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)

In this lesson, students explore the cosmic microwave background to understand why a completely smooth (isotropic) background poses problems for the Universe we see today. Students will participate in an engagement activity which demonstrates how... (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 examine the idea of inflation in the Universe using rising raisin bread dough as a model for universal expansion. Students will read the Cosmic Times 1993 edition and use two articles: Pancake or Oatmeal Universe - What's... (View More)

This lesson uses a simple discrepant event to demonstrate the underlying cause for early miscalculation of the size of the Milky Way galaxy. By standardizing the Cepheid period-luminosity relationship without recognizing there were two types of... (View More)
