This document outlines the scientific method process in 6 steps: 1) State the problem or question to be studied, 2) Gather information through research, 3) Form a hypothesis, 4) Perform an experiment to test the hypothesis, 5) Analyze the experimental data through charts and graphs, and 6) Draw conclusions on whether the hypothesis was confirmed or a new hypothesis needs to be formed.

1. CATALYST Do you think chimpanzees can learn American Sign Language? How about use a computer? Why or why not?
5. Six: State the Problem The scientist identifies the question or subject that he/she wishes to study
6. Great: Gather Information The scientist researches the subject that he/she is studying. Places to do research: library, internet, encyclopedia, television, etc.
7. Farmers: Form Hypothesis A hypothesis is the scientists educated guess or best guess about what will happen in the experiment. Usually has the words If... Then IF I eat too much, THEN I will get sick Inference a logical interpretation based on prior knowledge or experience (Ex. You see a window broken and a baseball on the floor next to the shattered glass. You can -infer- that a baseball broke your window)
8. Plant: Perform Experiment Scientists develop a way to test their hypothesis Independent Variable (manipulated) : part of the experiment that can be changed or controlled Dependent Variable (responding) : What is measured in the experiment Control what you keep the same. A good experiment only changes one thing!
9. All: Analyze Data Scientists compile data into charts and graphs This helps make sense of the information taken from the experiment Quantitative numbers Qualitative description X axis is the dependent variable Y-axis is the independent variable
10. Day: Draw Conclusions Scientist decides whether the original hypothesis was correct. If the answer is YES then you are done If the answer is NO then a new hypothesis is made and you repeat the experiment
