We are going to apply our knowledge that we learned from yesterday. You will be given some problems (1 at a time). With your group, see if you can use scientific and standard notation to answer the questions.
Write the problems down and then figure out if your group can get a plan to solve them.
We will work the problems out on the board after each group tries to solve them first.
