1. Practice and review and ASK QUESTIONS
Microscope Review
This presentation reviews content we have already completed in class, in a variety of assignments.
This is NOT new.
Practice and review and ASK QUESTIONS

2. Introduction to the Microscope
Safety and Care
Parts
Focusing
Students will have their microscopes out, for reference as we go through each of the steps. As an introduction, students will be asked what kinds of things they can do with this tool.

3. Safety and Care Store in a cool, dry place Have cord folded and banded
Cover with dust cover
Stage all the way down
Low power objective at stage
Eyepiece over arm
Do not stack

4. Microscope Care Always carry with 2 hands
Only use lens paper for cleaning
Do not force knobs
Always store covered
Keep objects clear of desk and cords
Teacher demonstrates how to hold the microscope, where the lens paper is located and how to use it. Students will be invited to turn the knobs and observe the stage as it moves up and down. Teacher will demonstrate how to store the microscope.

5. Microscope Parts Eyepiece Body Tube Revolving Nosepiece Arm
Objective Lens
Stage
Stage Clips
Coarse Focus
This is the exact version of the microscope used in class. Students will be identifying the parts on the microscopes at their desks as we go along and what their functions are.
Diaphragm
Fine Focus
Light
Base

7. Using the Microscope Place the Slide on the Microscope Stage
Use Stage Clips
Click Nosepiece to the lowest (shortest) Objective
Move stage closest to objective
Look into the Eyepiece
Use the Coarse Focus
THEN, Use the fine focus
Use the pointer to keep track of your specimen
Give students a slide from the “common things” set, each student will practice focusing and changing objectives.

8. Using High Power Follow steps to focus using low power
Click the nosepiece to the longest objective
Do NOT use the Coarse Focusing Knob
Use the Fine Focus Knob to bring the slide
Have students exchange slides so they can look at different things, walk them through using the high power objective to focus slides. Emphasize not using the coarse objective during this process, as it will crack the slides.
What can you find on your slide?

9. Microscope Investigation
You have observed plant, animal, protists.
You have sketched and photographed.
Can you see any organelles? If so, which ones?
Why or why not?

10. Questions
1. State 2 procedures which should be used to properly handle a light microscope. 2.      Explain why the light microscope is also called the compound microscope. 3.      List the procedures for preparing a wet mount slide.

11. Remember from cell organelle study
Eukaryotes vs. Prokaryotes
And
Examples of each
Know how classify plant, animal, fungus, protest, and bacterial cells in one of those categories.

12. Plant cells vs. animal cells
Be able to identify the differences

13. Protists, protozoa
Protozoa are single-celled eukaryotes (organisms whose cells have nuclei) that commonly show characteristics usually associated with animals, most notably mobility and heterotrophy. They are often grouped in the kingdom Protista (protists) together with the plant-like algae and fungus-like water molds and slime molds.

14. Bacterial cells, 1 ALSO SEE Cellsalive.com
A prokaryotic cell has five essential structural components: a nucleoid (region) (DNA),ribosomes, 
cell membrane, 
cell wall, and some sort of surface layer, which may or may not be part of the wall.

15. Bacterial cells, 2; SEE Cellsalive.com
There are three regions: appendages 
(attachments to the cell surface) in the form of flagella and pili (or fimbriae); a cell envelope consisting of a capsule, cell wall and plasma membrane; and a cytoplasmic region that contains the cell chromosome (DNA) and ribosomes  (Figure 1).
