This week we're getting into how to describe materials/substances. Have a discussion about what are pure substances and what materials are not. I'm going to back away from this discussion and watch you guys monitor each other. Be respectful as I will be watching, but discuss how you know something is a pure substance and what is not. Be sure to evaluate what others think.
This blog is for you...
Feel free to share some curious train of thought you have, as well as share your thoughts on others.
