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)

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

In this lesson, students will read about and research the major historical events that occurred throughout the year 1919. They will use different readings and articles to understand and describe what life was like during this time. In addition, the... (View More)

Audience: Middle school, High school
Materials Cost: Free

In this investigation, students use "point-source" light, light meters, and graphing software to quantify the reduction in light over distance. Through careful measurement of light received at several distances, students discover the best fit of the... (View More)

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

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)

Materials Cost: Over $20 per group of students

In this lesson, students identify and describe unfamiliar scientist heroes who contributed to the field of science until the year 1929. Students create a T-square graphic organizer about a specific group of women scientists of the Harvard College... (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)

In this lesson, students consider observations and inferences to determine the support for each of two theories on the origin of the universe: Steady State and Big Bang. Working with partners, students draw from a set of Evidence cards (master is... (View More)

In this lesson, students create a fictional narrative on the beginning of time. They use their scientific knowledge of the Big Bang Theory and go back into time to when it occurred so they can make observations about it. Students can select from... (View More)

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 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)
