners distinguish between charged and uncharged objects.

In this outdoor, sensory activity, learners role play as animals trying to identify their "family's" scent and locate their "territory." Learners mark their territories and sniff out other territories

In this group activity, learners consider environmental conditions—temperature, presence of water, atmosphere, sunlight, and chemical composition—on planets and moons in our solar system to determine

In this activity on page 4 of the PDF (Behind the Scenes with Chemistry), learners make some special effects, including snow and breaking glass, with supplies found in the home.

In this quick activity (on page 2 of the PDF under GPS: Body Electricity Activity), learners will observe how dry breakfast cereal appears to dance when it gets close to a balloon charged with static

In this chemistry activity which should only be done under adult supervision (page 10 of the PDF), learners will create an exothermic process by making Sodium Acetate.

Build a house you can fit inside, using cardboard tubes.

In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.

By participating in a seed scavenger hunt, learners examine many adaptations of seeds, including how many seeds a plant makes, how those seeds travel to new locations, and what protects them from pred
