What is a CER? A Claim, Evidence, and Reasoning (or CER) is a scientific explanation. It is a way that we explain our evidence-based claims. It has 3 parts:

Conclusions Based on Data

Claim  A statement about the solution to the problem  A statement that answers a question

Evidence  scientific data that supports the claim  data can be  quantitative – the actual numbers (measurements) with appropriate units  qualitative - observations using the five senses

Reasoning An explanation…  shows why the data counts as evidence to support the claim  includes scientific principles or background knowledge of the topic  expresses why the experiment had these results using scientific terminology

Practice On your paper, write a statement explaining whether or not any of the liquids are the same substance. Use the format of conclusions based on data in your explanation.

A Simple CER Claim—Liquids 1 and 4 are the same liquid. Evidence—Liquids 1 and 4 have a density of 0.98 g/mL, a melting point of -98°C, and both have no color. Reasoning—These physical properties are unique to a particular substance. Since the density and melting point of these two liquids are exactly the same, the liquids must be the same.

Reasoning—These physical properties are unique to a particular substance. Since the density and melting point of these two liquids are exactly the same, the liquids must be the same. Answer the question, “Are any substances the same?”

Reasoning—These physical properties are unique to a particular substance. Since the density and melting point of these two liquids are exactly the same, the liquids must be the same. Uses all data from the given table with appropriate units.

Key terminology used to explain WHY evidence supports claim.
