Parts of the Microscope Worksheet with Answers | Biology Worksheet - Free Printable

Let's solve this step-by-step by identifying and labeling each part of the microscope using the provided word bank:

Word Bank:

- arm
- base
- coarse focus
- eyepiece
- stage clip
- illumination mirror
- objective lens
- nosepiece
- fine focus
- eyepiece tube
- body tube
- specimen stage

Step 1: Identify the parts from top to bottom

1. Topmost black cylinder → This is where you look through to see the specimen.
✔ Eyepiece

2. Tube connecting the eyepiece to the objective lenses → This holds the eyepiece and connects to the nosepiece.
✔ Eyepiece tube

3. The round metal structure near the eyepiece that adjusts the focus (larger knob) → This is used for large adjustments in focus.
✔ Coarse focus

4. Smaller knob below the coarse focus → Used for fine adjustments.
✔ Fine focus

5. The curved arm-like structure connecting the upper part to the base → This is what you hold when carrying the microscope.
✔ Arm

6. The rotating part with multiple lenses → Holds the objective lenses.
✔ Nosepiece

7. The individual lenses on the nosepiece → These magnify the specimen.
✔ Objective lens

8. The flat platform where the slide is placed → Holds the specimen.
✔ Specimen stage

9. The clips on the stage that hold the slide in place →
✔ Stage clip

10. The mirror at the bottom beneath the stage → Reflects light up through the specimen.
✔ Illumination mirror

11. The bottom wide support of the microscope → Provides stability.
✔ Base

Final Labels (from top to bottom):

| Line Number | Part Label |
|-------------|------------|
| 1 | Eyepiece |
| 2 | Eyepiece tube |
| 3 | Coarse focus |
| 4 | Fine focus |
| 5 | Arm |
| 6 | Nosepiece |
| 7 | Objective lens |
| 8 | Specimen stage |
| 9 | Stage clip |
| 10 | Illumination mirror |
| 11 | Base |

How to Fill It In:

On the worksheet, write the correct label next to each red line:

- Top line → Eyepiece
- Second line → Eyepiece tube
- Third line → Coarse focus
- Fourth line → Fine focus
- Fifth line → Arm
- Sixth line → Nosepiece
- Seventh line → Objective lens
- Eighth line → Specimen stage
- Ninth line → Stage clip
- Tenth line → Illumination mirror
- Bottom line → Base
