1.Approximately what fraction of chips was removed from the shoe box after each set of 5 shakes (half-life)?
2.How many times did you shake the box before only one chip remained?
3.If someone stopped you and counted only 12 chips remaining, could he or she have calculated the time (in # of shakes) you started the experiment? Explain!
4.Imagine that the shoe box is a fossilized bone that contains 24 pug (picomicrogram) of Carbon-14. When it was buried, it contained 100 pug of Carbon-14. If the half-life of Carbon-14 is 5730 years, how old is the bone? Show your work.
5.Based on what you learned in question 4, how many pug of Nitrogen-14 is in the bone? How much did the bone start with?
Was the hypothesis verified or nullified?
How could you change this experiment to ensure more accurate results?
