Liters – used to measure volume (amount of space taken up)
Density – ratio of an objects mass to volumeD = M/V
5 Ways to Presenting Scientific Data: data table – useful for organizing data
graphs – useful for showing changes in data
1. Line
2. Bar
3. Circle
4. Pictograph
2 types of graphs
1. direct proportional
2. inverse proportional
