Scientific Explanations
Scientific explanation are different from everyday explanations because they are based on evidence. Science students need to explain conclusions that they reach, from taking data, in a clear way. Claim, Evidence and Reasoning is a format that makes writing very complex ideas, a little easier. When you are writing a paper, answering questions on a quiz or CSAP, you have a much greater chance of proving what you know if you use the CER format.
Claim:
This is the idea that you are trying to prove. In English class, you would call it a thesis statement. It could also be the introductory paragraph in a paper.This is your conclusion statement that answers the problem question of an experiment. It is a FINAL hypothesis based on evidence and scientific reasoning.
Evidence:
This section will be very dry. You should describe graphs and outline evidence. Your own thoughts will go in the reasoning section. Evidence should include:- Studies that support your claim
- Data
- Analysis
- Facts
Reasoning:
This is where you will put your ideas about what the evidence means. Reasoning explains why evidence came out the in the way that it did. Reasoning should include:- Your ideas on why graphs have a particular shape.
- Your ideas on why your claim is true.
- You should reach logical conclusions based on evidence.
- Build your argument to prove your point.
