Microscopes need to make a booklet with 4 papers staples together
Title page Write “microscopes” Write your name, date and period number Draw a small picture of your chosing
Microscopic Images, page 2 (after the title page) What is it?

Microscope Safety Page 3
On page three of your book, complete the following tasks: Task: Page 3 On page three of your book, complete the following tasks: Write the underlined rule. Create and label a drawing for each of the microscope safety rules Briefly describe the rule for safety
No fingers on the Lens: Never touch the lens with your fingers Clean the lens with lens paper Fibers from paper towels or tissue may scratch the lens
Low Power and Raise Stage: To start, rotate the nose piece to the lowest objective Raise the stage so its as close as possible to the objective lens
Carry On Arm and Under Base: Use two hands to support the microscope One hand holds the arm and the other holds the base Never swing the microscope
Use Dust Cover: Place the microscope back where you got it Cover it with a dust cover
Clean: Clean all slides, materials and work area when done
Microscope Parts and Functions Use the following slides or Brainpop to understand the parts of the microscope and their functions. Page 4 – label the parts Page 5 – describe the functions Brainpop has an interactive video, Username – kyrenemiddle Password – bpop Go to “Virtual Labs: Using the Microscope” microscopes
1. Eyepiece Contains the lens you look through. Top part of the microscope.
2. Coarse Adjustment Knob Knob used to move the objective lenses toward or away from the specimen being viewed.
3. Fine Adjustment Knob Knob used to sharpen the image after first using the coarse adjustment knob.
4. Body Tube Connects the eyepiece and the objective lenses. Allows the light of the image to travel up from the objective lenses to the eyepiece.
5. Rotating Nosepiece Holds the objective lenses and rotates to change the magnification.
6. Objective lenses The lens that first receives the light rays from the object to be viewed. Attached to the nosepiece, vary in size. Shortest is the least powerful, longest most powerful.
7. Stage Supports the microscope slide being viewed. Large flat area directly under the objective lense, has a hole in the middle of it.
8. Stage Clips Hold the microscope slide in place on the stage.
9. Diaphragm Generally a five-holed disc under the stage. Used to control the amount of light passing through the aperture.
10. Mirror or Lamp Used to send light up through the aperture, the object, and the lenses. Located directly under the aperture between the legs of the base.
11. Arm Holds the upper portion of the microscope above the stage. Grasp the microscope from the arm anytime you decide to move it.
12. Base Supports the microscope and is used to carry it. Bottom part of the microscope.
Scientific Drawings Use the 6th page of your book to complete the following tasks: List the rules for creating scientific drawings Draw the sample diagram that explains the rules for drawing scientific images.
Scientific Drawings – page 6 All Drawings Must Contain the Following: Field of View(circle) Straight Lines Magnification Power Title Labels at the end of lines Use Pencil Detail, Detail, Detail!! Title Labels 100x
Create your own Scientific Drawing – page 7, if time. Pick 3 of the items at the front of the room. Draw a small portion(what you think you would see under the microscope) Your drawings must follow ALL 7 rules
