In this lesson, students will be introduced to how the Doppler effect changes our perception of wavelengths of sound (pitch) and light (color). Students will model how astronomers use the line spectra of stars to identify elements in the stars and... (View More)

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

In this lesson, students explore how eclipses happen and why Einstein needed a total eclipse to image stars near the Sun in order to demonstrate how the Sun's mass bends the light from a far away star. Using a foam ball and a lamp, learners create a... (View More)

Audience: Middle school
Materials Cost: $1 - $5 per group of students

In this lesson, students explore a discrepant event when they design an experiment to measure the rate that ice melts when in pure water versus salt water. It is designed to help students realize that a carefully-designed experiment may yield... (View More)

In this lesson, students will investigate the Doppler Effect and discover how the same principle can be used to identify a possible tornado in storm clouds and investigate the rotation of distant galaxies. Students should be familiar with the... (View More)

This is a set of materials about spectroscopy, including a downloadable PowerPoint presentation and other related resources. Learners will read and/or hear about the science of spectroscopy, what a spectrum is, and how spectroscopy is important to... (View More)

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)

Using weather data from both satellite and ground-based observations, this lesson challenges students to select a site location for a hypothetical mountain retreat. Students must determine and then justify a building site after gathering, graphing... (View More)

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)
