In this activity, learners of all ages can enjoy experimenting with ice. Try this experiment at the kitchen table or in the great outdoors to encourage budding scientists to experiment with ice.

In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.

In this activity (on pages 13-16 of the PDF) learners investigate three mystery samples to see which one contains life. The three samples are sand, sand and yeast, and sand and antacid.

In this activity, learners explore the possibilities of clay as a natural material.

In this project, students explore how levers work, by making a puppet with moving limbs.

Heat makes some materials expand, and it makes others shrink.

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

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

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

In this activity, learners design a therapeutic agent to image and/or cure various diseases in the respiratory system.

Learners will build and experiment with their own windmills made from simple household materials.

In this activity, learners of all ages will roll a ball coated with paint to artistically visualize the motion of the object.

This lesson gives full instructions for making cabbage juice indicator, a procedure sheet for learners to record observations as they use the indicator to test materials, and extension activities to d

Using a vertical wind tube and using simple materials, individuals and groups attempt to design a "satellite" that floats for at least 5 seconds.

Some animals can swallow food whole, but humans have to chew. In this activity, learners will investigate what saliva does chemically to food before we even swallow.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

In this activity, learners build water-propelled engines from soft drink cans.

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

In this crafty chemistry activity (on page 2 of the PDF), learners make their own paper from used paper they may have otherwise thrown away.
