This week we will use evidence of chemical changes to identify unknown substances. We will review the differences between chemical and physical changes on Monday with a BrainPop video and Kahoot game. Tuesday's investigation will have a Halloween theme. Block Day's Mystery Powders investigation will include more than a dozen different chemical reactions. On Friday, students will take an Evidence of Chemical Change Quiz.
