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

In this chemistry meets cooking activity, learners compare the stability of egg white foams with various additives.

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, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

This is an activity exploring color and color mixing.

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

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 visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

In this activity, learners investigate the basic crystal structures that metal atoms form.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.

In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.

Learners match puzzle pieces to outlines of a DNA strand. The puzzle pieces represent the four chemicals making up DNA base pairs: adenine, thymine, guanine, and cytosine.

In this demonstration, learners can observe a number of small convection cells generated from a mixture of aluminum powder and silicon oil on a hot plate.

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.

This activity (located on page 3 of the PDF under GPS: Lava Flow Activity) is a full inquiry investigation into the relationship between an object’s mass and the distance it is thrown by a catapult.

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

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 four-part activity, learners explore how the body works and the chemistry that happens inside living things.
