Make a Speaker

In this activity, students will learn how an electromagnet works by making a simple one. Using this knowledge, students will design a diagram to make a working speaker using household materials. Then students will follow instructions on one method of making a speaker, and test their own designs to compare results.

Glowing in the Dark

In this activity, students will learn about phosphorescence and how certain materials can absorb and store energy from a light source. Students will use critical thinking skills to hypothesize which type of light -- incandescent, ultraviolet, infrared or fluorescent -- will produce the brightest glow from a glow-in-the-dark star. Students will perform an experiment using cameras to observe the intensity of the resulting glow from each type of light source.

Building A Solar House

Buildings that are called “green” or “environmentally sustainable” are designed to use energy as efficiently as possible. In Missouri, Washington University’s Tyson Living Learning Center achieves sustainability by incorporating green technologies in different ways, including the use of solar panels. In this activity, students will explore how solar panels work by building a simple circuit, a series circuit and a parallel circuit, using a solar panel to light a bulb and comparing which method yields the brightest light. Then students will build a solar-powered house using a shoebox, and test some variables to determine the most efficient way to harness solar energy to power a model home.

Explosive Science

In this activity, students will use household materials to investigate and explore how the release of carbon dioxide gas from a chemical reaction can cause a small-scale explosion. Students then will experiment with variables to determine which factors launch a film canister the highest.
