Scientific Method and Safety Review
Purpose: Students will plan and implement comparative and descriptive investigations
by making observations, asking well-defined questions, and using appropriate equipment,
design and implement experimental investigations by making observations, asking welldefined questions, formulating testable hypotheses, and using appropriate equipment and
technology, and analyze data to formulate reasonable explanations, communicate valid
conclusions supported by the data, and predict trends.
Please use your textbook Chapter 1, the glossary, and/or technological device at your
teachers discretion to learn about the scientific method. Complete the questions below.

Part 4
1. Wear a lab apron when working with harmful chemicals. Wear safety
goggles when working with chemicals or heating substances. Wear
closed toe shoes (no sandals) when working in the lab.
2. Never conduct experiments without adult supervision and if you are
injured notify the teacher immediately.
3. Notify your teacher immediately if anything spills. Spills need to be
cleaned up quickly and correctly.
4. Never eat or drink in the lab.
5. Wash your hands thoroughly after handling chemicals, cultures, plants
or animals.
6. Pull long hair back and roll up long sleeves and remove ID when working
with flame.
7. Be sure that all laboratory surfaces, equipment and tools are cleaned
after you finish with them and dispose properly of all chemicals.
8. Turn off hot plates and burners when not in use.
9. To test the odor of fumes, waft the fumes toward your nose, do not
inhale. Explain why.
10. “Horseplay” in the lab is not tolerated under any circumstances. It
can lead to chemical spills, accidental fires, and broken equipment.
Never throw anything and no wrestling, punching or shoving in the lab
even if you’re just “playing”. Those types of behaviors will result in
your removal from the lab and you will earn a zero for that lab. You
may also be excluded from future labs due to inappropriate behavior.
