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

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 build unique sound enhancing inventions with items from around the house to amplify sound from their smart phone's speakers.

This is part 1 of the three-part "Crayon Rock Cycle" activity. In this activity, learners explore how sedimentary rocks form.

Use the Zoo Calendar (page 1 of PDF) to involve learners in interdisciplinary, whole language, and writing activities about ecological concepts.

In this activity, learners investigate the impact of oil pollution on the environment and wildlife. Learners use hard-boiled eggs and feathers to understand the damage that oil spills can cause.

Using indirect observational methods, learners distinguish between charged and uncharged objects.

In this chemistry activity which should only be done under adult supervision (page 10 of the PDF), learners will create an exothermic process by making Sodium Acetate.

In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

In this activity, learners construct cars that are powered by hand-made, electric propellers.

In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

Learners create beautiful fluid motion. They explore fluid dynamics, surface tension, solubility, and buoyancy while mixing liquids together.

In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.

In this activity on page 8 of the PDF, learners investigate vitamin C. Learners conduct a chemistry experiment to determine if Tang drink mix or orange juice contains more vitamin C.

In this activity about saturation (page 1 of PDF under SciGirls Activity: Sand Dunes), learners will build a series of sand castle towers using a 16 oz cup.

In this activity, learners create colorful bead bracelets to wear outside while searching for matching colors in plants. Learners will be surprised by the variety of colors in nature.

In this activity, learners explore sound by constructing their very own bagpipe instrument.

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

After a discussion about what a parachute is and how it works, learners create parachutes using different materials that they think will work best.

In this activity, learners design and build their own parachute using household materials with the goal of landing their passenger safely on a target.
