• Syllabus: Take 5 minutes to read over carefully.

• Prefix Suf Quiz tomorrow. All words have been sent Remind 101 to you.

Safety Contract

• Please read over the safety contract carefully.

• After this week you cannot perform a lab without turning in a signed safety contract.

Scientific Method

• Take notes on the movie. Think about how these two experiments were preformed. You will use the same steps in the worm lab.

How do you prepare a microscope slide?• 1) Carry the microscope to your station, with one

hand supporting the arm and the other the base• 2) Clean glass slide and cover slip as well as the

lenses with lens paper• 3) Place specimen in the middle of the slide• 4) Lower the cover slip and remove excess liquid• 5) Add stain if called for

Types of Microscopes
