Scientific Method
What is the first step in the scientific method?
What is Observation.
What can be used to gather initial observations?
What is your five senses
What step of the scientific method do you predict a possible answer to a problem or a question?
What is Hypothesis.
(Remember it must include the dependent and independent variable)
What are the two types of variables stated in a good hypothesis?
What is Independent and Dependent variables
Describe the difference between the control group and a constant.
What is used for comparison (control) and held the same (constants)
What step of the scientific method do you test your hypothesis?
What is Experiment.
This type of observation is measurable.
What is Quantitative Measurement.
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. It should be a testable statement.
What is the responding variable or factor that may or may not change due to manipulation?
What is Dependent Variable.
(DRY)
What components make a good graph?
What is title, labeling x and y axis, and equal increments on number lines
What step in the scientific method do you make careful observations and write down quantitative and qualitative observations?
What is Collect and Record data
This type of observation is describable.
What is Qualitative Measurement.
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. (Increasing the amount of milk you drink 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.
(MIX)
The ________________ involves a series of steps that are used to investigate a natural occurrence.
What is Scientific Method.
In which step of the scientific method do you review results, state if hypothesis is supported or rejected, and make connections to research?
What is Conclusion
Blue, rough, metal are all examples of what type of observation?
What is Qualitative Measurement.
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 lung cancer.
In an experiment what are held constant so that they do not influence the experimental outcome called?
What are constants
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.
List all eight steps of the scientific method.
What is Observation, Question, Research, Hypothesis, Experiment, Collect and Record Data, Analyze Results, Conclusion.
Peer review follows.
The tree has grown 25cm and has 5 new leaves are 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.
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 some constants be in this experiment?
What is... using the same potting soil, making sure both plants have an equal amount of light, water,... etc.
