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.

In this health and fitness activity, learners focus on the importance of daily physical activity, specifically walking.

In this activity, learners will use cereal to conduct an experiment and investigate how decreased bone density is related to increased risk of bone fracture.

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 hands-on activity, learners explore static electricity through the use of common household products. They also explore the connection between static electricity and cold weather.

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.

In this "Sid the Science Kid" activity, learners set up a simple experiment to find out how sunscreen counteracts the effects of the sun.

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 make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction.

En esta actividad, los aprendices experimentarán con las tres fases del agua. Intentarán controlar la rapidez de los cambios de estado al manipular la temperatura y la presión del agua, hielo, y gas.

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.

In this outdoor activity, learners first explore lizard feeding behavior by creating a "lizard rig" to dangle different objects in front of live lizards and see which objects the lizards try to bite.

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

In this activity, learners make critters out of recyclables and apply the rules of mathematics to solve genetics problems.

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 make a small batch of biodiesel that will work in any diesel engine. Learners use an old juice bottle as a "reactor" vessel to chemically process vegetable oil into fuel.

In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.

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