Aim: The aim of the experiment is to test the effect temperature has on the activity of the enzyme rennin. Hypothesis: I believe the rate of reaction will speed up as the temperature increases until it reaches about 37oC‚ which is the body temperature‚ where it will begin to slow down and stop reacting. I believe this will occur because enzymes have a temperature range at which they work best in and once the temperature goes out of this range the enzyme will stop working. Introduction:Enzymes are

NOTES FROM MR.ANDERSON’S WATER POTENTIAL VIDEO (SAVES TIME AND EFFORT!) Water potential is the potential energy of water per unit area compared to pure water. Which allows you to figure out where water’s going to flow due to osmosis‚ gravity‚ pressure and even surface tension. It also allows you to figure out if water will flow in the first place and if it will flow into the cell or not. Water Potential (symbol psi) = Solute Potential (symbol psi s) + Pressure Potential (symbol psi p) Solute

ent chemicals are added to each other. Procedure This experiment involved placing drops of specified chemicals into a well on a 96well plate. Each well number was recorded along with question number and name of chemicals involved. Two drops of a chemical were placed in a well along with two drops of another chemical. Chemical reactions and color changes were recorded in Data Table 1. Observations During the experiments a few problems were encountered. One of the chemicals provided differed
