100
I will collect data from this variable.
It is like the effect in cause and effect.
Dependent Variable
100
I can make changes to this variable.
This is the only thing that should be changed in an experiment.
It is like the cause in cause and effect
What is Independent Variable
100
The proper method for smelling something in the laboratory
What is "wafting"
200
Use of your 5 senses
Observations
200
Charts and graphs
Analyze Data
200
Variable that does not change in an experiment
What is Constant
200
The group that is observed but not change
What is Control Group
200
Used to hold something hot or cold in the lab
What is tongs or gloves?
300
Written as if/then statement
What is a hypothesis?
300
The step that you go back to when the hypothesis is found not to be supported in the conclusion
Step 3 or Hypothesis
300
Ivan and Braxton want to know if a stretching a rubber band at different lengths affects how far the rubber band will fly.
What is the IV?
Different lengths of rubber band (Stretching)

Carie and Heather wanted to know if the size of a coin will affect the number of drops of water it can hold. So they used a dropper to place water on a quarter, nickel, and penny.
DV?
the number of drops of water it can hold

A student wanted to test how the mass of a paper airplane affected the distance it would fly. Paper clips were added before each test flight. As each paper clip was added, the plane was tested to determine how far it would fly.
Constant?

What is step 7 and why is it so important?
Share/Communicate. So that other scientists can also repeat the same experiment
500
An experiment was performed to determine how the amount of coffee grounds could affect the taste of coffee. The same kind of coffee, the same percolator, the same amount and type of water, the same perking time, and the same electrical sources were used.
IV
DV
Constants (3)
IV- Amount of coffee grounds
DV- taste of coffee
Constants: percolator; water; perk time; electrical source

Explain the difference between control group and experimental group
What is one group no change is done to (control group) change is applied to the experimental group
