During this activity, learners will make different versions of "ooze" using varied proportions of detergent and glue.

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

In this activity learners will explore how water moves on waxed paper. Learners will use science process skills such as using tools and making observations as they explore surface tension.

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

Create gas with a glass of water, some wire, conductors and a battery! You will be separating water (H2O) into oxygen and hydrogen.

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.

In this activity learners will "rescue" animals from tape and then sort the animals. Learners will use science process skills such as categorizing and making observations while they play.

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, learners create slime to model mucus and examine how it collects simulated particles. Mucus keeps particles from the environment out of our lungs when we breathe.

This is an activity exploring color and color mixing.

In this quick activity (located on page 2 of the PDF under GPS Wetlands Activity), learners will model how wetlands act as natural filters for the environment.

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 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 fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

In this quick activity (page 2 of PDF), learners will play a game using their observation and listening skills, interpreting clues from each other to deduce their secret animal identity.

In this activity, learners are challenged to design and construct a trophy for prize-winning sports equipment.

In this activity, learn about the cultural stories behind constellations. Then recreate your favorite constellations using marshmallows and toothpicks.

In this activity (pages 13-14), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

In this chemistry challenge, learners work to figure out which of four juices are real, and which is just food coloring and sugar.
