Scientific Method
The first step in the scientific method?
What is Question?
The difference between the two types of observations.
What is Quantitative involves numbers?
The step of the scientific method where you make an If/Then statement.
What is the Hypothesis?
The two types of variables stated in a hypothesis.
What is Independent and Dependent?
This variable goes on the Y axis.
What is the dependent variable?
The step where you carry out your experiment.
What is Test the hypothesis?
This type of observation is measurable.
What is Quantitative 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"
The responding variable or factor that may or may not change due to manipulation.
What is Dependent Variable?
The step of the scientific method where you use your information to draw conclusions about your experiment.
What is Analyze Results?
The step in the scientific method where you record and organize your data.
What is Observe, Record, and Analyze?
This type of observation 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.
The term we use to describe the variable or factor that the experimenter intentionally changes.
What is Independent Variable?
The ________________ involves a series of steps that are used to make a scientific investigation.
What is Scientific Method?
The step of the scientific method where you summarize what you have learned.
What is Draw Conclusions?
Blue, rough, and metal are all examples of of this type of observation.
What is 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.
What is...If you increase the number of cigarettes you smoke, then you will increase your chance of getting lung cancer.
In an experiment these variables are not being studied and are kept the same so that they do not influence the experimental outcome.
What is the constant variable?
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.
The step where you research your topic.
What is Collect Information?
Four feet long with twenty-four buttons are both examples of this 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.
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 be a constant variable in this experiment?
What is... using the same potting soil, making sure both plants have an equal amount of light, etc?
