Today in class, Mrs. Mandarino made sure that the whole class knew how to create and invite people to a Google Doc. There was no homework to check in today. Then for the rest of the class we worked on Sig Fig Rules and Scientific notation.
We finished up the Sig Fig Rule sheet in class today, reviewed scientific notation and learned that density is Mass over Volume. When dividing the numbers, remember to use proper sig figs.
We only started the Scientific worksheet and the rest of it was for homework, but we learned that if you have to go left to find the decimal point then your exponent wil be negative (I.E. 7.300 x 10^-5= .00007300) and if you move the decimal point to the right then your exponent will be positive.
The homework for today was to finish your Google Doc and either send it to Mrs. Mandarino or bring in a hard copy, work on webassigns and ws p. 5 & 6 #2.
