These are the summary questions you will need to answer at the end of the semester about the observations you have made and logged throughout the semester. For detailed instructions on how to make your observations, see this page.
Please note the statements on that page regarding fabricated observations. For this part of the project, do not summarize or discuss observations you did not make. If you fabricate observations on this summary, the 20 point deduction from your project grade will apply.
You may find Chapters 2 and 3 of the textbook useful in answering these questions. You may also consult a Moon phase calendar to assist you in this part of the assignment.
