What is the difference between qualitative and quantitative data?
Qualitative data is derived from observations using the five senses. Quantitative data is derived from measurements.

Missing "If"..."Then"..."Because"...
200
Which variable may or may not change due to manipulation?
Outcome Variable
200
Which step of the scientific method allows the scientist to reach a conclusion?
Analyze Results
300
During which step does the scientist collect observations from the experiment?
Observe, Record, and Analyze Data
300
Why do scientist only manipulate one variable at a time?
To know which variable directly influenced the outcome of the investigation.

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 milk contains calcium which increases bone strength.
300

400
Why should a scientist conduct multiple trials?
In order to attain reliable results.

I wonder if you smoke more cigarettes, will you have a better chance of getting lung cancer? State a good hypothesis for this question.
If you increase the number of cigarettes you smoke, then you will increase your chance of getting lung cancer because cigarettes contain harmful carcinogens.
400
In an experiment, which variables are not being studied and are kept the same so that they do not influence the experimental outcome?
Constant Variable

List the test and outcome variables in the following hypothesis. If soil temperatures rise, then plant growth will increase.
Test-soil temperatures Outcome-plant growth.
500
During which step is research conducted?
Collect Information
500
What is the difference between precision and accuracy?
Precision means being close to the achieved results. Could be far from the intended results. Accuracy is being close to the intended results for the investigation.

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 the muscles in the body require more oxygen to work.

Test- practice shooting free throws Outcome- making baskets
