Scientific Inquiry Process Scientists use many ways to study the
natural world and propose explanations based on the evidence they gather.
Pose a question? (use observations and research to find a question you want to know the answer to)

What is a good question? Avoid Why? Questions Is the question testable? Don’t ask opinions!!!!!!!
What can you measure to find the answer? Do Research on the topic!!!!!!!!!!!!!!!!

Observing Using senses to gather information
Quantitative- observations with numbers (amounts)
Qualitative- observations with descriptions

Inferring When you interpret or explain
observations you made
![Page 8: What is Science? Observing Inferring Predicting Testing.](https://reader036.fdocuments.in/reader036/viewer/2022062518/56649ea25503460f94ba653a/html5/thumbnails/8.jpg)
Predicting Forecasting what you think will happen
based on observations, experiences, and evidence
![Page 9: What is Science? Observing Inferring Predicting Testing.](https://reader036.fdocuments.in/reader036/viewer/2022062518/56649ea25503460f94ba653a/html5/thumbnails/9.jpg)
Hypothesis Form a statement that is an explanation
to the question you want to answer.
It must be testable, to see if it is true!
Ex: If food is restricted from dogs, then they become more food aggressive.

Experiment Design an experiment to test your
hypothesis.
Every experiment needs parts that are controlled and parts or a part that varies or changes. These are called variables.
Independent, Dependent, and Controlled variables
![Page 11: What is Science? Observing Inferring Predicting Testing.](https://reader036.fdocuments.in/reader036/viewer/2022062518/56649ea25503460f94ba653a/html5/thumbnails/11.jpg)
Variables Independent Variables- (manipulated) parts
of the experiment that are being tested, you are setting them up within the experiment to have a comparison.
Dependent Variables- (responding) the part of the experiment that varies depending on what happens within the experiment. The variable that is measured for results.
![Page 12: What is Science? Observing Inferring Predicting Testing.](https://reader036.fdocuments.in/reader036/viewer/2022062518/56649ea25503460f94ba653a/html5/thumbnails/12.jpg)
Variables Controlled variables or constants- things
that are not changed within the experiment on purpose.
Need to control everything except what is being tested (the independent and dependent variables).
Ex: environment and conditions

Collecting Data Observe and collect measurements
during the experiment
Organize Data into charts
Express your findings in Graphs (Circle, Bar, and Line Graphs)

Graphs Circle (Pie) Graph- Always shows parts
of a whole = 100% (Always in %)
Line Graph- Shows 2 variables usually something over a period of time
Bar Graph- Shows multiple variables or groups to compare

Draw a Conclusion Summarize what you find
Reject or Support your Hypothesis
Communicate what you find Ex: publish articles
