In this activity, learners will create glitter bottles with adult supervision. These are a fun way for little ones to practice observing and making comparisons.

In this activity, learners will conduct an experiment to discover methods of reventing foot mold growth on food.

In this activity, learners will make fish cutouts that propel through the water with the help of surface tension.

In this activity, learners construct a device that allows them to look over ledges or around corners.

In this activity, learners will observe magnetic properties and sort objects by them. This activity uses everyday items to teach learners about magnetic forces, poles and properties of magnets.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

In this activity, learners explore what makes a boat float and sink. They examine and test various objects to determine why objects float or sink.

In this activity, learners create a sound visualizer from common materials to help see the vibrations created by sound. Sounds from a tone generator make salt dance on a vibrating balloon membrane.

In this activity (located on page 3 of the PDF), learners investigate the way water moves and how we can control and direct water.

Everybody loves bubbles, and this is the best bubble recipe ever!

In this fascinating and fun experiment, learners use chemistry to identify a mystery powder and to solve a "crime," a process similar to that used by real forensic scientists.

In this activity, learners make an electroscope out of a foam cup, straw, aluminum pie pan, thread, and foil. Learners use their electroscopes to test for static electricity.

In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.

In this activity, learners build a switch to turn electrical circuits on and off.

In this activity learners will build roller coasters and test them using small balls or marbles.

In this activity, learners build their own sound machines and explore the interplay of motion and sound.

In this activity, learners create air cannons out of everyday materials. Learners use their air cannons to investigate air as a force and air pressure.

In this activity, learners explore sound by constructing tube zithers, stringed instruments from Southeast Asia and the South Pacific.

In this activity, learners build a water squirter using a PVC pipe, dowel, and foam. This activity is great for the summer time and introduces learners to forces and water pressure.

Learners observe and compare the sizes of three toy “growing” crocodiles made from water-absorbent polymers. One is it its original state, dry, hard, and about 10cm long.
