Microscopes are an essential tool to use when studying cells. They allow us to see things that we wouldn’t be able to see with the naked eye. In order to study cells in detail, it's important that students learn how to use a microscope. Before using microscopes in the classroom, they should understand the names and function of each part. In this activity, students will create a poster of a microscope with labeled parts. Students will identify and describe the microscope parts and functions. This is an awesome activity to complete at the beginning of either the school year or the unit on basic cells.
| Part | Description |
|---|---|
| Eyepiece Lens | The part of the microscope where you look through |
| Arm | Supports the eyepiece lens and connects it to the base (also a handle for carrying) |
| Objective Lenses | Three or four lenses with a range of different magnifications |
| Stage | A platform which holds the slide for observation |
| Slide | A thin piece of glass that holds the specimen |
| Focus Wheel | Used to bring the object in and out of focus |
| Lamp | Provides light to illuminate the specimen, sometimes a mirror is also used |
| Base | Supports the microscope |
In addition to optical microscopes, you can also run an activity looking at electron microscopes, which allow scientists to see things that are much smaller and in much greater resolution than optical microscopes. As an extension of this parts of a microscope labeling activity, have your students create a narrative storyboard on how to correctly prepare and observe cells using a microscope.

Student Instructions
In order to carry out an investigation to show that living things are made of cells you need to be able to use a microscope. Knowing the names of the different parts of the microscope is essential to be able to use one properly. Create a poster that labels the parts of a microscope and includes descriptions of what each part does.
Start with a basic introduction to microscopes, highlighting their significance in microbiology. Explain how microscopes allow scientists to observe organisms and structures that are too small to be seen with the naked eye. Use visuals and simple explanations to illustrate the types of microorganisms (like bacteria, viruses, and fungi) that can be studied with a microscope.
Conduct a hands-on activity where students label the parts of a microscope. Provide them with diagrams or actual microscopes, and guide them through the function of each part, such as the lens, eyepiece, and stage. This foundational knowledge is crucial for understanding how microscopes are used in microbiological studies.
Once students are familiar with the parts of the microscope, demonstrate its usage using prepared slides. These slides can contain simple microorganisms, such as pond water samples or cheek cells. Show students how to adjust the microscope to view these samples and discuss what they observe. This step bridges the gap between theoretical knowledge and practical application.
Transition from the practical microscope activity to an introductory lesson on microbiology. Discuss the types of organisms typically studied in microbiology, their roles in the environment, and their importance to human health. Encourage students to ask questions and express their curiosity about microscopic life forms.
The different parts of the microscope include: eyepiece lens, arm, objective lenses, stage, slide, focus wheel, lamp, and the base.
The function of a microscope is to examine and analyze small objects and organisms up close and in great detail. Using a microscope diagram labeled, students will better understand how each part of the microscope works.
