Scientific Method
What is the first step of the scientific method?
Observation
What are the two types of data?
Quantitative and Qualitative
What is...If I increase the amount of time I run, then my heartbeat will increase.
Independent and dependent
What step of the scientific method do you predict a possible answer to a problem or a question?
Hypothesis
The ________________ involves a series of steps that are used to investigate a natural occurrence.
scientific method
What step of the scientific method do you test your hypothesis?
Experiment
This type of data is measureable.
Quantitative
What is the responding variable or factor that may or may not change due to manipulation?
Dependent variable
Putting my plant in the closet will decrease it's chance of living. What is wrong with this hypothesis?
It's missing the If Then format
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.
What is the last step of the scientific method?
Retest or repeat
This type of data is describable.
Qualitative
Which variable do "I change"?
Independent Variable
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.
Thinking about the hypothesis: If soil temperatures rise, then plant growth will increase. What might a control in this experiment be?
using the same potting soil, making sure both plants have an equal amount of light etc.
List all seven steps of the scientific method.
Observation, Hypothesis, Experiment, Collect data, Analyze data, Form conclusion, Retest
4 feet long with 24 buttons are both examples of what type of observation?
Quantitative
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 or constant
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 variable in the following experiment: One cow is fed a growth hormone and another cow is not. After a year, both cows are weighed.

Dependent-weight
You use your 5 senses to make these
Observations
Blue, rough, metal are all examples of what type of observation?
Qualitative
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.
What is the difference between a theory and a hypothesis?
A theory is more supported and ties together multiple hypotheses
Find the independent and dependent variable for the following experiment: Bob studies for a test and Jackie does not. After the test they compare their scores.
Independent: Studying
Dependent: Score
