Scientific Variables
Any factor, trait, or condition that can exist in differing amounts or types
Variables
To make sure
insure
How many times were the bottle flipped?
20 times
Optimum
the best
How repeatable an experiment is
Velocity
Speed
Clear, Red, yellow, blue and black
The colours of the ice
Array
A series of things
The 3 types of variables are....
Dependent, Independent, controlled
information
Data
25, 50, 75, 100
percentage of water in the bottle
Different
For an experiment to be valid.....
reduce the variability
Reliable
consistently good
The independent variable is....
The colour of the ice
Utilise
Use
the variable that is changed
independent variable
to change
altered
What is the independent variable?
the amount of water in the bottle
Flipped
Turned over
No
Repeatable
Can happen again easily
The dependent variable is..
How quickly the ice melted
Assortment
A Series of Things
the variable that responds to the independent variable
Dependent variable
anything that you can change
variable
What was the dependent variable?
amount of successful bottle flips
Endeavour
Journey or task
A person did the experiment using the same person and conditions. Is that experiment valid?
Yes
Variability
How different something can be
A hypothesis is.....
prediction made before the experiment based on observations and assumptions the person has
Assumptions
A guess without proof
Controlled variable
trait
What was the controlled variable?
the bottle used
Proficiency
How good you are at something
We changed the balloons every trial. We also had finish lines with different lengths, which affected how soon the balloon can reach the end.
Is this experiment valid or reliable?
No
Attempt
Trial
If the ice had a darker colour......
then the ice would melt faster
Conjecture
Guess based from what you already know
