Our Changing Earth

Parents: Third and fourth grade scientists have been learning about our "Changing Earth".  This week, we took much of what we have learned to study the erosion of Niagara Falls.

Third and Fourth Grade Scientists:  This week our question was:  Will Niagara Falls be around in 20 years?  Will they be around in 100 years?  If so, how long will it take for the falls to erode back to Lake Erie?  Please answer this question and explain the process you went through to find out. (Answer the question as a comment by clicking on the "comments" link below.)

Below is a link to some interesting information about Niagara Falls and a video that you can watch at home that has some spectacular views of the falls.

It was kind of hard.I had to add all the #'s together and see if I wanted the sum or the median. So it was pretty hard in the long run.
