What is the one variable that is changed in an experiment; The one that we are testing?
Manipulated Variable
100
The Manipulated Variable is the________ and
the Responding Variable is the __________in a hypothesis.
What is M.V=Cause and R.V=Effect
100
A hypothesis needs what three words?
What is if, then, because
100
In a controlled experiment, how many variables are being tested?
What is only one variable
200
What is a possible explanation for a set of observations; Must be testable
What is Hypothesis
200
Identify the M.V:
If I give my cats vitamins then they will be healthy because vitamins make people healthy.
What is vitamins is the Manipulated Variable
200
Your hypothesis is based on a set of observations and _____________that can be testable
What is Investigative question/ Problem
200
There are variables that need to be controlled in an experiment that must be kept ________________to make the experiment fair.
What is the same
300
What do we measure in an experiment; the response?
What is Responding Variable
300
Identify M.V and R.V in the Hypothesis:
If I add water to my P.T, then it will fall faster because the extra weight will pull it to the ground faster.
What is water=Manipulated Variable........
What is fall faster= Responding Variable
300
Identify the missing words.
1)If=______=Manipulated Variable.....
2)Then=Effect=____________.......
3)Because/__________
What is 1)Cause
2)Responding Variable
3)Explanation.
300
Identify variables that need to be controlled:
"Does sugar in water make flowers live longer?"
What is the
1)type of flower
2)# of flowers
3)temperature of climate
400
Variable
What is factors that can change in an experiment; must be kept the same.
400
Identify the cause and effect in hypothesis:
If I space my plants further apart, then it will grow better because they have more room to spread out and grow.
What is spacing plants further apart=cause.......
What is grow better=effect
400
Write a hypothesis for the investigative question:
"How does weight affect the speed at which an object falls?" (P.T Lab)
What is..
If I place more weight on an object/ P.T then it will fall faster because the heavier the object the faster it will fall.
400
List three variables that need to be controlled:
"If I give plants water everyday, then they will die because they have too much water".
What is...
1) Type of plant
2) temperature of climate
3) Amount of sunlight
500
Controlled experiment
What is an experiment in which only one variable is tested.
500
In the scenario with the two cats testing vitamins, identify the manipulated and responding variables.
What is Vitamins=M.V......
What is cat being healthier= R.V
500
Write a hypothesis based on the investigative question:
"What if we used water instead of milk for the milk lab?"
What is....
If we used water instead of milk in the lab then it would have the same affect because I think water has the same level of density as milk.
500
In the P.T lab, What were variables that needed to be controlled?
What is...
1)where paper clip was placed
2)The height
3) The position of the P.T.
4)Time, in seconds
