AstroEDU Activity of the Day

AstroEdu Banner all years

April 15 This classroom activity for high school students uses a collection of Hubble Space Telescope images of galaxies in the Coma Cluster. Students study galaxy classification and the evolution of galaxies in dense clustered environments. View the activity here.

April 14 Light pollution affects the visibility of stars. Building a simple Magnitude Reader, students determine the magnitude of stars and learn about limiting magnitude. View the activity here.

April 13 In this 30 to 45 minute activity, students (in teams of 4-5) experiment to create craters and learn about the landscape of the moon. The students make observations on how the size and mass, direction, and velocity of the projectile impacts the size and shape of the crater. View the activity here.

April 12 The Sun moves across the sky at an approximately constant rate because of the rotation of the Earth. By measuring how fast the Sun moves, you can work out how big the Sun appears in the sky. All you need are some household items and about 30 minutes on a sunny day. View the activity here.

April 11 Review the environmental factors that make the Earth habitable and compare them to other worlds within our Solar System. Use creative thinking to design an alien life form suited for specific environmental conditions on an extra-terrestrial world within our Solar System. View the activity here.
