How far does 2100 minutes go?

Back in April I created an estimate of how long each unit would be.  The ranges on those estimates were wide ranging due to not knowing how much classroom time we would have.  As of now, time for science is set at 30 minutes a day for 70 days in grades K-2.  For grades 3-5, it goes to 60 minutes a day for 70 days. Science alternates its units with Social Studies.  The bottom line for now is that I have 2,100 minutes of curriculum time.

With this in mind, the tables below illustrate the order of the units, a brief statement about the PBA, the current estimate of unit lengths and what I estimated back in April.  Keep in mind that these are still estimates.  Three weeks from now, I will have a better idea.
