Find out where materials are stored and where to dispose of chemicals or specimens. Bring your lab notebook and worksheets to record and summarize your findings. If you're collecting data during an experiment, keep in mind that there's no such thing as a perfect measurement. Two people following the same instructions may come up with different results. When you chart or graph you results, your data points may not follow a straight line or smooth curve.
Mathematical formulas are precise, while our measurements are approximations.
This is more important than the result of any one experiment.
