DSBK believes the sharing of resources between educators, parents, and the public alike is key to increasing our students' interest in and knowledge of science. On this page, you will find descriptions and links to astronomy activities developed and adapted by the volunteers of DSBK, which can be downloaded free of charge and used at home or in a classroom. Our volunteers have spent hours working to develop these activities so we kindly ask that you do not use them in a for-profit context without our express permission. If you would like an editable version of a document, please contact us.

Making Comets - Physical Model

The students (individually or in small groups) build a physical analog of a comet, including carbon dioxide and water ices, dirt (for silicates), household cleaner (for ammonia), and corn syrup (for complex organic materials). As the carbon dioxide sublimates, students can observe the processes of outgassing and jets that lead to comet tails. Can be adapted for all ages. For younger students or limited time/space, the instructor can build a single comet to show everyone else.


Impacts and Craters

As asteroids and comets make their way into the public consciousness, let your students explore the science of impacts and craters. Kids will make their own craters and test how different types of impactors affect crater formation. Appropriate for ages 7 and up.
