Science
Science is asking questions and performing tests to try to answer those questionsIf it cannot be answered it’s NOT science
Questions:
What is science and what is not?
SC.912.N.2.3: What is science and what is notSC.912.N.2.2: What types of questions are outside science.

Pseudoscience - fields of study may seem like science because they use scientific informationExamples: Astrology and
phrenology
Questions:
What is psuedo- science?
Why can some fields seem like science?
SC.912.N.2.3 What is the difference between science and pseudoscience
![Page 4: Introduction To Science](https://reader035.vdocument.in/reader035/viewer/2022081603/5681431a550346895daf7581/html5/thumbnails/4.jpg)
Science involves many skills likeObservingComparing CommunicatingRelating Applying
It is NEVER about guessing or manipulating data
It is ALWAYS changing because of discoveries
Questions:
What type of skills are involved with science?
Why does science change?
SC.912.2.3 What is science
![Page 5: Introduction To Science](https://reader035.vdocument.in/reader035/viewer/2022081603/5681431a550346895daf7581/html5/thumbnails/5.jpg)
Many discoveries contribute to society:In health fieldsOther fields
All information about the discoveries needs to be given to the public so they can make good choices
Questions:
How does science contribute to society?
Give an example of why society needs all info?

Summary Section
What 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?

Scientific Method
Scientists believe that the universe is based on rules
These rules can be discovered with systematic studyScientific method
Questions:
Why is it important to use systematic studies
![Page 8: Introduction To Science](https://reader035.vdocument.in/reader035/viewer/2022081603/5681431a550346895daf7581/html5/thumbnails/8.jpg)
Steps includeMake observation Ask a question Do research Form a hypothesis Test hypothesis Analyze data and draw conclusions
• Before publishing – it goes to a peer review
Questions:
What are the steps of the scientific method?
What must be considered at each step? SC.912.N.1.1 Be able to use the scientific method
SC.912.N.1.4 Identify reliable resourcesSC.912.N.1.6 How are inferences made from observation
![Page 9: Introduction To Science](https://reader035.vdocument.in/reader035/viewer/2022081603/5681431a550346895daf7581/html5/thumbnails/9.jpg)
When Doing Experiments
Many methods of test a question Parts:
• Independent variable• Dependent variable • Control• Constants
Use quantitative not qualitative data
Questions:What are the
IV, DV, constants and controls and why are they important to determine before starting?
SC.912.N.1.1 Use scientific method
![Page 10: Introduction To Science](https://reader035.vdocument.in/reader035/viewer/2022081603/5681431a550346895daf7581/html5/thumbnails/10.jpg)
Models might be used Data must be consistent,
accurate, precise, and detailed Organize data – in graphs and
charts Make detailed observations not
inferences Draw conclusions using data
(inferences are drawn at this point)
Questions:
What are some skills that must be included in an experiment and why?
LA.910.4.2.2 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

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?

Taking Measurements
Use the metric system MUST
It is universal and based on multiples of 10
Questions:
Why is the metric system used?
SC.912.N.1.1 Use the scientific methodLA.910.4.2 Record info accurately and coherently
![Page 14: Introduction To Science](https://reader035.vdocument.in/reader035/viewer/2022081603/5681431a550346895daf7581/html5/thumbnails/14.jpg)
The Metric System
The basic units used in science include:Meters – lengthGrams – massLiters – volumeCelsius - temperature
Use the most appropriate unitKilo Hecto Deka Base Deci Centi Mill
Questions:
What are the base unit for each type of measure-ment?
When are each unit used?
SC.912.N.1.1 Use the scientific methodMA.912.S.1.2 Use appropriate constant measurements
![Page 15: Introduction To Science](https://reader035.vdocument.in/reader035/viewer/2022081603/5681431a550346895daf7581/html5/thumbnails/15.jpg)

Use The Proper Graphs
Line graphs Bar graphs Circle graphs
Questions:
What are the different types of graphs and when are each used?
SC.912.N.1.1 Use scientific methodLA.910.2.2.3 Organize to show relationships of facts and ideasMA.912.S.3.2 Collect, organize and analyze data

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?

Theories
A theory might be generated if there are enough tests to explain an observationIt can be revised or replaced They will NEVER become laws
Questions:
What is a theory?
When can it be revised or replaced?
SC.912.N.3.1 Theory is a culmination of many investigations and based on current knowledgeSC.912.N.3.4 Theories cannot become lawsSC.912.N.1.5 Example of how similar investigations from different places and backgrounds result in the same resultsSC.912.N.1.3 The strength of claims depend on thinking and keeping in mind different views
![Page 22: Introduction To Science](https://reader035.vdocument.in/reader035/viewer/2022081603/5681431a550346895daf7581/html5/thumbnails/22.jpg)
Laws
These state a repeated observation about nature with NO explanations
They are based on a consensus of scientists that agree on the stated observations
Laws will NEVER become theories
Questions:
What is a law?
When can it be revised or replaced?
Why can’t a theory become a law and vise versa?
SC.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 from different places and backgrounds result in the same resultsSC.912.N.1.3 The strength of claims depend on thinking and keeping in mind different views
![Page 23: Introduction To Science](https://reader035.vdocument.in/reader035/viewer/2022081603/5681431a550346895daf7581/html5/thumbnails/23.jpg)
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.
