Parts of Microscopes 6 th Grade Science Intro to Microscopes Barbara Bloemers
Michigan Benchmarks Or Why Do I Have to Know This?
Microscope One of the most important tools used to study living things. “Micro” means very small “Scope” means to look at Diagram of a typical student light microscope, showing the parts and the light path
Test Your Knowledge #1 The word “microscope” means: A. Glass eye B. Small ~ to look at C. To search for
You are Correct! The word “microscope” means VERY SMALL ~ TO LOOK AT
Oops! Micro means “very small” Scope means “to look at” What do you think microphone might mean?
Basic Microscope Parts 1.Base 2. Light source 3. Diaphragm 4. Stage 5. Stage clips 6. Low power 7. High power 8. Nosepiece 9. Arm 10. Fine Focus 11. Body Tube 12. Course Focus 13. Eyepiece
Guess What? We will now look at the 13 major parts of the microscope and what their functions are that enable us to see very small things.
Introducing the Arm and Base Arm Supports the body tube. Used to carry the microscope. Base Bottom part of the microscope often shaped like a horseshoe.
Diaphragm and Light Source Diaphragm Changes the amount of light reaching the objective lenses. Located under the Stage. Light Source Located beneath the Stage and Diaphragm. Sends light towards the hole in the stage.
Great Job! Well Done Now that we have learned the parts let’s see how we can use the microscope.
Follow these instructions when using the microscope. Click on each underlined word. 1. To carry the microscope, grasp the ARM with one hand. Hold the BASE with your other hand. Using the Microscope in 10 Steps
10 Steps to Using the Microscope 2. Adjust the DIAPHRAGM while looking through the EYEPIECE. 3. Adjust the LIGHT SOURCE (mirror) until you see the circle of light.
10 Steps to Using the Microscope 4. Place the slide on the STAGE. 5. Center the SPECIMEN over the small opening on the STAGE. 6. Secure the slide with the STAGE CLIPS.
10 Steps to Using the Microscope 7. While looking at the STAGE from the side, turn the COURSE FOCUS KNOB to lower the BODY TUBE until the LOW POWER OBJECTIVE almost touches the slide.
10 Steps to Using the Microscope 8. While looking through the EYEPIECE, carefully move the COURSE FOCUS KNOB until the specimen comes into view. 9. To switch to the HIGH POWER OBJECTIVE LENS, look at the microscope from the side.
10 Steps to Using the Microscope 10. Move the NOSEPIECE until the HIGH POWER OBJECTIVE LENS “clicks” into place. If the lens hits the slide, the slide and/or lens might break. Turn the FINE FOCUS KNOB until the specimen comes into focus.
