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)

Students are introduced to the scientific tool of spectroscopy. They each build a simple spectroscope to examine the light from different light sources, particularly the Sun (Warning: Do not look directly at the Sun) and artificial lights (e.g.,... (View More)

In this activity, students are reminded that the Universe is made up of elements and that the heavier elements are created inside of a star, as they learned in the "Elements and You" activity. They are introduced to the life cycle of a star and to... (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)

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)

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 explore how eclipses happen and why Einstein needed a total eclipse to image stars near the Sun in order to demonstrate how the Sun's mass bends the light from a far away star. Using a foam ball and a lamp, learners create a... (View More)

In this lesson, students will read the 1919 edition of the Cosmic Times (see related resources) and respond by raising questions to be answered with further research. They will make a model of curved space to view the motion of spheres as explained... (View More)

In this lesson, learners will discover how certain snakes (pit-vipers) can find prey using a natural infrared sensor and will extend their understandings by exploring infrared technology applications. The lesson features background information for... (View More)

In this multi-day activity, students use infrared and visible images of animals and sort them into broad categories based upon the learner's own reasoning and observations of the images. Further explorations reveal that warm and cold-blooded animals... (View More)
