Graphing

What you need  Title of Graph  Axis Labels Variables Units Scale  Legend (if more than one data set)

Things to remember  Make it big Use most of the sheet of paper Make scale fit appropriately You are not required to start at zero!  Write legibly  Use graph paper

Vocab  x- axis Horizontal axis Independent Variable (What you control) Time is usually an independent variable  Y-axis Vertical Axis Dependent Variable (What changes because of x)

Interpreting your graph  Interpolate Using a line to make an estimate between data points  Extrapolate Using a line to make an estimate that goes beyond your data points  Line of best fit THIS DOES NOT MEAN CONNECT THE DOTS! Only rarely will a graph need to have the data points connected by a jagged line. Usually, it is best to guess at a (straight) line that goes as near as possible to as many points as possible.

Can we interpolate or extrapolate this graph?  What was the temperature of the hot water at 25 min?  What was the air temperature at 13 min?

Can we interpolate or extrapolate this graph?  What will the temperature of the hot water be at 50 min?  What will the air temperature at 45 min?  What will the temperature of the cold water be at 50 min?
