Step-by-step solution for: Parts of a Microscope worksheet
Let's solve this step-by-step by identifying and labeling the parts of the compound microscope based on the image and the provided key.
---
The image shows a compound light microscope, which has several labeled blank boxes pointing to different parts. We need to match each part with the correct name from the "Microscope Key Parts" list.
---
We'll go through the numbered key and match them to their corresponding locations in the diagram.
#### From the Key List:
1. Eye Piece (Ocular Lens)
→ Located at the top of the microscope, where you look through.
✔ Topmost black tube — this is the eyepiece.
2. Coarse Adjustment Knob
→ Larger knob used for initial focusing. Usually located on the side of the arm.
✔ Large knob on the left side of the arm — this is the coarse adjustment knob.
3. Fine Adjustment Knob
→ Smaller knob below the coarse one, used for precise focusing.
✔ Smaller knob below the coarse knob — this is the fine adjustment knob.
4. Arm
→ The curved part connecting the base to the body tube.
✔ Curved structure connecting the base to the upper part — this is the arm.
5. Stage
→ The flat platform where the slide is placed.
✔ Flat platform with clips — this is the stage.
6. Stage Clip
→ Clips that hold the slide in place on the stage.
✔ Two small metal clips on the stage — these are the stage clips.
7. Base
→ The bottom support of the microscope.
✔ Bottom wide part — this is the base.
8. Body Tube
→ The tube connecting the eyepiece to the nosepiece.
✔ Vertical tube between eyepiece and objective lenses — this is the body tube.
9. Revolving Nosepiece
→ Rotating part holding the objective lenses.
✔ Circular piece below the body tube with multiple lenses — this is the revolving nosepiece.
10. High Power Objective Lens
→ One of the lenses on the nosepiece, usually larger or marked as 40x.
✔ One of the lenses on the nosepiece (likely the one closest to the stage) — this is the high power objective lens.
11. Low Power (Scanning) Objective
→ The smallest objective lens, often 4x.
✔ The shortest lens on the nosepiece — this is the low power (scanning) objective.
12. Diaphragm
→ Located under the stage, controls light passing through the specimen.
✔ Round disc beneath the stage with adjustable opening — this is the diaphragm.
13. Light Source
→ Located at the bottom, provides illumination.
✔ Circular area beneath the stage — this is the light source.

Now, let’s assign each label to the correct box:
1. Top box (eyepiece) → Eye Piece (Ocular Lens)
2. Box pointing to large knob on the left → Coarse Adjustment Knob
3. Box pointing to smaller knob below it → Fine Adjustment Knob
4. Box pointing to curved side → Arm
5. Box pointing to flat platform → Stage
6. Box pointing to clips on stage → Stage Clip
7. Box pointing to bottom base → Base
8. Box pointing to vertical tube → Body Tube
9. Box pointing to rotating lens holder → Revolving Nosepiece
10. Box pointing to higher lens → High Power Objective Lens
11. Box pointing to lower lens → Low Power (Scanning) Objective
12. Box pointing to round disc under stage → Diaphragm
13. Box pointing to bottom light → Light Source

- Top (eyepiece): Eye Piece (Ocular Lens)
- Left side, large knob: Coarse Adjustment Knob
- Below coarse knob: Fine Adjustment Knob
- Curved side: Arm
- Flat platform: Stage
- Clips on stage: Stage Clip
- Bottom wide part: Base
- Vertical tube: Body Tube
- Rotating lens holder: Revolving Nosepiece
- Higher objective lens: High Power Objective Lens
- Lower objective lens: Low Power (Scanning) Objective
- Round disc under stage: Diaphragm
- Bottom light: Light Source

This worksheet helps students learn the anatomy of a compound microscope. By matching the labels correctly, they understand how each part contributes to viewing specimens.
> Tip: Remember the order: Eyepiece → Body Tube → Nosepiece → Objectives → Stage → Diaphragm → Light Source.
