Towel Testing

Ingredients in your shampoo are toxic enough to kill plants. The 16th installment of the series of 24 tests the toxicity level of various concentrations of SLS, a chemical found in nearly all shampoo. Learners prepare percent solutions...

Students demonstrate the scientific method by conducting an ice cube melting experiment. They make predictions and observations, and conclude what factors make ice melt more slowly or quickly than normal.

Storing food in plastic makes more sense than storing it in paper. Young learners research the properties of these materials along with aluminum foil. They then connect the properties of the materials to their usefulness by completing a...

Two activities are included in this resource. In the first, junior geologists model sedimentary rock layers, apply the Law of Superposition, and demonstrate folding and faulting of the Earth's crust. The model is technically a sandwich....

Take foldables to all new heights. Pupils build and fly different types of paper airplanes in the 14th portion of a 22-part unit on aviation. Groups collect data on distance and flight time for each plane and compare the data from the...

Scholars collect data from heating sand and water before forming testable hypotheses about why sand heats up faster. Afterward, they develop and run experiments to test their hypotheses.

Mirror, mirror, on the wall ... who's the best chemistry teacher of them all? You'll get the vote for certain after your class completes the Silver Mirror experiment! Partnered pupils use Tollen's reagent and glucose to silverplate a...

Let's go fly a kite ... oops, a paper airplane! The 13th segment in an aviation unit of 22 relates the parts of an airplane to paper airplanes. Pupils learn the functions of the control surfaces of a plane to really make their knowledge...

Watch as the MythBusters team put the famous myth that you can't fold paper any more than seven times to the test. [3:53]

In this video segment adapted from ZOOM, cast members make a bridge from a single piece of paper. Will it be strong enough to hold a hundred pennies? [3:41]
