Scientific Inquiry Steps
The step after you ask a question about something in nature.
What is make a make/develop a hypothesis
This is the variable that a scientisit observes and measures
What is the Dependent Varieable
What effect does light have on plant growth?
If a plant receives less light, then the plant will not grow well.
If a plant receives adequate light, then the plant will grow well.
If Miracle Grow is used, then plants will grow bigger.
IV = Miracle Grow
DV = plants grow bigger
What does CER stand for?
Claim
Evidence
Reasoning
Ask a question, identify a problem, or make an observation
What is the first step in Scientific Inquiry
A variable that does not receive the Independent Variable and stays the same throughout the experiment
What is the control (variable(s))
Will the apples be sweeter when the tree gets enough water?
If an apple tree gets enough water, then the apples will be sweeter.
or

If school buses are painted grey, then there will be more school bus accidents.
IV = color of school bus
DV = number of accidents involving a school bus
This is the BEST type of evidence
What are numbers
This is done while you do your experiment
collect data and make observations
the variable that the researcher manipulates in the experiment, that is being tested
What is the Independent Variable
Eating breakfast increases performance at school.

or
If you do not eat breakfast, then you will not perform well at school.
If students get 8 or more hours of sleep, then they will get better grades.

Does not include: because, I think, etc.
After analyzing your data you decide if it supports your hypothesis and you make a ________
conclusion

How does the number of coupons you use affect the amount of money you save?
IV = coupon use
DV = the amount of money you save
What is the role of the evidence?
To support the claim and prove it true
After you make your hypothesis you should do this
What is do your experiment
This is the "then" part of the hypothesis sometimes called the responding variable
What is the Dependent Variable
What effect does smiling have on a teacher giving homework?
If we smile more, then the teacher will give less homework.
How does the amount of time studying affect a student's test grades?
IV = amount of time studying
DV = student's test grades

To explain how the evidence supports the claim and makes it true.
