This lithograph features an image from the Hubble Space Telescope, showcasing a colorful view of the star-forming nebula N90, located in the Small Magellanic Cloud. The accompanying activity, In Search of...the Electromagnetic Spectrum, is a... (View More)

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)

In this activity, students learn that infrared light is reflected in the same manner as visible light. Students align a series of mirrors so that they can turn on a TV with a remote control when the remote is not in a direct line with the TV. As a... (View More)

In this activity, students learn that light carries information. Students also discover that infrared (IR) radiation is a form of light that in some cases behaves like visible light and in other cases behaves very differently. For example, some... (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)

In this investigation, students use "point-source" light, light meters, and graphing software to quantify the reduction in light over distance. Through careful measurement of light received at several distances, students discover the best fit of the... (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)

This series of curriculum support materials and classroom activities explores how our understanding of the nature of the universe has changed during the past 100 years. Students examine the process of science through the stories of the people and... (View More)
