This lab activity on chemical reactionswill prepare your 8th grade middle school science and 9th grade physical science students to identify the physical properties that change during a chemical reaction. Students will also be able to identify and name the reactions and products involved in these reactions.
I recommend this free that is easy to use and display to your students.
