Materials graph paper ruler penny Procedure 1. Flip a penny 100 times, and in the Data Table record the total number of heads that result. 2. Now flip the penny the same number of times as the number of heads that you obtained in the first 100 flips. Record the number of flips and the number of heads in the Data Table. 3. Continue until you obtain no more heads. Note: You may not get to Trial #7 or you may go beyond Trial #7. 4. Using graph paper, plot the number of flips (y axis) versus the trial number (x axis). Draw a smooth line through the data points. Questions 1. Examine the graph. Is the rate of the number of heads produced over time linear or nonlinear? 2. Is the rate constant over time or does it change? 3. Why does each trial reduce the number of heads by approximately 1/2? Page 1
