Students are introduced to the periodic table and the concept of atomic elements. The group discusses how all material in the Universe is composed of elements and that the atom is the smallest particle that still has the physical and chemical... (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)

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 be introduced to how the Doppler effect changes our perception of wavelengths of sound (pitch) and light (color). Students will model how astronomers use the line spectra of stars to identify elements in the stars and... (View More)

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

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 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 the discoveries that caused... (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)

Audience: Middle school
Materials Cost: $1 - $5 per group of students

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)
