Scientific Method
The first step in the scientific method
What is Observe and Question?
The two types of observations
What are Qualitative and Quantitative Measurements?
During this step of the scientific method you predict a possible answer to a problem or a question.
What is a Hypothesis?
The two types of variables stated in a hypothesis
What are the independent and dependent variables?
This step of the scientific method is missing: Make observations, Ask questions, Formulate a hypothesis, ______________, Gather data, Analyze your results, Share the results
What is Experiment?
In this step of the scientific method you test your hypothesis
What is Experiment?
This type of observation is measurable or countable.
What is a Quantitative Measurement?
"Putting my plant in the closet will decrease its chance of living." This is not a valid hypothesis for this reason.
What is... it is missing "If" and "Then"?
The responding variable or factor that may or may not change due to manipulation
What is Dependent Variable?
During this step of the scientific method you use your information to draw conclusions about your experiment
What is Analyze Results?
You make careful observations and write down what happens during an experiment
What is Observe and Record Data?
Will you get stronger bones if you drink more milk? Construct a testable hypothesis for this question.
What is...If you increase the amount of milk you drink, then you will increase the strength of your bones?
The term we use to describe the manipulated variable or factor that the experimenter intentionally changes
What is the Independent Variable?
The ________________ involves a series of steps that are used to investigate a natural occurrence.
What is Scientific Method?
In this step you may present your experiment or publish a paper with your observations and conclusions to others.
What is Share Results.
Blue, rough, metal are all examples of this type of measurement
What is a 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 getting lung cancer.
In an experiment, the variables that are held constant so that they do not influence the experimental outcome are called this.
What are Controls or controlled variables?
List the independent and dependent variables in the following hypothesis. If soil temperatures rise, then plant growth will increase.
Independent - soil temperature
Dependent - amount of plant growth.
The Scientific Method (all of it)
What is Observe and Question, Hypothesize, Experiment, Observe and Record, Analyze Results, Share Results?
You want to see if there is a connection between how long you run and how fast your heart beats. Identify a testable hypothesis.
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.
Independent - the amount of practice shooting free throws
Dependent - the chances of making a basket
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.?
