The most common type of modern microscope is called a compound microscope. They have two systems of lenses, one is the eyepiece and the other is comprised of one or more objective lenses. This type of microscope has become so advanced that some are capable of magnifying up to 1000 times! Microscopes are used in almost all types of scientific research, and this quiz game will help you learn their 12 major components. When you work with one of these specialized tools, you’ll want to know which adjustment controls the course focus, and which is for fine focus. What holds the slide on the stage? The stage clips, of course! Use this science quiz game to make learning the parts of a microscope easy.

The game Microscope Components is available in the following 3 languages:

Eyepiece Lens - This is the lens closest to your eye. It usually has a magnification of x10., Objective Lens - There are three lenses of different strengths which can be used to magnify the image more clearly., Stage - This is the place where you put a microscope slide. Clips hold the slide in place., Diaphragm - Controls the amount of light that goes onto the microscope slide., Light - The light source projects light onto the microscope slide. It can be a mirror or an electric bulb., Base - This is very heavy to keep the microscope from falling over., Arm - This holds the microscope slide on the stage., Fine Focus Knob - This is used to focus the image, so it is very sharp and clear., Coarse Focus Knob - This is used to focus the image so that you can see it clearly.,
