a series of steps that scientists use to answer questions and solve problems

problem

always in form of a question; the question we are trying to answer by doing the experiment

hypothesis

An educated guess

data and results

A summary of the data you have collected (graphs, tables, charts, photos, etc.); all your observations from the experiment

conclusion

the answer to your question; a summary of what you have learned from an experiment

control group

part of an experiment that does not contain a variable; all conditions are kept normal; used as a COMPARISON

independent/manipulated variable

factor in an experiment that a scientist purposely changes; the cause

dependent/responding variable

the factor that is measured; the result/effect of the experiment

Problem

The question you want to answer. Inquiry has led to many discoveries in science. Ask your question.

Hypothesis

Tell what you think is the answer to the problem

Hypothesis

Should be written as an "if...then" or an "I think that..." statement

Experiments

Test your hypothesis. You may need to do this step more than once to see if the results are the same each time.

Data

Organize into charts, tables, drawing, and diagrams. You can decide what the information means.

Conclusion

Compare your results and hypothesis. Decide if your hypothesis is right or wrong. Tell what you decide.

Procedure

The step by step directions to follow in the experiment

Materials

The tools needed in an experiment

Observations

You use the 5 senses to gather information

Hypothesis

Prediction; can be wrong
