What is the power of the eyepiece | 10X |
What is the greatest magnification for Low. | 40X (10 x 4=40X) |
What is the greatest magnification for medium | 100X (10 x 10=100X) |
What is the greatest magnification for high | 400X (10 x 40=400X) |
What identifies a compound microscope | They have two lenses |
What is the proper way to carry a microscope | With two hands - one on the arm and one on the base |
If you are looking at a paramecium through the microscope and it moves left out of the field of view, which way did it actually move | It moved right |
What if it moved down | It moved up |
AS you move from low to medium and finally high power, how much of the specimen are you actually seeing each time if it is low power | you see more of the specimen with less detail |
As you move from low to medium and finally to high power, how much of the specimen are you actually seeing each time if it is high power | you see less of the specimen with more detail |
Your field of view is very dark. What part of the microscope do you adjust to make it lighter | Diaphragm |
How do you make a wet mount slide | -Put specimen on slide
-Place drop of water on the specimen
-Cover with coverslip
-Press coverslip to remove air bubbles |
What do you use to focus first | Coarse Adjustment knob |
What do you use to focus second | Fine Adjustment knob |
What is a variable | Any factor that can affect an experiment (ie. variables for plants could include: water, light, soil, etc) |
Why is a variable important when performing an experiment? Use the terms controlled and experimental in your answer | All variables must be the same between the control group and the experimental group except for the one variable being tested. |
Which parts of the lab do you write before the experiment | -Problem
-Hypothesis
-Materials
-Procedure |
Which parts of the lab do you write after the experiment | Data and conclusion |
Describe 3 questions you might be asked in the conclusion of a lab | -What is the answer to the problem question
-Was the hypothesis supported? How do you know
-Was the experiment controlled?
-How do you know the experiment was controlled or not controlled
-Why do you think the results turned out the way they did
-Why |
Can you have an experiment with 3 variables.
Why or why not? | No. If more than one variable was changed then you would not know which variable was important and why it was important |
