1) Why didn't each
group get the same results? |
|
|

2) Which follows the

average? Why? |

3) Did you have an
easier time predicting the results when there were a lot of pieces of candy
in the cup, or when there were very few? Why? |

1) Based on the
available radiometric ages, can you determine the possible age of the rock
unit that has acritarchs and bacteria? What is it? Why can't you say exactly
what the age of the rock is? 2) Can you determine
the possible age of the rock unit that has trilobites? What is it? Why can't
you say exactly what the age of the rock is? 3) What is the age of
the rock that contains the Triceratops fossils? Why can you be more precise
about the age of this rock than you could about the ages of the rock that has
the trilobites and the rock with acritarchs and bacteria? |
