Biomolecules, Lab Safety, Scientific Method Test Review

Which is NOT a step in the scientific method?

• Make observation
• Form a theory
• Collect data
• Form a hypothesis

What is a hypothesis?

• A hypothesis is the right answer to an experiment.
• A hypothesis is the wrong answer to an experiment.
• A hypothesis is an educated guess.
• I don't know.

Approved eye protection devices (such as goggles) are worn in the laboratory

•  to avoid eye strain
• to improve your vision
• only if you don’t have corrective glasses
•  any time chemicals, heat or glassware are used

Dependent variable means

• the scientist controls what to test
• educated guess
• ask a question
• what is being measured
