Crater Design Experiment Aim: To see how the height in which the ball is dropped from affects the depth of the crater. Hypothesis: I predict that as the height in which the ball is dropped from increases‚ so does the depth of the crater (the data will be directly proportional). The scientific knowledge which supports this is that the golf ball has a gravitational potential energy which increases as the ball is dropped from higher heights. When the height increases the ball gains more gravitational

For the analysis of cell membrane permeability and the mechanism of controlling water‚ human red blood cell is a convenient specimen through hemolysis experiments ^^^^^. The human RBC osmotic content is about 0.9% NaCl. In hypotonic solutions‚ the cells swell because of water influx and eventually they hemolyze where cell contents including hemoglobin are released into the medium. This can be indicated by
