2 Science If it cannot be answered it’s NOT science Questions:What is science and what is not?Science is asking questions and performing tests to try to answer those questionsIf it cannot be answered it’s NOT scienceSC.912.N.2.3: What is science and what is notSC.912.N.2.2: What types of questions are outside science.
3 Questions:What is psuedo- science?Why can some fields seem like science?Pseudoscience - fields of study may seem like science because they use scientific informationExamples: Astrology and phrenologySC.912.N.2.3 What is the difference between scienceand pseudoscience
4 Science involves many skills like ObservingComparingCommunicatingRelatingApplyingIt is NEVER about guessing or manipulating dataIt is ALWAYS changing because of discoveriesQuestions:What type of skills are involved with science?Why does science change?SC What is science
5 Many discoveries contribute to society: Questions:How does science contribute to society?Give an example of why society needs all info?Many discoveries contribute to society:In health fieldsOther fieldsAll information about the discoveries needs to be given to the public so they can make good choices
6 Summary SectionWhat are two examples of questions that are outside of science but may seem like science?Explain why some fields seem like science – use an example to explain your answer?What is never done in science?Why does science always change?Give an example of why people need all information about a discovery?
7 Scientific MethodQuestions:Why is it important to use systematic studiesScientists believe that the universe is based on rulesThese rules can be discovered with systematic studyScientific method
8 What are the steps of the scientific method? Questions:What are the steps of the scientific method?What must be considered at each step?Steps includeMake observationAsk a questionDo researchForm a hypothesisTest hypothesisAnalyze data and draw conclusionsBefore publishing – it goes to a peer reviewSC.912.N.1.1 Be able to use the scientific methodSC.912.N.1.4 Identify reliable resourcesSC.912.N.1.6 How are inferences made from observation
9 When Doing Experiments Questions:What are the IV, DV, constants and controls and why are they important to determine before starting?Many methods of test a questionParts:Independent variableDependent variableControlConstantsUse quantitative not qualitative dataSC.912.N.1.1 Use scientific method
10 What are some skills that must be included in an experiment and why? Questions:What are some skills that must be included in an experiment and why?Models might be usedData must be consistent, accurate, precise, and detailedOrganize data – in graphs and chartsMake detailed observations not inferencesDraw conclusions using data (inferences are drawn at this point)LA Record info and ideas accurately and coherently noting reliable resourcesSC.912.N.1.1 Use the scientific methodSC.N.1.6 How are inferences made from observations
12 Summary Section Why do scientists use the scientific method? What are the steps of the scientific method?Why must your resources be reliable and give an example of a good resource?What is the difference between a dependent and independent variable?Why are models used?What does it mean when they say inferences are made from observations?
13 Taking Measurements Use the metric system MUST Questions:Why is the metric system used?Use the metric system MUSTIt is universal and based on multiples of 10SC.912.N.1.1 Use the scientific methodLA Record info accurately and coherently
14 The Metric System The basic units used in science include: Questions:What are the base unit for each type of measure-ment?When are each unit used?The basic units used in science include:Meters – lengthGrams – massLiters – volumeCelsius - temperatureUse the most appropriate unitKilo Hecto Deka Base Deci Centi MillSC.912.N.1.1 Use the scientific methodMA.912.S.1.2 Use appropriate constant measurements
16 Use The Proper Graphs Line graphs Bar graphs Circle graphs Questions: What are the different types of graphs and when are each used?Line graphsBar graphsCircle graphsSC.912.N.1.1 Use scientific methodLA Organize to show relationships of facts and ideasMA.912.S.3.2 Collect, organize and analyze data
20 Summary Section Why is the metric system used? What are the base units for each type of measurement?When is each unit in the metric system used?Why is it important to appropriately collect, organize, and analyze the data collected?
21 Theories Questions: What is a theory? When can it be revised or replaced?A theory might be generated if there are enough tests to explain an observationIt can be revised or replacedThey will NEVER become lawsSC.912.N.3.1 Theory is a culmination of many investigationsand based on current knowledgeSC.912.N.3.4 Theories cannot become lawsSC.912.N.1.5 Example of how similar investigations fromdifferent places and backgrounds result in the same resultsSC.912.N.1.3 The strength of claims depend on thinking andkeeping in mind different views
22 LawsQuestions:What is a law?When can it be revised or replaced?Why can’t a theory become a law and vise versa?These state a repeated observation about nature with NO explanationsThey are based on a consensus of scientists that agree on the stated observationsLaws will NEVER become theoriesSC.912.N.3.4 The difference between a theory and law andwhy can’t one change to the otherSC.912.N.1.5 Example of how similar investigations fromdifferent places and backgrounds result in the same resultsSC.912.N.1.3 The strength of claims depend on thinking andkeeping in mind different views
23 Summary Section What is the difference between a theory and a law? Why can’t a theory become a law and vise versa?Explain how similar investigations in other places can give the same results.Explain why the strength of a claim is based on thinking and incorporating other peoples views.
