b Collect the pennies that landed heads-up and toss each penny once. Record the number of pennies that land heads-up i Data Table 1. c Repeat this process until all remaining coins land tails-up. Hote: Completely fill out the data table. Any remaining trials that were not conducted should be recorded as "0" in the data cable. For example, if it only takes 6 trials to reach all tails-up coin tosses, record a "0" for trials 7 - 10. 3 Repeat step 2 two more times, and record the results for Trial 2 and 3 in Data Table 1. 4 Graph the data in Data Table 1 of the half-lives for predicted number of parents and also actual parents in Trials 1, 2, and 3. Plot the number of parent isotopes on the dependent, vertical axis (y-axis) and plot the number of half-lives on the independent horizontal axis (x-axis). Add an exponential trendline to the predicted number of parents, Note: If you do not have access to graphing software, download and print the Graph Paper Template to create the graph and draw an estimated trendline. 5 Take a photo of the completed graph and upload the image into Graph 1.
