More About This Resource...
Almost 14 billion years ago, our universe began in a cosmic explosion. What happened next? This comic strip, a supplement to the Hall of Meteorites Educator's Guide, uses text and images to explain the interactions that lead to the creation of stars, planetary nebulas, and supernovas.
- Text at the bottom of the page explains how this process occurs over and over, generating the building blocks for planets.
Supplement a study of astronomy with an activity drawn from this kid-friendly look at the formation of stars.
- Ask students what they know about the Big Bang. What did the explosion create, immediately and over time?
- Hand out copies of the Cosmic Chemistry comic strip.
- Have students focus on the final fact: Each new generation of stars contains higher concentrations of heavy elements than the previous generation. These heavy elements are the building blocks of the planet.
- As a class, ask students to speculate about the significance of this increase from generation to generation.
