2
Which of the following is an example of an HYPOTHESIS?

Light or dark environments
When we expose bugs to light or dark, they will choose dark

False
7
What does it mean to say that Science is BIASED?
Scientists never make mistakes
Different ways of thinking b/c of experience
Scientists are very rigid in their thinking
Scientists are imperfect
8
How could you MEASURE whether a new drug helped people with asthma?
Ask the people being tested how they felt
No clue
Count how many pills people take
Track number of times an inhaler was used
9
Why is it important to have a control group when using the scientific method?
To keep everything the same
To get the best results
So you can control the results
To have something "normal" to compare the results to
10
Before you can perform an experiment, what step of the scientific method MUST you perform?
Analyze data
Form an hypothesis
Modify the experiment
Communicate results
11
How can you keep from making INCORRECT inferences in Science?
Have as many variables as possible
Lie, cheat and steal (please don't choose this one!)
Communicate as much as possible
Make as many observations as possible
12
Why do we usually repeat experiments many times in Science before drawing a conclusion?
So we aren't biased
Scientists get more money that way!
Scientists are bored
Every time we experiment, we get more information
13
What does it mean to say that Science is UNCERTAIN?
We can never know anything
Our understanding is always changing
Scientists are liars
I don't know
14
Why don't you want to test more than one variable at a time in Science?
You won't know what actually causes the results
It would be too confusing
Squirrel!
You can't control more than two variables
