Inserts- You will often have information to insert into your logbook (e.g., computer printouts). These should be taped into the book to continue the flow of your experimental work. Be sure to identify and label all such material so that it is clear what information has been included. Questions: Answer all numbered questions completely and clearly. You do not need to rewrite the questions, but be sure you include enough information in your answer so someone reading it (like your instructor) will know to what you are responding. One-word answers are never a good idea. Wrap-Up Discussion at End of Each Lab: Accuracy: Your report should include a brief discussion of how your results or techniques could have been improved. Do NOT simply say "Experimental error" and do not make excuses for sloppy work. Answer the question, "If I were to repeat this experiment, what could I do differently to improve my results?" Implications: At the end of your report, write a concluding statement about the "big idea" of your work. Do not just restate a final number, but summarize the general physics concepts that were used and the implications of these concepts. This is often the most important part of your lab report so be sure to put time
11 and thought into writing a useful statement. Try to answer the question, "What did all of this mean?" Participation: Each lab student is expected to participate in all aspects of the lesson, to contribute to the group’s work, and to allow and encourage the active participation of the other group members. Effective group work is one of the skills most sought after by employers and health practitioners and this laboratory course should provide you with experience in working as a group member. You can expect to change your partners during the term.
