Scientific Method
What is a controlled experiment?
Tests only 1 variable
What can we do if the FOV is too dark?
Adjust the diaphragm
How many variable shoud you test at one time on a controlled experiment?
1
How do we calculate total magnification?
Eyepiece x Objective lens
When do we use a cover slip?
When making a wet mount
Which is the variable we are measuring?
What is Dependent Variable.
Is it better to have a small or large sample size? Why?
Larger sample size because the results will e more valid
What is the relationship between the control group and the experimental group?
Identical in all ways but 1 (variable being tested)
What would the letter "e" look like under the microscope?
Upside down and backwards
What is the term we use to describe what we are testing in an experiment
What is Independent Variable.
What would make an experimant more valid?
Repeat many times and get the same results
What is the highest magnification on out compound microscopes?
400x
In an experiment what are the variables that are not being studied that are held constant so that they do not influence the experimental outcome called?
What is Controls (constants).
List all seven steps of the scientific method.
State the problem, Research, Hypothesis, Experiment, Collect and Analyze Results, Conclusion, Share Results.
If you physically moved a slide on the micrsope left and up, how would the specimen move?
right and down
Find the independent and dependent variables in the following experiment: If you increase the number of times you practice shooting free-throws, then you will increase your chances of making a basket every time.
What is Independent- practice shooting free throws, Dependent- making baskets.
