Purpose: The purpose of this lab is to test the effects of osmosis on eggs in hypertonic solutions and hypotonic solutions. Hypothesis: If the corn syrup is a hypertonic solution‚ then the egg’s size will shrink. If the water is a hypotonic solution‚ then the egg will swell. Materials: Styrofoam cups (2 per group) Styrofoam cups to weigh down egg (2) Balance Paper towels Vinegar (enough to cover egg) Distilled water Corn syrup Fresh eggs (2 per group) Procedure: Day

Experiment: At this experiment we are investigating does the temperature affect how quickly the particles diffuse to an even concentration throughout the water‚ we are going to do this experiment by using food coloring to see how quick the food coloring diffuse in hot water and cold water. Materials: • • • • • • • • One beaker Hot plate Ice Water Food coloring Thermometer Timer Eye dropper Hypothesis:I think the food coloring will spread faster‚ because the particle in the hot water have more

enzyme’s activity are temperature and pH‚ and each enzyme works best at a particular temperature and pH. The purpose of this enzyme kinetic experiment was to observe the effect of temperature and pH on the reaction of barley alpha-amylase enzyme with starch substrate and establish the optimum temperature and pH for this reaction. The optimum temperature and pH for the reaction of alpha-amylase and starch was predicted to be a temperature of 50°C and a pH of 5. The optimum temperature and pH for the reaction

The effect of increasing substrate concentration on rate of an enzyme reaction. Enzymes are biological catalysts that lower a reactions activation energy making possible many of the reactions needed for life to exist. Enzymes have a high specificity which have been explained by many theories such as Fischer’s lock and key. Currently the most widely accepted theory is the induced fit hypothesis proposed by Koshland in 1958. This hypothesis solves some of the problems with the Lock and key theory
