Equipment, size of equipment, and amounts of substances need to be included to get your full credit. If a History teacher walked in and wanted to perform YOUR lab, they could by using your procedures 7

Observations In paragraph form using proper grammar, describe in detail the observations that you made when performing this lab. Observations cannot be too long or too detailed. If you think you’ve written enough, you’re probably only half way there! 5 sentences minimum

Conclusion Write the 5 conclusion questions in this section. Answer the questions ALSO…answer the following: 1. Was your hypothesis supported or refuted (pre-AP) 2. List TWO errors that occurred during the lab. Examples of an UNACCEPTABLE error is: I broke the glass and had to start over. I ran out of time. The equipment wasn’t working. My lab partners are idiots.  WHAT ARE SOME POSSIBLE ERRORS IN THIS LAB?

Presentation This report should be typed, single spaced, 12 pt font. A hard copy will be due in class next Friday, SEPTEMBER 11th. YOU CANNOT EMAIL ME THE REPORT. I NEED A HARD COPY. You need to write your OWN report. IF its evident that you worked together on portions of the lab that needed to be done by yourself, you will receive a zero and have to see Ms. Carter. I have plenty examples of good lab reports. See me if you need help.
