Learners add calcium chloride to a baking soda solution and observe an increase in temperature along with the production of a gas and a white precipitate. These are all signs of a chemical reaction.

In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.

In this hands-on nature activity, learners observe the emergence of leaves and flowers. Branches from trees and bushes are collected in the early spring, brought indoors, and placed in water.

In this environmental engineering activity, learners build windmills using everyday items. The first challenge is to build windmills that spin when placed in front of a fan.

This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour

In this activity, learners investigate the food, water, and space needs of common livestock animals.

This activity (on page 2 of the PDF under SciGirls Activity: Soccer Ball Kick) is a full inquiry investigation into transfer of motion.

In this activity, learners explore the relative sizes and distances of objects in the solar system.

In this activity, learners explore the potential of interchangeable standard parts to create a large number of unique creations in different combinations.

Learners mix vinegar and baking soda to produce a gas. With the addition of a bit of liquid soap, the gas becomes trapped in measurable bubbles.

This is a quick game about self-assembly (page 2 of PDF under Self-Assembly Activity). Like the molecules of DNA, learners will self-assemble into a pattern by following a simple set of rules.

In this math activity, learners role-play as wait staff at the Kidtropolis Diner. It's the end of the night and it's time for the staff to collect their tips.

What is the optimal environment for hatching brine shrimp? Using a scaffold, learners design and conduct experiments testing the effect of a single abiotic factor on brine shrimp cyst hatch rate.

In this genetics activity, learners create imaginary creatures known as "Reebops" to explore the relationships between genes and inherited traits.

In this activity, learners use earthworms as "unknown creatures" from the South American jungle to find out how animals use senses.

In this activity, learners build scaled-down structures and cantilevers in a series of "building out" challenges with bamboo skewers and tape.

A group of learners simulates the spread of disease by trading slips of paper, one set of which has been treated with a baking soda solution.

In this activity, learners explore the great pump in their chests--the human heart!

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.

Learners will explore the scientific mystery behind a disappearing group of trees by examining data and attempting to explain the decline.
