What is Quantitative Measurement.
Putting my plant in the closet will decrease its chance of living. What is wrong with this hypothesis?
What is... it is missing "If" and "Then" and "Because"
What is the responding variable or variable you are testing, measuring, observing?
What is Dependent Variable.
In which step of the scientific method do you use your information to make inferences about your experiment?
What is Analysis/ Results.
What step in the scientific method do you make careful observations and write down what happens?
What is Experiment
This type of data is describable?
What is Qualitative Measurement.
If you drink more milk will you get stronger bones? 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 because of the calcium.
What is the term we use to describe the manipulated variable or the variable you change intentionally to see how it effects other variables?
What is Independent Variable.
Which step of the scientific method is missing: Problem, Research, Hypothesis ______________, Analysis/ Results, Conclusion.
What is Experiment/Procedure
In which step of the scientific method do you go through your data, observations, and communicate those results?
What is Analysis/Results
Blue, rough, metal are all examples of what type of observation?
What is Qualitative Measurement.
I wonder if you drink a lot caffeine will that stunt your growth and then you won't grow as tall? State a good hypothesis for this question.
What is...If you increase the amount of caffeine you drink, then you will not grow as tall because the caffeine limited your height potential.
In an experiment what are the variables that are not being studied and used for comparisons. They are also held constant so that they do not influence the experimental outcome called?
What is Control.
List the independent and dependent variables in the following hypothesis. If soil temperatures rise, then plant growth will increase.
What is...Independent-soil temperatures, Dependent-plant growth.
List all six steps of the scientific method.
What is Problem, Research, Hypothesis, Experiment/Procedure, Analysis/Results, Conclusion.
4 feet long with 24 buttons are both examples of what type of observation?
What is Quantitative Measurement.
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 because you are using a lot of energy.
Find the independent and dependent variables in the following experiment: If you increase the number of times you practice shooting free-throws, then you will increase your chances of making a basket every time.
What is Independent- practice shooting free throws, Dependent- making baskets.
Thinking about the hypothesis: If soil temperatures rise, then plant growth will increase. What might a control in this experiment be?
What is... using the same potting soil, making sure both plants have an equal amount of light etc.
