The subject provides the thread that links the responses together. Respond to postings of the igniter and other classmates. Use Reply when you respond, rather than starting a new message. This keeps the messages on the subject threaded together. The laboratory is an integral part of this physics course.
All scientists keep some form of organized record of their experimental work.
In keeping with this tradition, you should record your experimental work in a laboratory notebook. Details on using the notebook are found in the Physics Laboratory Notebook discussion in the lab manual. Read this discussion before beginning your first lab. You will find it useful to review this discussion several times during the term. The summary should be just that, a brief overview of the experiment and your experimental results as described in the Lab Manual.
