In this activity, caregivers and young learners work together to craft and talk about shapes and relative positions of such shapes by creating a mobile.

In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.

The goal of this activity is to design, build and test a house or toy for an animal.

In this activity, learners surprisingly pop balloons without touching them using orange peels. This Mr.

In this activity, learners will discover what colors are in different markers, and may be surprised at the results.

In this activity, learners explore the behavior of cold-blooded animals. Learners discover what happens when they change a fly's temperature.

In this activity, learners will investigate static electricity as they create waterless snow globes.

In this activity, learners use plastic tubing and a funnel to listen to their heart. Learners also discover that if they run around, their heart pumps harder and faster, making it easier to hear.

Learners mix vinegar and baking soda together in a bottle to create a chemical reaction. The reaction produces a gas, carbon dioxide, which inflates a balloon attached to the mouth of the bottle.

In this activity, learners will experiment with density and chemical reactions to create a flurry activity.

In this activity, learners experiment with the Stroop Effect by challenging themselves and others to try and read a list of colors as quickly and accurately as possible, with a twist.

In this activity, learners make their own edible DNA double helix out of candy and find out about the shape of DNA.

In this design challenge, leaners attempt to build a strong structure out of LEGO® bricks that can withstand a 4-foot drop.

In this activity, learners will construct a device to blow bubbles. By adding corn syrup to the bubble solution, we can increase the surface tension of the bubbles--and their size.

In this activity, learners turn empty 2-liter bottles into a see-through compost container.

In this activity, learners explore different types of fossils by making their out of dough and objects from around the house.

In this activity, learners will experience the different states of matter using crayons as the medium. Explore matter changing between phases while recycling old crayons.

Ancient trash tells archaeologists a lot about the past. In this activity, learners take a close look inside their trash can and think about the clues it offers about their lives.

In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.
