3. Todays lab groups You will meet with your color-coded team
Each of the next three labs will be with a new group
Today’s lab is Balanced and Unbalanced Forces
Everyone must write up the lab, so make sure that everyone gets the data needed to do their calculations
We Will Read Balanced and Unbalanced force background on pg. 4 of the lab before starting
Follow instructions carefully, you will need to put together your inclined plane.
