| what is the proper way to hold a microscope> | with one hand, grip the arm, and place the other hand under the base for support. |
| what is the function of the eyepiece on a microscope> | it is was you look through to see the slide and it magnifys the slide. |
| what is the function of the nosepiece on a microscope> | it is used to hold the objectives and turn them around |
| what do the objectives do on a microscope> | they are used to magnify the slide with different magnifications(low,medium,high). |
| what is the stage on a microscope> | it is where you place the slide to view it under the microscope. |
| on a microscope, what is the light source> | the place at the bottom of the microscope where the light used to see the slide comes from. |
| what is the base of a microscope> | this part provides support for the microscope. |
| what does the course adjustment knob do on a microscope> | this focuses the image under low power. |
| what does the fine adjustment knob do on a microscope? | this sharpens the image under high magnification. |
| what is the body tube on a microscope> | it is the part that connects the eyepiece and the nosepiece. |
