weighted percentages ; scientific notation (using sig figs) ; percent error calculations ; Significant figures; Precision, accuracy, measuring with sig figs; Dimensional analysis (conversions!) Creating a linear equation from a graph; Buoyancy: why/how something floats
Also helpful to keep in mind in case you are not good with your calculator: mulitplication/division with scientific notation
