2-22-19 Gum

This week we did a project on gum. We had to know if the gum would increase or decrease in mass over time while being chewed, which means would it get bigger or smaller over time while being chewed. My friend Maddiem2021 was the one with the gum. I predicted that it would get smaller (decrease). A little bit of chewing later the gum did decrease.
