In this activity, students are introduced to light and colored gels (filters). Students make and test predictions about light and color using gels; learn about the importance of gels (filters) to astronomers; then analyze images taken with regular... (View More)

In this activity, students build a photocell detector, and use it to detect different colors of light in a spectrum. Then they place the detector just outside the red region of the visible light spectrum and see that the detector detects the... (View More)

Learners will build an open spectrograph to calculate the angle the light is transmitted through a holographic diffraction grating. After finding the desired angles, the students will design their own spectrograph using the information learned. The... (View More)

This lesson provides a way for students to determine the relationship between the distance from a light source and its brightness. Once students discover the relationship, they can begin to understand how astronomers use this knowledge to determine... (View More)

Learners will use a spectrograph to gather data about light sources. Using the data they’ve collected, students are able to make comparisons between different light sources and make conjectures about the composition of a mystery light source. The... (View More)

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)

In this lesson, students examine the idea of inflation in the Universe using rising raisin bread dough as a model for universal expansion. Students will read the Cosmic Times 1993 edition and use two articles: Pancake or Oatmeal Universe - What's... (View More)

In this activity students are challenged to create a model of the universe in a single class period. This activity is designed to elicit student ideas and preconceptions about the contents and organization of the cosmos. Most students will be... (View More)

This activity uses Dr. Drake's framework to have students consider the implications of each term and make their own estimates of life in the Milky Way galaxy. This activity is part of a guide that was developed in conjunction with the Cosmic... (View More)

In this activity, students explore images taken with telescopes sensitive to several different wavelengths of the electromagnetic spectrum. Students compare the images to determine that light carries information about physical features in the... (View More)
