1
What is the independent variable?
The variable measured
The outcome
When you hold something constant
The one variable that is changed
2
All of these need to be part of any graph you create EXCEPT
Equal intervals and accurate data
Pretty colors
A title
Labeled axis with units
3
The group which
contains the independent
variable. Scientist changes something in this group to test their hypothesis.
Control Group
Independent Group
Experimental Group
Constant Group
4
This is when you state whether your hypothesis was correct, your errors, and what you do next.
Problem
Graph
Conclusion
Procedure
5
A variable (often denoted by x ) whose variation does not depend on that of another. The thing a scientist changes.
Control Group
Independent Variable
dependent Variable
Constants
6
What is the first thing you do if you are in the lab and you spill chemicals on your hands?
Scream
Get the fire extinguisher
Tell the instructor
Pull the chemical shower
7
A control group helps an experiment because it give the scientist
More participants
A group to compare experimental results to
None of the above
More work
8
The effect of amount of light on plant growth. What is the IV?
The amount of Soil
Amount of Light
The type of plant
Plant growth
9
True or False: Only people with degrees in science can conduct experiments and be valid.
True
False
10
The purpose of a procedure is to....
Make sure the hypothesis is correct.
Show others the steps you took to do the experiment.
Keep other people from copying
Make you do more writing
11
What is the difference between the experimental group and the control group
The experimental group includes the independent variable (IV)
The experimental group gets results fast
The experimental group is the control group
The experimental group is larger than the other
12
The variable that changes as a result of the independent variable. It is what is measured or observed in the experiment.
Constants
Dependent Variable
Controls
Independent Variable
13
The dependent variable is the.....
Is known before the experiment
Stays the same throughout the experiment
The variable measured, if other words the results.
Changed by the scientist
14
A good hypothesis should
Always be 100% testable
Make a good experiment
Be correct in the end
State - if....then...because....
15
How is a control or controlled variable different than the dependent variable? Typically referred to as constants.
Control variables are the same as dependent variables.
Control variables are what the scientist is testing.
Control Variables remain unchanged in both groups.
Control variables are the outcome.
16
What do you need in order to begin the scientific method or take on an engineering challenge?
A problem/question
Tools
Hands
A degree
17

1. Guess 2. Research 3. reinvent the experiment 4. Bet 5. Pick a winner
1. wing it 2. try hard 3. try anything 4. report it 5. conclusion
1. Observation 2. Hypothesis 3. Experiement 4. Analysis 5. Conclusions
None of the above
18
A drug company tests their drug, in their own lab with patients they hand select. Why be skeptical?
There is bias
They are always only out for profit
They did control enough variables
They are not scientists
19
Which scenario would be the most credible and accurate?
Not controlling variables and doing one trial.
Controlling all variables and doing one trial
Not controlling variables and doing 100 trials
Controlling variables and doing 100 trials
20
Roosevelt football team wants to know if protein shakes makes you stronger. What's the DV here?
Shakes
Player Strength
The age of players
The coach
21
This is the group which serves as the basis of
comparison. It is the group which the scientists do not “experiment” on.
Dependent Variable
Control Group
Experimental Group
Independent Variable
22
Factors in an experiment that remain the same for both the experimental group and control group.
Independent Variable
Dependent variable
Constants
Experimental factors
23
Select the correctly written hypothesis
If more light is added then more growth will result because of extra energy
The more the growth the more light and vice versa.
What happens if no light is added?
More light added will always result in more growth.
24

line graph
All the above
Results table and graph
Bar graph
