1. What invention helped with many discoveries in science?
Agenda for Thursday Sept 8th
Microscopes
Lab
Learning Objectives
Identify microscope parts and know their function
Compute magnification for a microscope
Measure the size (in microns) of objects under the microscope

3. Basic Rules Carry using arm and base Flat Surface
Adjust light using diaphragm
Use stage clips
Focus with course adjustment on low and medium power only!
High Power use fine adjustment only

4. What is the function of the diaphragm on the microscope?
Agenda for Friday Sept 4th
Microscope lab

5. Magnification
Total magnification = eyepiece magnification X objective magnification
Eyepiece is 10x and objective is 10x what is total magnificaion?

6. How to make a wet mount slide
Specimen on slide
Drop of water/stain
Cover slip on slide

7. Calculate Field of View
Clear Ruler
Determine how many millimeters across
Convert to micrometers
1mm=1000μm
So: if 1.5 mm across then field of view is
1.5mm x 1000 μm/1mm = 1500 μm

8. Calculate Size of Specimen
Figure out how many will fit across the field of view (estimate)
Divide field of view length by how many fit across
If 8 fit across and field of view is 800 μm then specimen is 100 μm
800 μm/8 = 100 μm

9. Remember! Carry using arm and base Flat Surface
Adjust light using diaphragm
Use stage clips
ONLY USE FINE ADJUSTMENT ON HIGH POWER!

10. Objectives Identify microscope parts and know their function
Compute magnification for a microscope
Measure the size (in microns) of objects under the microscope

11. What is the total magnification if you have a 10x eyepiece and are using a 40x objective?
Agenda for Monday Sept 12th
Microscope Quiz
Microscope Lab
Learning Objectives
