Who doesn’t love glow sticks?! This lab will engage your students with the Law of Conservation of Mass like you have never seen. Students will determine the mass of the glow stick before cracking it and see how it compares with the mass after the reaction is complete (inside secret...they are the same). This lab can be used to engage, explain, or elaborate on how the before and after masses stay the same in a chemical reaction.
