Hello, I am working on an educational game and we are trying to visualize energy spent to carry out a nuclear reaction and energy received. One idea is to put this roughly on a graph. Keep in mind that energy spent could be considered "negative" and energy received "positive". All that we want to show is that it takes energy to carry out a nuclear reaction (energy spent) and that after the reaction some energy is received and that received energy is greater than energy spent. Keep in mind that the bars will be animated in from 0 value to whatever the correct value is, starting with the energy spent first and then the energy received. Which of these 3 graphs do you think would feel more intuitive to 8th and 9th graders? Graph A Graph B Graph C Thank you!
