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)

In this activity, students will discover how mass is distributed in the solar system and a galaxy by using kitty litter. Students compare the distribution of mass in a solar system to the distribution of mass in a galaxy. This is Activity 6a in the... (View More)

In this activity, students use Newton's Laws of Motion, and the motions of the planets, to determine the mass of the sun. They then use the same techniques to determine the mass of a galaxy. In doing so, students convert among different units of... (View More)

In this activity, students match unusual galaxies with their distinctive names and justify their reasoning. Students discover that often, galaxies acquire their names based upon how they appear to observers. This activity includes a student... (View More)

In this activity, students estimate the size of the visible universe in relation to the size of the Milky Way Galaxy. To do so, students will get a sense of scale and will convert from centimeters to kilometers. This is the first activity in the... (View More)
