Microscope Lab #2
Microscope Lab #3
Challenge 1
Challenge 2
100
These two things had to happen in order for the liquid to change color
What is oxygen (air) and shaking
100
Our microscope has this type of diaphragm.
What is lever
100
How did the "e" appear under the microscope
What is upside down
100
Explain the phrase "solving a problem by using the scientific method"
What is using a planned set of steps to answer a question
100
Give the colors for each objective lens.
What is scanning = red, low = yellow, high = blue
200
This is why liquid was removed from flask B.
What is so air could mix in with the liquid.
200
We always find objects first using this objective power.
What is scanning
200
When moving an object to the left, it moves this way when you look at it.
What is right
200
What was the original problem in the scientific method lab?
What is are the liquids the same?
200
Why is a coverslip put on at a 45 degree angle
What is to avoid getting air bubbles
300
What happened to the liquid as the number of shakes increased?
What is stayed blue longer
300
The stage moves this direction when you turn the coarse objective away from you
What is down
300
True or False: You could see both strings under low power.
What is TRUE
300
Why is it better to solve a problem by experimenting than guessing?
What is you can get data/evidence to support your answer with an experiment
300
If you see 40 cells under low power, how many would you see under high power?
What is 10 (you see 4x more under low power than high power)
400
What were the independent and dependent variables in experiment #1
What is independent = amount of liquid; dependent = color change
400
True or False: fine adjustment can be used on any of the objective powers
What is TRUE!
400
Why do we stain a slide
What is make the image darker/more defined/more contrast
400
List 2 conditions that could have affected your results from the scientific method lab.
What is didn't shake with same force each time, stop watch not started/stopped at the right time, different people shook the flasks, spilled some liquid, not exactly the same amount, hit the table
400
What are the functions of the stage clips, stage opening, and stage?
What is stage clips = hold a slide in place; stage opening = allows light to pass through the stage; stage = holds the slide
500
What were the independent and dependent variables in experiment 3
What is independent = # of shakes; dependent = time stayed blue
500
Why do you look to the side when changing from one objective to another?
What is to make sure the lens doesn't hit the slide
500
Why could you see more potato cells under low power than high power?
What is more area to see under low power so more potato cells
500
Explain the proper way to shake a flask.
What is paper towel on top, thumb over paper towel and stopper, hand around the bottom, shake up and down with one good shake
500
When looking at an image under a microscope, and it is in the top left corner, how do you move the slide so it is in the middle?
What is move the slide up and to the right
