Microscope Parts Labeling Worksheet

A class is investigating the cells in a leaf. Use the microscope tasks below to identify parts, focus safely and plan a fair observation. Word bank: eyepiece, arm, revolving nosepiece, objective lens, stage clips, stage, diaphragm, light source, coarse focus knob, fine focus knob, base.

Meet the microscope

Use these numbered microscope-part clues to answer Questions 1–4. Number 1 is the part you look through. Number 4 is the lens closest to the specimen. Number 6 is the flat platform that holds the slide. Some parts in the word bank are not numbered.

1.Write the correct part name for numbers 1, 4 and 6.

2.Which part do you rotate to change from a low-power objective lens to a higher-power objective lens?

Arm
Revolving nosepiece
Diaphragm
Base

3.Match each microscope part to its main job.

Stage clips
Diaphragm
Fine focus knob
Base

Makes small adjustments to sharpen the image
Hold the slide in place
Controls how much light passes through the specimen
Supports the microscope

4.A leaf sample looks dark even though it is centred on the stage. Name one part you could adjust to improve the light reaching the sample, and explain how.

Focus safely and observe carefully

Think about how to focus safely during a microscope investigation. Make sure the slide is secure and use the microscope carefully.

5.Put these actions in a safe order by writing 1–4 beside each: ___ look through the eyepiece and sharpen with fine focus; ___ secure the slide; ___ select the lowest-power objective; ___ watch from the side while bringing the objective close to the slide.

6.True or false: Start focusing on high power and use the coarse focus knob to move the objective quickly towards the slide.

TrueFalse

7.The specimen is clear on low power but blurry after you switch to high power. Which knob should you try first, and why?

8.A student carries a microscope by gripping only the eyepiece. Describe a safer way to carry it and explain why.

9.Plan a fair observation comparing two leaf samples under a microscope. Name one factor to keep the same and one observation you could record.
