Coma Cluster of Galaxies
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.
How Light Pollution Affects the Stars: Magnitude Readers
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.
Snakes & Ladders Game
April 13 The classic snakes and ladders game is replaced by rockets and comets in this astronomy themed version. The game is challenging and interactive way to learn various astronomical objects while moving your way to the winning square as space travellers. View the activity here.
Model of a Black Hole
April 12 Many children may have heard of black holes and already have the understanding that they are ‘bottomless wells'. If something falls into a black hole, it is impossible for it to escape—even light cannot escape and is swallowed. The lack of light is how black holes get their name. These objects are mysterious and interesting, but they are not easy to explain. This activity will allow children to visualize, and therefore help them decompose, the concepts of space-time and gravity, which are integral to understanding these appealing objects.

Lunar Landscape
April 11 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.
