Scientific Method
What is the first step in the scientific method?
Defining 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.
What are the two types of variables stated in a hypothesis?
Independent and Dependent.
Which step of the scientific method is missing: Question, Formulate a Hypothesis, ______________, Analyze Results, Share the Results
Experiment.
What step of the scientific method do you test your hypothesis?
Experiment.
This type of observation is measurable.
Quantitative Measurement.
What is the sentence structure for a hypothesis?
"If {this happens} then {this will happen}."
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 to draw conclusions about your experiment?
Analyze Results.
What do you call the idea/question that you explore with experimentation?
The hypothesis
This type of observation is describable.
Qualitative 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"
What is the term we use to describe the manipulated variable or factor that the experimenter intentionally changes?
Independent Variable.
The ________________ involves a series of steps that are used to investigate a natural occurrence.
Scientific Method.
In which step of the scientific method do you present your experiment, observations and conclusions to others?
Sharing Results.
Blue, rough, metal are all examples of what type of observation?
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.
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.
What is...Independent-soil temperatures, Dependent-plant growth.
List all five steps of the scientific method.
What is Question, Hypothesis, Experiment, Analyze Results, Share Results.
4 feet long with 24 buttons are 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.
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?
For example: using the same potting soil, making sure both plants have an equal amount of light, etc.
