1
Why is the experimental group important?
Because it provides us with more data about the subjects
Because it provides more information about the trials
Because the group is contrasting to the control group
It serves as the independent variable
2
What is a theory?
Statement based on repeated experimental experimental observation
Generalized concept or principle
An explanation of a natural phenomenon
Indisputable observation
3
What is a principle?
Statement based on repeated experimental observations
Indisputable observations
Generalized concept or principle
An explanation of a natural phenomenon
4
What do bad bacteria do?
Unnecessary
They may cause infection, make us sick or even kill you
Both are correct
Beneficial to the body and enhance health
5
What is a dependent variable?
A hypothesis.
A prediction.
What changes response to the independent variable.
A control group.
6
How do you use a graduated cylinder?
I did not pay attention
Look for the center dip
The height point of water
graduated cylinders are not for measuring
7
What is the first step of the scientific method?
Gather information
Draw a conclusion
Make an observation
Make a hypothesis
8
What do good Bacteria do?
Unnecessary
They may cause infection, make us sick or even kill you
Both are correct
Beneficial to the body and enhance health
9
What is a control group?
Conclusion
The group that you don't change in an experiment
What is being measured
Analyzing data
10
What is biology?
The study of Earth.
The study of rocks
The study of words
The study of life and living organisms.
11
What Variable is being measured?
The results
A hypothesis
Independent Variable
Dependent Variable
12
What is precise?
Analyzing data
A prediction
How close your experiment are to each other
How close is your measurement to the answer
13
Why do you need a control group?
So that you can control the experiment
You don't need it
To see the difference between what changes
To see what happens in experiement
14
What is Science?
The study of living organisms.
Knowledge based on people.
The body of knowledge based on the study of nature.
The mind of knowledge based on experiments.
15
What is an independent variable?
It is a variable whose variation does not depend on another
Stays the same in a response
16
What does precise mean ?
How close your measurements are to each other
2 numbers away
B and c
How close your measurement is to the correct value
17
Why is the control group important?
A&B
So you can compare the results of the other groups.
So you know exactly what is affecting the thing being experimented on.
It's not.
18
What's an experimental group?
Groups that are being tested
A scientific inquiry
A group that's being compared
Something that's deliberately changing
19
What is a hypothesis?
A random guess
What .changes in the response
Dependent variable
testable prediction based on observations
20
What is a controls group
Has many changes done
A group that is not altered or changed
Is a different type of test subject
Is different than the other test subjects
21
What gets changed in an experiment?
The independent variable
The dependent variable
The control group
Nothing
22
Whats a experimental group?
Groups that are changing
Groups that are being tested.
Groups that are staying the same
23
What is a law?
Describes observations
Describes qualities
Generalized concept or principle
An educated guess
24
What is a fact?
Statement based on repeated experimental observations
Indisputable observations
An explanation of a natural phenomenon
Generalized concept or principle
25
what is Dependant variable?
The independent variable
Changes or manipulates the study
On the X axis
What changes in response
26
What is a Independent variable?
what changes in response
What researcher changes or manipulates
The dependent variable
The Y axis is
