What causes dilated pupils? Young scientists will find out by applying what they already know about changes in pupil size and making models of the pupil.
Understanding absorption means understanding why certain fibers and materials can absorb water! Kids will see absorption in action in this simple project.
The buoyant force of water explains why some objects float in water. But why do some objects sink? Find out in this physics experiment and learn about density.
With this cool floating rocks project, your child will get some hands-on experience with buoyancy and learn why certain rocks like pumice are able to float.
You've heard all about oil spills, but can they really be that bad? After all, vegetable oil is in almost every yummy baking good from cookies to brownies.
Learn how to make a hygrometer to measure relative humidity in this project. Make a sling psychrometer hygrometer with gauze, thermometers, and a bottle.
Determine if certain colors of light are more effective for photosynthesis. Plant seeds in cardboard boxes with different light, record visible growth.
In this project, build an insect model that shows how the head, thorax, and abdomen fit together! Learn insect anatomy by constructing a paper mache critter.
What does a raindrop look like when it splashes on the ground? Is each raindrop unique like snowflakes? Find out how raindrop size varies in this experiment.
Young physicists will wrestle with a discrepant event: the Hammer Ruler Trick. They'll make some inferences about torque, balance, and center of gravity.
