LOGICAL EXPLANATION

LAW

IF A THEORY IS TESTED OVER AND OVER AND DOES NOT CHANGE IT IS A LAW

RESEARCHHYPOTHESISEXPERIMENTANALYSISCONCLUSION

STATE THE PROBLEM

RESEARCH

FIND OUT MORE FACTS

HYPOYHESIS

EDUCATED GUESS BASED ON FACTS

THIS IS NOT.. BUBBA I KNOW THIS..

EXPERIMENT

MUST FIND EVIDENCE TO SUPPORT HYPOTHESIS

ANALYSIS

LOOK AT DATA YOU HAVE GATHERED

CHARTS

GRAPHS

CONCLUSION

HOW ARE THE RESULTS SIMILAR OR DIFFERENT FROM HYPOTHESIS

WHAT DO YOU DO NOW?
