Students are introduced to the basic properties, behavior and detection of black holes through a brief discussion of common conceptions and misconceptions of these exciting objects. They "act out" a way black holes might be detected through their... (View More)

Learners will relate the concept of density to the density of dust in space. They will use mission data from the Student Dust Counter (SDC) data viewer to determine the density of dust grains in a volume of space in order to answer questions... (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

In this activity, students compare two images of the Crab Nebula taken more than 40 years apart. By measuring the motion of some of the knots of glowing gas in the neubla, students will be able to determine the date of the supernova explosion that... (View More)

In this demonstration, a plastic soft drink bottle is used to demonstrate properties of gases and liquids with respect to temperature and pressure. Calculations using the formula for the Ideal Gas Law are included. The resource is from PUMAS -... (View More)

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)
