Scientific Method Lab 2

observation

step one, information obtained through the senses, qualitative data

question

step two, observation turned into a question

hypothesis

step three, tentative answer to the question, based on reasoning

prediction

step four, assume the hypothesis is correct and make a prediction about the outcome of a test, usually in the form of "if...then" statement

experiment

step five, test the prediction, must be repeatable, increase sample size, multiple trials, accurate description of materials used including quantities

conclusion

step six, use results to evaluate hypothesis, accept or reject hypothesis, may lead to further questions and experimentation

independent variable

treatment or condition that is manipulated by the experimenter (if prediction)

dependent variable

event that is measured or observed (then prediction)

control variable

all factors that are kept the same (constant)

experimental group

treated with the independent variable

control group

not treated with the independent variable
