Darcy kicked off our space unit by creating a comet in our classroom! A comet is sometimes called a dirty snowball or an icy mud ball flying through space.  It is a mixture of water, frozen gases, and dust. Comets are known for their dust “tails” which are seen as they fly closer to the sun and begin to melt.

Darcy combined dirt, ammonia, water, corn syrup (organic material) and frozen ice (very exciting) to make our comet. We observed it melt throughout the day. I know the children have a wonderful visual of what a comet looks like after this experiment.
