Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

How do you teach a student with visual impairments about the conservation of mass? You use tactile models that represent the theoretical concept. Baking soda and vinegar are used to add gas to a deflated balloon. Learners will feel the...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

Here's a fun game on a very serious matter. Scholars play a board game to learn about personal energy use and consumption. They see how various choices affect their energy use and costs, and then apply this knowledge to brainstorm ways...

This lab experiment shows students that mass is not gained or lost during a chemical reaction. Lab also includes a set of lab questions that requires students to balance the chemical equation for the reaction that occurs in this lab.
