Learning Intentions

​Mistake on the Handout

Cross off the last circle on your assignment. You will only need to observe your letter under 40x, 100x, and 400x. You will still answer the questions on the last page. The directions also say "courage" instead of "encourage".

Reminders

• If you need to move the microscope, carry it with the arm and base.

• The slides are glass. They are breakable! Be careful.

• If something breaks, tell me. Do not clean it up yourself!

• If your lens is smudged, get lens paper from Ms. Archer.

• Please be respectful of the equipment. You can lose lab privileges if you are not acting properly.

• Ask Ms. Archer if you have any questions or need help.

Groups

• Get into groups of 3

• Once you are in your groups, I will assign you to a microscope

• Send one member of your group to grab your letter, slide, and coverslip from me.

• At the end of class, return all materials to me. Put your stage all the way down, put your objective lens to the lowest setting, and turn off your microscope.
