In this activity on page 14 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners turn plain pieces of recycled plastic into shrunken works of art.

In this biology experiment, learners plant soybean seeds in plaster of Paris, witnessing firsthand the mighty power and ability of plants to grow in adverse conditions.

No glue is needed for learners of any age to become marshmallow architects or engineers.

See and hear how sound waves travel through different types of materials. Extend the experiment online and learn how you can "see" with sound waves using ultrasound.

In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

In this activity, learners create a kind of balance device using a wire coat hanger, some string, and paper cups.

In this activity, learners surprise their eyes with an optical illusion involving arrows made out of pipe cleaners.

Make a quick and easy filter from household materials. A filter will catch any solids suspended in a liquid and filter them out. By using a filter, learners can discover amazing things.

In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

In this activity, learners create a straw oboe to explore sound and pitch.

In this activity, learners explore density and buoyancy as they design and construct rafts.

How do you measure a bubble when it's floating? You can't really, but in this activity, learners can measure the diameter of the ring of suds a bubble leaves on a flat surface.

In this activity, learners make film canister rocket ships. A fin pattern is glued onto the outside of the canister, and fuel (water and half an antacid tablet) is mixed inside the canister.

In this demonstration, learners will be "wowed" as three matches burn to form a triangular pyramid shape and "magically" rise off the table.

In this simple activity (on page 7 of the PDF), learners use water and liquid dish detergent to see which one removes lipstick better from an index card.

This is a classic exercise for visualizing the scale of the Solar System.

In this activity related to light and perception, learners use a pinhole in an index card as a magnifying glass to help their eye focus on a nearby object.

In this activity, learners use a simple trick of perspective to dress friends in tiny cutout clothing. Learners make tiny pants out of card stock and tape them to the end of a stick.

In this activity, learners make their own rock candy. Crystals will grow from a piece of string hanging in a cup of sugar water. The edible crystals may take up to a week to form.
