While each comet has its own unique chemical signature, most of them contain water ice, organic compounds, dust, and rocky or stony chunks. Transcript: Music: Theme We're going to learn about how to make a comet model from various craft items, an activity you could do in the classroom or an afterschool or at home on your own or even as part of a science camp. It's fun to make your own comet and expose it to a simulated solar wind to observe its behavior. Overview In this activity, students will learn the basic characteristics of a comet and older students will practice evaluation and improvement of their comet models.
