1 Introduction to the Microscope
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.

2 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.

3 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

4 Warm-Up Put on page 4 below previous warm up.
How should you carry a microscope? What do you expect to be able to see in the turtle water slides? Will the bacteria stay still?

5 Using the Microscope Place the Slide on the Microscope Use Stage Clips
Click Nosepiece to the lowest (shortest) setting Look into the Eyepiece Use the Coarse Focus Give students a slide from the “common things” set, each student will practice focusing and changing objectives.

6 Using High Power AFTER the object is in focus using the low power objective. Click the nosepiece to the longest objective Do NOT use the Coarse Focusing Knob Use ONLY the Fine Focus Knob to bring the slide into focus 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.

7 Magnification A how to guide...

8 MULTIPLY

9 Magnification Elodea 40 x Elodea 100x Elodea 400x

10 When Your Done Turn off the lamp Lower the stage completely
Click in the lowest power objective Wind cord and secure with twist-tie or similar. Replace cover
