In this activity, learners use a straight line to learn about circles. Learners measure and record the diameter and circumference of different sized cylindrical objects on a chart.

Yes, you can weigh your car by figuring out your wheel's tire pressure combined with the "tire's footprint." You'll need someone with a car, driver's license, and safety in mind.

In this calculus activity, learners use a classic problem of geometrical probability to find an important mathematical constant (pi).

In this activity, learners explore a surprising method for calculating the mathematical constant pi, known as Buffon's Needle.

In this activity, learners use food scraps from the kitchen to grow new vegetables.

In this optics activity, demonstrate diffraction using a candle or a small bright flashlight bulb and a slide made with two pencils.

With a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink.

In this activity, learners explore how different deodorants work. Learners treat agar plates with different types of deodorants and compare the bacteria growth on the plates to the control sample.

Challenge popular misconceptions, learners explore how a mirror actually reflects an image in this activity.

In this activity, learners explore motion and airflow by setting two aluminum cans on their side and blowing air in-between them.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this physics activity, learners construct a small-scale version of a classic carnival game.

In this activity, learners make their own heat waves in an aquarium.

This activity guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.

In this activity, learners follow simple directions to explore and create platonic solids.

In this activity, learners make a photographic image—without a camera!

In this activity, learners build a tool called an inclinometer that can find the height of any distant object, from a tree to the North Star.

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

To understand how skaters turn in midair, try this little experiment! Individuals can do this activity alone, but it works better with a partner.

In this activity about osmosis, learners use a naked egg (one with a dissolved eggshell) to learn about selectively permeable membranes.
