What are the steps of the scientific method?
• There are many different processes that scientists use. There isn’t just ONE correct way to do the scientific method. The steps we will learn are a pattern that scientists tend to use, but they are not the only way to do science.

Scientific method– Observing– Questioning– Identifying a
problem

Scientific method
– Researching
![Page 5: Scientific methods. What are the steps of the scientific method? There are many different processes that scientists use. There isn’t just ONE correct.](https://reader035.fdocuments.us/reader035/viewer/2022070415/5697c0301a28abf838cdaf23/html5/thumbnails/5.jpg)
Scientific method
– Forming a hypothesis
![Page 6: Scientific methods. What are the steps of the scientific method? There are many different processes that scientists use. There isn’t just ONE correct.](https://reader035.fdocuments.us/reader035/viewer/2022070415/5697c0301a28abf838cdaf23/html5/thumbnails/6.jpg)
Scientific method – form a hypothesis
• What is a hypothesis?– Opinion (tentative)– Hypothesis– Theory– Law– Fact
![Page 7: Scientific methods. What are the steps of the scientific method? There are many different processes that scientists use. There isn’t just ONE correct.](https://reader035.fdocuments.us/reader035/viewer/2022070415/5697c0301a28abf838cdaf23/html5/thumbnails/7.jpg)
Scientific method
– experimenting
![Page 8: Scientific methods. What are the steps of the scientific method? There are many different processes that scientists use. There isn’t just ONE correct.](https://reader035.fdocuments.us/reader035/viewer/2022070415/5697c0301a28abf838cdaf23/html5/thumbnails/8.jpg)
Scientific method - Experiment
• A Variable is something that could change in your experiment.
![Page 9: Scientific methods. What are the steps of the scientific method? There are many different processes that scientists use. There isn’t just ONE correct.](https://reader035.fdocuments.us/reader035/viewer/2022070415/5697c0301a28abf838cdaf23/html5/thumbnails/9.jpg)
Scientific method - Experiment
• The Independent variable is the factor in the experiment that is changed on purpose.
• The independent variable can also be called the manipulated variable.
• A Controlled experiment only has one independent variable.

Scientific method - Experiment
• The dependent variable is that factor that responds to the change you made in the independent variable. (It’s the thing that changes when you changed something else.)
• The dependent variable is also called a responding variable.

Scientific method - Experiment
• Controlled Variables are characteristics that are kept the same in all trials. (Things that could change, but you make sure they don’t.)
• Controlled variables are also called Constants.

Scientific Method
• Modeling

Scientific method
– Collecting and analyzing data
![Page 14: Scientific methods. What are the steps of the scientific method? There are many different processes that scientists use. There isn’t just ONE correct.](https://reader035.fdocuments.us/reader035/viewer/2022070415/5697c0301a28abf838cdaf23/html5/thumbnails/14.jpg)
Scientific method
– Forming conclusions• (Was your hypothesis
correct?)

“Understanding is always a journey, never
a destination.Knowledge begets
questions, which beget new technology, which
provides answers-which in turn beget questions. This is the implacable carousel of research.”
- Richard Fortey
