1. Conclusions Based on Data

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

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

4. 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

5. 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.

6. 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.

7. 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. Answer the question, “Are any substances the same?”
