What is Qualitative Data and Quantitative Data.
What step of the scientific method do you predict a possible answer to a problem or a question?
What is Hypothesis.
What are the two types of variables stated in a hypothesis?
What is Independent and Dependent.
Step 1 of the scientific method but always be written as a....
? Question ?
*punctuation matters!!
What step in the scientific method do you gather more information?
#2 Research
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.
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?
Independent Variable.
Which step of the scientific method is missing: Problem, Research, Hypothesis ______________, Analysis/ Results, Conclusion.
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.
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 is the variable that is not being studied because it is used for comparisons. They are also held constant/consistent so that they do not influence the experimental outcome...
Control 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.
What number/step of the scientific method do you follow numbered directions to test your hypothesis?
#4 Experiment/Procedure
This type of data is measureable?
What is Quantitative Measurement.
Putting my plant in the closet will decrease its chance of living. What is wrong with this hypothesis?
it is missing "If" and "Then" and "Because"
What is the responding variable or variable you are testing, measuring, observing? The Data...
Dependent Variable.
In which step of the scientific method do you use your information to make inferences about your experiment?
Analysis/ Results.
List all six steps of the scientific method.
1.Problem 2. Research 3. Hypothesis, 4. Experiment/Procedure 5. Analysis/Results 6. 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?
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 eat candy all day on Halloween, then you will get an upset stomach, because of the sugar rush and crash.
Independent- amount of candy
Dependent- level of sickness/upset stomach
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.
