Scientific law- describes pattern in nature without explaining it
Scientific theory- explains pattern in nature
Scientific model- easy to see/ understand concept

Accuracy- closeness to actual measure
Precision- closeness of measurements to each other
Pg 20 3 temp. conversions!

4. 1.4 Presenting Scientific Data
Data Tables- organize quantitative and qualitative data collected
Graphs- line, bar, pie, scatter plots
Communicating Data- lab reports, publish, journals, speaking, attending conferences, peer review
