Science
• Relies on logic & creativity• Body of knowledge & way of knowing about
the unusual happenings around us called phenomena
• uses the methods of scientific inquiry to explain how the world works

Scientific Inquiry
• Involves questioning, observing, inferring, experimenting, finding evidence, collecting and organizing data, drawing valid conclusions & peer review
• To infer means to make a conclusion based on an observation
• Technique used for this process is called the scientific method, which is made up of steps
![Page 4: Aim: How can we use scientific inquiry to explain how the world works? DO NOW: In your notebook, describe what scientific inquiry means to you](https://reader035.vdocuments.mx/reader035/viewer/2022081515/5a4d1b167f8b9ab059991b86/html5/thumbnails/4.jpg)
The Scientific Method
• State the problem (question)• Formulate a hypothesis (prediction, based on
research)• Test the hypothesis (controlled experiment)• Make observations (data)• Come to a conclusion (answer to the problem)• Repeat the experiment

Research Plan
• Needed if you want to do an experiment• Background information needs to come from
reliable sources: scientific journals, books etc.

Experimental Design
• Large sample size should be used • Experiment should be repeated many times to
get the same results• Experiment should have a control group, in
addition to an experimental group

Improper Scientific Procedures
• Small sample size• Experiment wasn’t controlled well• Fact & opinion intermingled• Not citing adequate evidence• Basing conclusions on faulty, incomplete or
misleading use of numbers• Conclusion doesn’t follow logically from
evidence

Facts, Theories & Laws
• Fact: knowledge based on an experiment & careful observations
• Theory: scientific explanation, of some aspect of the natural world, based on the scientific method
• Law: statement based on repeated experimental observations that describes some aspect of the universe
