What is Science?•Science is the attempt to
put the universe in some kind of order that humans can understand.
•From Latin scire (which means “to know”)

What do I need to know about the nature
of science?

Science is constantly changing!

Science is constantly changing!
• Scientists verify each other’s work.
• Every once in a while, the scientists find that a theory or scenario does not always hold true…. So what then?????
![Page 6: Science & the Scientific Method](https://reader035.vdocuments.mx/reader035/viewer/2022062422/568138ff550346895da0b49f/html5/thumbnails/6.jpg)
SCIENCE MUST CHANGE TO FIT THE NEW FINDINGS.
This is why Science is constantly changing.

What’s the point????
![Page 12: Science & the Scientific Method](https://reader035.vdocuments.mx/reader035/viewer/2022062422/568138ff550346895da0b49f/html5/thumbnails/12.jpg)
Scientists can be of any age, race,
gender, religion or culture!
![Page 13: Science & the Scientific Method](https://reader035.vdocuments.mx/reader035/viewer/2022062422/568138ff550346895da0b49f/html5/thumbnails/13.jpg)
You can be a Scientist!
![Page 14: Science & the Scientific Method](https://reader035.vdocuments.mx/reader035/viewer/2022062422/568138ff550346895da0b49f/html5/thumbnails/14.jpg)
And…..Scientists rarely work alone...
They are much happier working in groups!
![Page 15: Science & the Scientific Method](https://reader035.vdocuments.mx/reader035/viewer/2022062422/568138ff550346895da0b49f/html5/thumbnails/15.jpg)
So far we know…•Science is constantly changing•Scientists can be from any race,
gender, age, culture or religion.•Scientists like to work in groups!

So, How Do We Study Science?
![Page 17: Science & the Scientific Method](https://reader035.vdocuments.mx/reader035/viewer/2022062422/568138ff550346895da0b49f/html5/thumbnails/17.jpg)
We use the Scientific Method!!!
![Page 18: Science & the Scientific Method](https://reader035.vdocuments.mx/reader035/viewer/2022062422/568138ff550346895da0b49f/html5/thumbnails/18.jpg)
Step 1: Identify a problem
•Ask a question.
![Page 19: Science & the Scientific Method](https://reader035.vdocuments.mx/reader035/viewer/2022062422/568138ff550346895da0b49f/html5/thumbnails/19.jpg)
Step 2: Research the Problem
• Look at reliable sources• Determine what is already
known about the problem.• Write this under “Background
Information” in the lab write-up.
![Page 20: Science & the Scientific Method](https://reader035.vdocuments.mx/reader035/viewer/2022062422/568138ff550346895da0b49f/html5/thumbnails/20.jpg)
Step 3: Form a Hypothesis
•Hypothesis- a testable explanation of an observation
• A hypothesis is NOT just an educated guess about what you think will happen. It must be TESTABLE!!!!
![Page 21: Science & the Scientific Method](https://reader035.vdocuments.mx/reader035/viewer/2022062422/568138ff550346895da0b49f/html5/thumbnails/21.jpg)
Step 4: Design an Experiment
•How are you going to test your hypothesis?
•You Design an Experiment!
![Page 22: Science & the Scientific Method](https://reader035.vdocuments.mx/reader035/viewer/2022062422/568138ff550346895da0b49f/html5/thumbnails/22.jpg)
Step 5: Test your hypothesis
•Follow a procedure•Keep the procedure the same every time!
![Page 23: Science & the Scientific Method](https://reader035.vdocuments.mx/reader035/viewer/2022062422/568138ff550346895da0b49f/html5/thumbnails/23.jpg)
How many times should you repeat the trials to
make sure your experiment is valid?
![Page 24: Science & the Scientific Method](https://reader035.vdocuments.mx/reader035/viewer/2022062422/568138ff550346895da0b49f/html5/thumbnails/24.jpg)

Step 6: Organize your data
• Put your data into a data table
IndependentVariable
__________(unit)
Levels
Dependent Variable _______________ (unit)
Trial 1 Trail 2 Trail 3 mean range
![Page 26: Science & the Scientific Method](https://reader035.vdocuments.mx/reader035/viewer/2022062422/568138ff550346895da0b49f/html5/thumbnails/26.jpg)
Step 6: Organize your data
•Make the data table into a graph
•Graphs make it easier to see patterns in the data.
![Page 27: Science & the Scientific Method](https://reader035.vdocuments.mx/reader035/viewer/2022062422/568138ff550346895da0b49f/html5/thumbnails/27.jpg)
Step 6: Organize your data
• DRY MIX– Dependent Variable = Responding Variable = Y axis– Manipulated Variable = Independent Variable = X axis
![Page 28: Science & the Scientific Method](https://reader035.vdocuments.mx/reader035/viewer/2022062422/568138ff550346895da0b49f/html5/thumbnails/28.jpg)
Step 7: Draw Conclusion(s)
•Was your hypothesis correct?• If your hypothesis was not
accurate or if you think there was an error collecting data Start over and re-do experiment!

Step 8: Communicate Results
•Tell the scientific community what you discovered!
