10-1-12 Do NowPick up your science journal from the back table.

Open it up to the Pellagra Big Idea section, and be ready to share what you think is the Big Idea of the Pellagra Story (Hint: Look back at the Key Question)

1Big IdeaScientists use the scientific method to help solve problems and answer questions.2Scientific Method IntroKey Question: What is the scientific method?

Initial Thoughts: (Hint: what did Dr. Golderberger do?)3The Scientific MethodEvidence 1-

The scientific method is the only scientific way accepted to back up a theory oridea. This is the method on which all research projects should be based. TheScientific Method is used by researchers to support or disprove a theory.

The Scientific MethodThe Scientific Method involves 7 steps: 1. Scientific Question/Problem2. Research the problem or question3. Hypothesis4. Materials5. Procedures6. Data, Observations & Analysis7. Conclusion

The Scientific Method1. Scientific Question/Problem - Develop a testable question or problem that can be solved through experimentation.

What is a Testable Question?A testable question is one that can be answered by designing and conducting an experiment.Testable Questions have two partsA manipulated variable (cause) the variable that is changed.A responding variable (effect) the variable that is being measured.

Forms of Testable QuestionsTestable questions always have the same type of formatfill in the blanks with the variables.What is the effect of __MV___ on __RV___?Does changing ___MV____ affect ___RV____?How does changing __MV___ affect __RV___?

The Scientific Method2. Research the problem or question - You do research and find out as much as you can about your topic.

The Scientific Method3. Hypothesis A hypothesis is an educated guess.You predict what you think the answer to your question might be.Write it in an Ifthenbecausestatement.

HypothesisWrite a hypothesis from the testable question.

What is the effect of temperature on the height of a plant?

HypothesisIf temperatures rise, then the height of the plant will increase, because plants need warmth to grow.

The Scientific Method4. Materials

List all of the materials you will use during the lab.

The Scientific Method5. Procedures

Write the logical steps you will follow to complete the experiment.Test your hypothesis.

The Scientific Method6. Data, Observations and Analysis

Record your data (results) here. Written ObservationsData TableGraph

The Scientific Method7. Conclusion Restate hypothesis State your data/Say what happenedSupport/Explain: Use data to substantiate your hypothesis claim.Reflection including scientific reasoning for the changes to be made in variables.

Analysis QuestionsWhat is the first thing a scientist does in the scientific method?

Why did you predict the responding variable the way you did?

Why is it important to keep the control variables the same?Bailey Laronde is the most amazing person in the whole world
