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 activity demonstrates Newton’s Second Law (F=ma), and helps show the relationship between potential and kinetic energy. Students sit on a skateboard in a sling shot configuration, and are accelerated down the hall. Potential energy from the... (View More)

Audience: High school
Materials Cost: Over $20 per group of students

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 lesson, students are introduced to the electromagnetic spectrum. They observe a demonstration of the visible light spectrum created by a flashlight and a prism, complete an activity sheet where they identify the wavelength that is involved... (View More)

This is a hands-on lab activity about seawater density, specifically the relationship between density of fluid, weight of an object, and buoyancy. Learners will develop hypotheses and observe a demonstration of density to understand its role in... (View More)

In this demonstration, evidence of the Earth's rotation is observed. A tripod, swiveling desk chair, fishing line and pendulum bob (e.g., fishing weight or plumb bob) are required for the demonstration. This resource is from PUMAS - Practical Uses... (View More)

This is a lesson about discovering distant planets using an Earth-based observing technique called stellar occultation. Learners will explore how a stellar occultation occurs, how planetary atmospheres can be discovered, and how planetary diameters... (View More)

This activity introduces students to the visible light spectrum, and demonstrates what happens to the appearance of an image when certain wavelengths of light are blocked by filters or made visible using special tools. Students are lead through... (View More)

This experimental activity is designed to develop a basic understanding of the interrelationship between temperature and pressure and the structure of a device made to examine this relationship. Resources needed to conduct this activity include two... (View More)

In this demonstration, students detect the interference of waves and measure wave phenomena using an experimental apparatus consisting of a laser pointer, a second surface mirror scrap (like a bathroom mirror) binder clips, razor blade, ruler, and a... (View More)
