Virtual Microscope Lab

Part 1.

1. When you begin the condenser knob should be all the way up.
2. Start with the 4x objective in place.
3. Raise the rheostat to 10.
4. Move slide using the X Y controls.
5. You close the iris before looking into the microscope as to not blind ourselves.
6. You eyes should be three quarters on an inch away from the oculars works best.
7. Increase light by opening the iris.
8. Highest magnifying objective is called oil immersion
9. The oil immersion procedure is done by placing a drop of oil in the center of the specimen between the 40x and 100x objective.
10. Clean slides with Chemwipes, clean objectives by turning out and clean with lens paper.
11. To successfully shut down the microscope you remove the slide and clean it. Place the objective back to 4x, close the iris and turn down the rheostat to 1. Finally you can turn off the microscope.


Part 2.

1.The 4x objective must be in place when you remove a slide and place a new slide on the stage of your scope.
2. You must use the 4x objective when you first start looking at a slide.
3. You must adjust the amount of light when looking at thin and/or transparent cells or tissue sections such as onion or amoeba cells.
4. You can adjust the rheostat and iris control to decrease light intensity and the amount of light passing through the scope.
5. The 4x objective allows you to see the largest are of the object that you are viewing.
6. You are magnifying something by 100x when using the 10x oculars and 10x objectives.
7. You are magnifying something 40x when using the 10x oculars and 4x objectives.
8. The course control knob is first used when you begin to look at a slide.
9. You need to adjust the oculars if you an see two overlapping circus with part of the objective in each circle.

Part 3.

Bacterial capsule is a pink oval with silver color cells inside.
The cheek smear has scattered cells around it.
The letter “e” is lower case and upside down.
The onion root tip is a long cone shape.
