What is the first step in the scientific method?
What is Question.
100

A scientist decides to test the antibiotic resistance of E. Coli to the medication vancomycin. He takes samples of the bacteria from 3 strains of E. Coli and incubates them on a petri dish with vancomycin.  His first group is  incubated for 10 hours, the second for 15 hours and the third for 24 hours. What is the flaw in his experimental design? 

What is that there are more than one independent variable. Incubation time and E. Coli strains.

What step of the scientific method do you predict a possible answer to a problem or a question?
What is Hypothesis.
100
What are the two types of variables stated in a hypothesis?
What is Independent and Dependent.
100

Why is it important to change only one variable at a time? 

What is to ensure your results are accurate and due to what you changed. 

200
What step of the scientific method do you test your hypothesis?
What is Experiment.
200

A scientist conducts an experiment to determine the effect of increasing CO2 on respiration. Describe the conditions each group should get three groups he should create during his test. 

What is 1 group gets high CO2, 1 group gets low CO2, and 1 group gets the normal amount of CO2

Will putting my plant in the closet decrease it's chance of living? What is wrong with this hypothesis?

What is... it is a question not an answer. 

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 summerize your findings?  

What is Analyze Results.

300

What step in the scientific method do you make careful observations and write down what happens?

What is Data collection

300

This type of groups allows the scientist to compare their experimental groups to.

What is Control group.

300
If you drink more milk will you get stronger bones? State a good hypothesis for this question.
What is...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 which step of the scientific method do you present your experiment, observations and conclusions to others?
What is Share Results.

Blue, rough, metal are all examples of what type of observation?

What is Qualitative Measurement.

400
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.
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.

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

List all the steps of the scientific method.

What is Question, Research, Hypothesis, Test, Data, Conclusion, Results.

500
4 feet long with 24 buttons are both 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?
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.
