  • Sensational Sound 

    Afterschool Resource

    Sound travels—not just through air, but through liquids and solids, too. Your group will listen to a hanger clanged against a table. Then they’ll put their ear to something attached to the hanger to realize that the clanging sound travels through solids, too.

  • Falling for Gravity 

    Afterschool Resource

    Your group will watch various objects (pens, pennies, erasers, etc.) fall from the same height to see if they reach the ground at the same time. They also will roll marbles down an inclined plane to see if they reach the bottom at the same time.

  • Geyser Riser 

    Afterschool Resource

    In this experiment, your group will create pressure in a bottle to reenact one of the special conditions under which a geyser erupts. A geyser is a hot spring that shoots a column of hot water into the air. Your group will make a model geyser using liquid soap, a bottle, and Alka-Seltzer® tablets.

  • Cool Idea 

    Afterschool Resource

    Water and salt can make for some great basic chemistry activities. Your group will see what happens to water and ice when a little salt gets thrown into the mix. Note: part of this activity shows results one day later. As an alternative, you can have the kids prepare the cups of water ahead of time, perhaps at the end of the day before you do this activity (see steps 3 and 4 below).

  • Balancing Points 

    Afterschool Resource

    Balance is a fun concept to play with. By constructing models, your group will learn that putting heavier objects closer to the center and lighter objects farther from the center is one way to find a balance.

  • By the Light of the Moon 

    Afterschool Resource

    As the moon goes through its phases, it looks a little different each night, ranging from not there at all to full. Your group will act out how the sun illuminates the moon as it orbits Earth, to understand how the moon moves through its phases.

  • Dances with Bees 

    Afterschool Resource

    Honeybees communicate with sophisticated “dances” to tell other bees where to find nectar and pollen. Your group will reenact a couple of these dances to learn about bees and how they communicate with each other.

  • Fun with Forces 

    Afterschool Resource

    Almost any place can become a “lab” for exploring forces. Your group is going to experiment with the force they feel when pressed against the side of a car that is going around a curve really fast. They’ll explore a similar situation, an object that stays in a mini-bucket as it is swung overhead.
