In this activity, learners explore how engineers work in a team to solve problems.

In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.

In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.

In this activity, learners will experiment with salt and ice in order to turn a bag of ingredients into ice cream.

This experiment describes how to create a "dribble bottle" which only leaks water when the cap is unscrewed. The full water bottle has a small hole made with a push pin.

In "Chemistry Makes Scents," participants use their noses to distinguish between chemicals with very similar structures.

In this activity, learners use chemistry to produce weathered "antiqued" paper with burned edges. Learners first soak white paper in coffee and then apply a charring solution of ammonium chloride.

Learners use chromatography to separate and analyze the mixture of pigments in leaves. Use this activity to discuss photosynthesis as well as why leaves change color in autumn.

Learners use filter paper and water to analyze six different markers. They mark the paper with ink, and dip the paper in water. The water travels up the paper and dissolved ink travels with it.

In this activity, learners find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

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, learners will create their own bubble solution. Learners will explore chemistry, geometry and trial and error through this activity.

Learners make slime from white school glue and Borax detergent. The long chain molecules of the white glue become cross-linked by the Borax into a big network.

In this activity, learners will practice writing while making a fun messy craft. Learners will explore texture and color as well as develop writing and fine motor skills through this activity.

Learners add drops of alginate solution to a solution of calcium chloride. The alginate does not mix with the calcium chloride, but forms soft gel beads.

Learners press their fingertip onto a clean Plexiglas sheet. The fingerprints are then revealed as learners dust over the print with fingerprint powder.

This activity features two connected hands-on activities about dinosaur bones.

"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form.

"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?
