Learners will look at various light sources (including glow sticks and Christmas lights) and make conjectures about their composition. The activity is part of Project Spectra, a science and engineering program for middle-high school students,... (View More)

Learners will build and decorate their own spectrographs using simple materials and holographic diffraction gratings. After building the spectrographs, they observe the spectra of different light sources. Requires advance preparation to spray-paint... (View More)

Learners will explore different ways of displaying visual spectra, including colored "barcode" spectra, like those produced by a diffraction grating, and line plots displaying intensity versus color, or wavelength. Students learn that a diffraction... (View More)

In this lesson, students explore the cosmic microwave background to understand why it permeates the universe and why it peaks as microwave radiation. Students should be able to explain that the origin of the background radiation is the uniform... (View More)

In this lesson, students will explore the density of substances as a model for understanding the mass to light ratio as a predictor of dark matter. They will measure and calculate mass and volume to calculate the density of a foam ball. Students... (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)

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)

The purpose of this lesson is to model for students gravitational waves and how they are created. Students will build a simple "Gravitational Wave Demonstrator" using inexpensive materials (plastic wrap, plastic cups, water, food coloring, and... (View More)

Audience: High school
Materials Cost: $1 - $5

In this lesson, students simulate an experiment in which the discovery of dark energy can be made by plotting modern supernova distances on a Hubble Diagram. Data is provided in an Excel spreadsheet (see related resources). In order to complete this... (View More)

Audience: High school
Materials Cost: Free

In this lesson, students measure the size of several galaxies to reproduce a plot of Hubble's Law. The goal of this lesson is to give students the chance to simulate the process that led to the notion that the universe is expanding, provide insight... (View More)
