Collection of knowledge based on the observation and experimentation of the natural world.
What is science?
100
The step of the scientific method where you predict a possible answer to a problem or a question. It is a statement not a question.
What is Hypothesis?
100
The two types of variables stated in a hypothesis?
What is Independent (manipulated) and Dependent (responding)?
100
Which step of the scientific method is missing:
Question
Formulate a Hypothesis
______________
Results
Conclusion
What is Experiment.
200
What step of the scientific method do you test your hypothesis?
What is Experiment.
200
This type of observation is measurable (deals with numbers)
What is Quantitative Measurement?
200
Make the following question more "testable":
How will sunlight effect my plant?
Various answers. Example of a more testable one: Will placing my fern inside of my closet for a week cause it to wither and die?
200
What is the responding variable or factor that may or may not change due to manipulation?
What is Dependent Variable.
200
In which step of the scientific method do you use your information to draw conclusions about your experiment?
What is Results?
300
The step where you write down exactly how you do the experiment and what you used to do your experiment.
What is materials and method? or What is procedures and materials?
300
This type of observation is descriptive.
What is Qualitative Measurement?
300
If you drink more milk will you get stronger bones?
State a good hypothesis for this broad, nearly testable question.
Various answers. Example would be: If you increase the amount of milk you drink, then you will increase the strength of your bones.
300
What is the term we use to describe the manipulated variable or factor that the experimenter intentionally changes?
What is Independent Variable.
300
The ________________ involves a series of steps that are used to investigate a natural occurrence.
What is Scientific Method?
400
In this step of the scientific method you reflect on the results, see if the hypothesis is correct or not.
What is conclusion?
400
This is the study of life.
What is biology?

If high school seniors smoke regular cigarettes, will they have a better chance of getting lung cancer when they are in their 40's or 50's?
State a good hypothesis for this question.
Various answers. Example: If high school seniors increase the number of traditional cigarettes they smoke, then they will increase their chance of getting lung cancer in their 40's or 50's.
400
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 Control?
400
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.
500
All six steps of the scientific method in logical order.
What is Observe, Question, Hypothesis, Experiment, Results, Conclusion? And also after this we share our findings.
500
To make a prediction based on prior knowledge of something that you observe.
What is inference?
500
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.
500
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.
500
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.
