LESSON 2- INTRO TO MICROSCOPES

4. Today we are going to..
Talk about cells
Learn how to use microscopes
Label the microscope

5. What are cells?

6. What are cells? Cells are the basic units of life
There is no living thing smaller

What do each of these photos have in common?

8. Microscopes Cells are far too small to see with our naked eye
We can use MICROSCOPES to MAGNIFY the cell so we can see all the different parts of it

9. Labelling the microscope
The eyepiece lens The part of the microscope we look through- it usually has a magnification of x10

10. Labelling the microscope
The objective lenses Different lenses with different magnifications to allow us to look closer (zoom) at our slides

11. Labelling the microscope
The stage The slide is placed upon the stage

12. Labelling the microscope
The stage clips Holds the slide in place

13. Labelling the microscope
Light source (mirror) Passes light through the slide and specimen

14. Labelling the microscope
Focusing dials Focuses the image to give a clear picture
