Microscope Study Worksheet Cheat Sheet (DRAFT) by

To understand the structure, function, and application of compound and dissecting microscopes.

This is a draft cheat sheet. It is a work in progress and is not finished yet.

Pre-Lab Questions:

1. What is a Micros­cope? (Define what a microscope is and its purpose.)




2. Types of Micros­copes: (Research and list different types of micros­copes and their primary uses. What are the main differ­ences between a compound microscope and a dissecting micros­cope?)






3.Parts of the Micros­cope: (Label the parts of a compound microscope and a dissecting microscope from a diagram. Describe the function of each part (see below for detailed descri­pti­ons).






4. Microscope Safety: (List at least three safety rules to follow when using a micros­cope.)





5. Hypoth­esis: (Predict what you might observe when viewing a sample of pond water under each type of micros­cope.)

Functions of Compound Microscope Parts

Eyepiece (Ocular Lens): The lens you look through, typically with a magnif­ication of 10x.
Objective Lenses: These are found on the revolving nosepiece and typically include 4x, 10x, 40x, and 100x magnif­ica­tions.
Stage: The flat platform where you place your slides. It often has clips to hold the slide in place.
Stage Clips: These hold the slide in place on the stage.
Coarse Focus Knob: Used for focusing the specimen; moves the stage up and down in large increm­ents.
Fine Focus Knob:Used for fine-t­uning the focus of the specimen; moves the stage up and down in small increm­ents.
Light Source: Illumi­nates the specimen from below.
Diaphragm: Adjusts the amount of light that reaches the specimen.
Arm: Supports the tube and connects it to the base.
Base: The bottom support of the micros­cope.
Revolving Nosepiece: Holds the objective lenses and allows you to switch between them.
Condenser: Focuses light from the light source onto the specimen.
