Scientific Method
What is the first step in the scientific method?
Question/Problem
What are the two types of measurements we use when collecting data?
Qualitative Measurement and Quantitative Measurement.
What step of the scientific method do you predict a possible answer to a problem or a question?
Hypothesis
What are the two types of variables stated in a hypothesis?
Independent and Dependent Variables
Which step of the scientific method is missing: Ask a Question, gather information, create a Hypothesis ______________, Analyze Data, Summarize your findings
Test - Test your hypothesis
What step of the scientific method do you test your hypothesis?
Test
This type of observation is measureable.
Quantitative Measurement.
Putting my plant in the closet will decrease it's chance of living. What is wrong with this hypothesis?
It is missing "If" and "Then"
What is the responding variable or factor that may or may not change due to manipulation?
Dependent Variable.
In which step of the scientific method do you use your information from your test to draw conclusions about your experiment?
Analyze Data
What step in the scientific method do you think about what you (or others) already know?
Gather Information
This type of observation is describable.
Qualitative Measurement.
If you drink more milk will you get stronger bones? State a good hypothesis for this question.
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?
Independent Variable.
The ________________ is a specific and logical sequence of step used to learn new things or to answer questions.
Scientific Method.
In which step of the scientific method do you look at the results of your test?
Analyze Data
Blue, rough, metal are all examples of what type of measurement?
Qualitative Measurement.
I wonder if you smoke more cigarettes, will you have a better chance of getting lung cancer? State a good hypothesis for this question.
If you increase the number of cigarettes you smoke, then you will increase your chance of getting lung cancer.
In an experiment what are the variables that are not being studied that are held constant so that they do not influence the experimental outcome called?
Control
List the independent and dependent variables in the following hypothesis. If soil temperatures rise, then plant growth will increase.
Independent-soil temperatures, Dependent-plant growth.
List all six steps of the scientific method.
Question/Problem, Gather Information, Hypothesis, Test, Analyze Data, and Conclusion.
4 feet long with 24 buttons are both examples of what type of measurement?
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?
If I increase the amount of time I run, then my heartbeat will increase.
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.
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?
Using the same potting soil, making sure both plants have an equal amount of light etc.
