This is a set of materials about spectroscopy, including a downloadable PowerPoint presentation and two demonstrations or activities. Learners will read and/or hear about the science of spectroscopy, what a spectrum is, and how spectroscopy is... (View More)

This demonstration allows students to visualize inversion in a fluid, explain it in terms of density, and apply the concept to weather systems and convection. Materials required include four Ehrlenmeyer flasks, two thin glass plates, a heat source,... (View More)

Audience: High school
Materials Cost: $5 - $10 per group of students

In this activity, students play a board game where they learn the characteristics of and differences between fission and fusion, as well as the real world applications of these energy-releasing reactions. Reproducible game cards and and game board... (View More)

In this learning assessment, students demonstrate understanding of the following concepts: solids, liquids and gases, changes of state, convection, and density. Students create a skit where the actors and actresses are molecules, and dramatize,... (View More)
