Lab Notebooks
Why keep a lab notebook?
1. One needs to document the work that is completed in the lab. You may use the data and/or the analysis to
apply the concepts to solve additional problems you may find later.
2. You should be able to think about your lab experience and to observe how a single factor can impact a system or
situation.
3. You should have complete procedures and data so the entire experiment may be duplicated by someone else to
verify your results.
What should your lab notebook look like?
1. The first few pages should be a table of contents to which you may add your lab titles and page number as you
complete the labs. Number your pages in the upper margins consecutively.
2. Always sign and date each lab at the bottom of the page.
3. If you make a mistake, do not erase or tear out the page, simply draw a line through the error. On more than
one occasion, an error is actually the correct conclusion or answer.
4. One should use pen in the lab notebook. Pencil will smear and is easily erased.

5. If you should need to stop a lab and finish it the next day, draw a line and initial below the line. You may resume
your lab or analysis on the next day.
Notebooks:
You will be required to view short clips or read short passages and take notes concerning the item assigned. Notes
pages will look like the page below. Use the directions in each section to know what to write in that area.

Science Safety Rules
The Bikini Bottom gang has been learning safety rules during science class. Read the paragraphs below to find
the broken safety rules and underline each one. How many can you find?
SpongeBob, Patrick, and Gary were thrilled when Mr. Krabbs gave their teacher a chemistry set! Mr. Krabbs
warned them to be careful and reminded them to follow the safety rules they had learned in science class. The
teacher passed out the materials and provided each person with an experiment book.
SpongeBob and Gary flipped through the book and decided to test the properties of a mystery substance.
Since the teacher did not tell them to wear the safety goggles, they left them on the table. SpongeBob lit the
Bunsen burner and then reached across the flame to get a test tube from Gary. In the process, he knocked
over a bottle of the mystery substance and a little bit splashed on Gary. SpongeBob poured some of the
substance into a test tube and began to heat it. When it started to bubble he looked into the test tube to see
what was happening and pointed it towards Gary so he could see. Gary thought it smelled weird so he took a
deep whiff of it. He didn't think it smelled poisonous and tasted a little bit of the substance. They were
worried about running out of time, so they left the test tube and materials on the table and moved to a
different station to try another experiment.
Patrick didn't want to waste any time reading the directions, so he put on some safety goggles and picked a
couple different substances. He tested them with vinegar (a weak acid) to see what would happen even
though he didn't have permission to experiment on his own. He noticed that one of the substances did not do
anything, but the other one fizzed. He also mixed two substances together to see what would happen, but
didn't notice anything. He saw SpongeBob and Gary heating something in a test tube and decided to do that
test. He ran over to that station and knocked over a couple bottles that SpongeBob had left open. After
cleaning up the spills, he read the directions and found the materials he needed. The only test tube he could
find had a small crack in it, but he decided to use it anyway. He lit the Bunsen burner and used tongs to hold
the test tube over the flame. He forgot to move his notebook away from the flame and almost caught it on
fire.
Before they could do another experiment, the bell rang and they rushed to put everything away. Since they
didn't have much time, Patrick didn't clean out his test tube before putting it in the cabinet. SpongeBob
noticed that he had a small cut on his finger, but decided he didn't have time to tell the teacher about it. Since
they were late, they skipped washing their hands and hurried to the next class.

Your assignment is to WRITE a two paragraph essay listing the safety violations in the preceding story about
Sponge Bob. Each paragraph should contain a minimum of 5 sentences. This assignment is due Friday,
September 5, 2014. You may write the essay below or type the essay and print it out.
REMEMBER: If you write and I cannot read it, it is a zero.
This assignment is worth 15 points. I will be looking for the lab safety violations, your reasons why they are
violations and clarity in your writing.
