Creating a Comet
Seventh-graders in Kristin Suer’s earth science class created their own comet! Suer demonstrated how to make a comet using dry ice, sand, and cornstarch as part of their Space Unit. The ingredients all represented things that make up a real-life comet and its structure was discussed in detail. They made observations about the changing states of matter and how its mass changed rapidly due to the “Solar Wind” that was reenacted with a hair dryer.
