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)

In this lesson, students observe the surface of rotating potatoes to help them understand how astronomers can sometimes determine the shape of asteroids from variations in reflective brightness.

This is an activity about light. Learners will make their own spectroscopes from easily obtainable materials and use prisms to observe different types of white light sources to see the colors that form the visible light spectrum. This is Activity 2... (View More)

Audience: Informal education
Materials Cost: $5 - $10

This online repository includes captioned images designed to tell a story about the science of light. Developed for the United Nation's International Year of Light 2015 (IYL2015), the images showcase the incredible variety of light-based science... (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)

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

This is an activity about ultraviolet light. Learners will make ultraviolet light detector bracelets and use them to experiment with artificial light and sunlight. Then, they experiment with various sun-blocking materials to see how such materials... (View More)

Materials Cost: $5 - $10

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, learners will experiment with ultraviolet light sensitive plastic beads, which are generally white but turn colors when exposed to UV light. Participants are informed about the nature and risks of UV light and are asked to explore... (View More)
