Correct format
Measurable
Contains both IV and DV
What are the two types of variables stated in a hypothesis?
What are Independent and Dependent.
What tool is used to measure mass?
Which step of the scientific method is when you collect information from your experiment and put it in charts and graphs?
What is "Data/Results?"
Blue, rough, metal are all examples of what type of observation when describing a bicycle?
What is Qualitative Measurement?
Putting my plant in the closet will decrease it's chance of living. What is wrong with this hypothesis?
What is... it is missing "If" and "Then"
What is the responding variable or part of the experiment that measures the results?
What is the Dependent Variable?
Two parts:
Which measurement tells us -
*how much matter an object is made up of?
*how much space an object takes up?
In order:
What are mass and volume?
Which step in the scientific method is when you use an if/then statement to predict the outcome of your experiment?
What is "Hypothesis?"
Inference, Quantitative Observation, or Qualitative Observation?
The dog is barking because he sees a squirrel.
What is Inference?
Does changing how much milk you drink affect how strong your bones get? State a good hypothesis for this question.
What is...If you increase the amount of milk you drink, then you will increase the strength of your bones.
What is the term we use to describe the manipulated variable or factor that the experimenter intentionally changes?
What is Independent Variable.
How do you measure the volume of an oddly shaped object like a rock or a nail?
What is water displacement?
In which TWO steps of the scientific method do you list all the items needed to do the experiment and then list the step-by-step directions of how to do it? (in the correct order)
What are "Materials" and "Procedures?"
Inference, Quantitative Observation, or Qualitative Observation?
John's team scored twice as many points as Colton's team.
What is Quantitative Observation?
If I change the amount of fertilizer in a plant, will it affect the mass of my plant? State a good hypothesis for this question.
What is...If you add more fertilizer to a plant, then it will have a greater mass.

What is Control.

What is Question, Hypothesis, Materials, Procedures, Data/Results, and Conclusion?
Give TWO examples of Quantitative Observation
List two things that are either counted, measured, or compared
Read the following experiment and state a good hypothesis. I am doing a test to see if there is a connection between how long you run and how fast your heart beats. I will be performing an experiment where a person will run for a 1 minute and I will check their heartbeat. Then they will run for 2 minutes and I will check their heart rate. I will do this up to 6 minutes and see if there is a connection. What do you think my hypothesis should be?
What is...If I increase the amount of time I run, then my heartbeat will increase.
BONUS - name the independent variable, dependent variable, and at least 3 controlled variables (for 100 pts. each) - total possible of 500 pts.
Find the independent and dependent variables in the following hypothesis: If you increase the amount of time you practice shooting free-throws, then you will increase how many baskets you make out of 20 attempts.
What is Independent- amount of time you practice shooting free throws, Dependent- how many baskets you make out of 20
