2 What is the Scientific Method? A process used to investigate a questionThere are many different versions of the scientific method. This is our version.There are seven steps!
3 7 steps Question Research Hypothesis Materials Procedure Results Conclusion
4 Question- Step 1Looking for a piece of information that you don’t know.It is best expressed as an “open-ended question”, which is a question answered with a sentence, not just a yes or no answerShould be simple, direct, and measurableEx. How does the tread of the shoe affect the amount of friction?What is wrong with this example - Is a flip flop better than a sandal ?
5 Question Practice Write two questions you can test on plant growth ________________________________________________________________
6 Hypothesis- Step 3A hypothesis is an educated guess developed using background knowledge that can be testedBased on the information found in researchEasy format: “If …..then, becauseAll hypothesis have support.
7 Hypothesis PracticePractice writing hypotheses for your two plant growth questions.Ex.1_____________________________________________________________Ex.2_____________________________________________________________
8 Research- Step 2Looking for the information that would help to answer the questionCould be books, journals, magazines, internet, labels, or an expert.Practice- If you are doing an experiment on plant growth, what do you need to know about plants? Where could you get the information?
9 Experiment (broken into 3 parts) Materials- Step 4 Provides a list of all things used in the experimentShould be specific, including measurementsPractice- List the materials you would need to do an experiment on how light affects plant growth.
10 Procedure- Step 5Step-by-step instructions on how to do the experimentAnother person should be able to do your experiment based on your steps.Should produce measurable results
11 Procedure PracticeExplain what needs to be changed to make the steps clearer.Put some soil in each cup.Put the plants in different places so each plant gets different amounts of light.Water the plants every two days.
12 Results- Step 6 The data collected in the experiment. Include a data table, this is where you record your results.You might need to include a chart or a graphSimple paragraph to state what happened
13 Results PracticeWhat information would you graph if you did the experiment about how the amount of light affects plant growth?
14 Conclusion- Step 7 Answers the question States if the hypothesis was correct or incorrectDiscusses experimental errorCould you be wrong? Could the experiment have given the wrong results?
