Balancing Equations Challenge

The Balancing Equations Challenge software includes 1) tutorials on the history and meaning of the conservation of mass, 2) a number of strategies on how to balance chemical equations, 3) directions on solving problems using the software, and 4) four sets of practice problems of increasing difficulty. Two of the sets of practice problems include help by showing the number of reactant and product atoms to guide the user along. Scores are kept for all four sets and the total score can be saved to a high score table. The software is composed of 75 screens.
