Designing different experiments regarding the same concept to investigate this topic further would be interesting. One experiment that could be done in the future could be using cold water instead of warm water. In this experiment the students studied how warm water affects the yeast, and learned that warm water activates the yeast enzymes. Where cold water may denature the enzyme, as the students previously reviewed that three factors that affect enzyme activity are temperature, concentration of enzyme, and pH level, and if any of these three factors were to exceed out of the specific range, the enzyme will denature. This would be compelling to test because the students will then see how the cold water affects the respiration rate. Another
