Unit: Laboratory & Measurement
Topics covered in this chapter:
1. The Scientific Method
2. Designing & Performing Experiments
3. Accuracy & Precision
4. Uncertainty & Error Analysis
5. Keeping a Laboratory Notebook
6. Formal Laboratory Reports
The purpose of this chapter is to teach skills necessary for designing and
carrying out laboratory experiments, recording data, and writing summaries
of the experiment in different formats.
- Designing & Performing Experiments discusses strategies for coming up
with your own experiments and carrying them out.
- Accuracy & Precision, Uncertainty & Error Analysis, and Recording and
Analyzing Data discuss techniques for working with the measurements
taken during laboratory experiments.
- Keeping a Laboratory Notebook and Formal Laboratory Reports discuss
ways in which you might communicate (write up) your laboratory
experiments.
Calculating uncertainty (instead of relying on significant figures) is a new and
challenging skill that will be used in lab write-ups throughout the year.
