This is a good activity for students who are just beginning to balance chemical equations. The paper gives a brief explanation and then directs students to go to an Internet site to complete the simulation. I posted this on Google classroom and had them jot down the score for each level and a sample equation on a separate piece of paper. If you were going to hand this out as a paper, you could add spaces for them to answer questions. The simulation shows them the chemical equation and a visual of each type of atom/compound on both sides of the equation.
