Do Not Write on This Exam!
Test Number: _____
Unit 1 Exam: The Nature of Science
The Metric System, Lab Equipment, and Lab Safety Rules/Stations
Instructions:
1. Do not write on this test. If you accidentally do so, let me know immediately so that I can give
you another exam. If you see a mark from the previous period, let me know immediately.
2. Put your name, date, and period at the top right of your scratch piece of paper. You must turn
this in at the end of the test, even if you end up not using it.
3. Copy the board and put the proper heading on your scantron sheet, including the correct Test
Number. Failure to do this exactly will result in a loss of 10 points from your total score.
4. For each of the following questions, clearly mark the correct letter/answer for each question on
the scantron. If you do not mark it clearly, or carefully erase any of your changes, then the scantron
machine will mark your answer wrong. You will not be given any credit for such errors.
5. Do not let your eyes ‘wander’ nor communicate in any way with other students (even after
you have turned in the test), or you will receive a zero, no exceptions! When you are done, put
your test on the stack of other tests in front of the classroom, and silently read your science book at
your desk. If you have a question, please raise your hand, and I will help you. Good luck!

That’s it! Double check your answers as well as for any stray pencil marks on your scantron. Also,
make sure that you filled in the scantron information correctly, INCLUDING YOUR TEST
NUMBER. Remember, there is still NO talking or communicating with any student, as others are
still taking the test. If you do look at or communicate verbally or non-verbally with anyone (besides
an adult), then you WILL receive a ZERO. NO EXCEPTIONS.
Silently turn in the exam, scantron, and scratch paper (even if it wasn’t used) at the proper 3 places
at the front of the classroom. Silently grab a green Holt Life Science Book and read Chapter 4 on
Cells. You may take notes on this and summarize it for bonus points, if you desire.
