Successful completion of the course requirements:
Attendance is mandatory for each experiment listed in the schedule. Student will not be allowed to pass the course without completing all laboratory experiments. This includes a written pre-lab quiz (see schedule above), performance of the experiment in the laboratory, and a written report for each lab.
Lab experiments may require the full four hours to be completed.
If Student will be more than 20 minutes late to lab or miss lab without a valid written excuse, you will not be allowed to perform the experiment. If Student will miss a lab due to illness, must notify the Teacher within 24 hours of the lab period. A doctor?s note is indispensable to corroborate illness and it is a condition for making up the lab. If Student needs to miss a lab for a valid reason other than an illness, she/he must inform Teacher the week before the lab you will miss. Valid reasons do NOT include needing more time to do schoolwork or social obligations. A document must be brought to corroborate the absence.
Failure to complete all experiments, including prelab quizzes, will result in a failing grade for the course. Each quiz will is worth 3 points maximum and t complete the course student needs 6 points, minimum.
Experiments are graded based on the accuracy of the reported results.
