Learners draw pictures of how they envision scientists. By comparing and discussing the features in their pictures, they can discover common thoughts and stereotypes about scientists.

In this geology activity (page 6 of the PDF), learners explore how carbonic acid can slowly dissolve limestone and form caves.

In this activity about sleep rhythms (on page 21 of the PDF), learners will collect data about their own sleep cycles and use a fraction wheel to examine their data.

Learners will construct a model of a heart valve using a film canister, a piece of masking tape, and a piece of paper.

In this activity, learners play an active version of freeze tag based on predator/prey relationships.

In this activity, learners build mini-basketball courts using cardboard and measuring spoons. Use this activity to introduce learners to catapults, forces, and levers.

In this activity, learners will use household items to design and build an elevator that will carry 2 passengers to a height of 16 inches...or higher!

In this two-part activity about the connection between the lupine plant and butterflies, learners first read "Miss Rumphius," a storybook about lupine by Barbara Cooney.

In this activity, learners build a special rolling can that returns back to you when you push it forward. Use this activity to demonstrate the transfer of energy between kinetic and potential energy.

In this thought-provoking activity, learners plan a hypothetical project to build and operate wind turbines in their community.

Learners will explore the chemistry of mucous and its importance to our health by following a process to make their own replica "snot." The activity includes a time and age recommendation, a materials

In this chemistry activity, learners make indicator solution from red cabbage. Then, learners test everyday foods and household substances using the cabbage juice indicator.

Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

In this activity, learners explore different ways to stack cups to meet a personal goal.

In this activity, learners experiment with hydrogen peroxide, vinegar, yeast, and baking soda to produce hot and cold reactions. Use this activity to demonstrate exothermic and endothermic reactions.

In this activity, learners make plaster casts of an animal track to learn more about animals and animal behavior.

This game teaches ratio and proportion by having learners make "salads" that combine three types of beans in different combinations.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

In this activity, learners will explore trends in shark populations using shark landing data from the National Marine Fisheries Service.

In this chemistry activity, learners use common chemicals to produce carbon dioxide and observe its properties. This resource includes brief questions for learners to answer after the experiment.
