Scientific Method
What step of the scientific method do you predict a possible answer to a problem or a question?
Construct a hypothesis.
This type of observation is measureable.
What is Quantitative Measurement.
Putting my plant in the closet will decrease it's chance of living. What is wrong with this hypothesis?
Use the independent variable and dependent variable in your hypothesis.
"if I remove the sunlight, then a plant cannot survive"
What is the responding variable or factor that may or may not change due to manipulation?
What is Dependent Variable.
Question: Is milk good for 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?
What is Independent Variable.
I wonder if smoking affects the heath of your lungs? State a good hypothesis for this question.
E.g. If you increase the number of cigarettes you smoke, then you will increase your chance of getting lung disease.
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?
What is Controlled variable.
List all six steps of the scientific method.
What is Ask a Question, Formulate a hypothesis, Experiment, Observe and Record, Analyze Results, Share Results.
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 controlled variable in this experiment be?
What is... using the same potting soil, making sure both plants have an equal amount of light etc.
