What is Science? Observing Inferring Predicting Testing
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
Predicting Forecasting what you think will happen based on observations, experiences, and evidence
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
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.
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
Pie Graph/ Circle Graph
Draw a Conclusion Summarize what you find Reject or Support your Hypothesis Communicate what you find Ex: publish articles
