Scientific Method
What is the first step in the scientific method?
Ask a question.
What are the two types of observation?
Qualitative Measurement and Quantitative Measurement.
What step of the scientific method do you predict a possible answer to a problem or a question?
Hypothesis.
How many independent variables are in an experiment?
One
Which step of the scientific method is missing: Question Formulate a Hypothesis ______________ Observe and Record Analyze Results Share the Results
Experiment.
What step of the scientific method do you test your hypothesis?
Experiment.
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/Outcome Variable
In which step of the scientific method do you use your information to draw conclusions about your experiment?
Analyze Results.
What step in the scientific method do you make careful observations and write down what happens?
Observe and Record.
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/Test Variable
Can a hypothesis ever be wrong? Explain
No. Even if your hypothesis is not supported, you are still learning.
In which step of the scientific method do you present your experiment, observations and conclusions to others?
Share Results.
Blue, rough, metal are all examples of what type of observation?
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 need to be kept the same throughout?
Constants
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.
What is Question, Hypothesis, Experiment, Observe and Record, Analyze Results, Share Results.
4 feet long with 24 buttons are both examples of what type of observation?
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 constant in this experiment be?
Using the same potting soil, making sure both plants have an equal amount of light etc.
