Very interesting application for chemistry and physics teachers is PHET. We choosed for you one part: https://phet.colorado.edu/en/simulation/balancing-chemical-equations
- Chemical Equations
- Conservation of Mass
How do you know if a chemical equation is balanced? What can you change to balance an equation? Play a game to test your ideas!
Sample Learning Goals
