Students read 4 short and engaging informational text passages about physical changes and chemical reactions. Then, they complete a CER for each section using evidence from the text for each one.
The CERs focus on evidence of a physical versus a chemical change. Concepts included include physical and chemical changes to matter and the terms exergonic and endothermic.
Each of the 4 Sections (1 page each) Include:
- Short, engaging text passage
- Claims-Evidence-Reasoning question(s)
- Follow up questions
Passage Topics Include:
- Glow sticks
- Popcorn
- Bioluminescence in the ocean
- Cold packs (for injuries)
We find this a helpful practice for standardized tests because it requires using background knowledge and information from text to arrive at an answer.

Related Standards:
- NGSS MS-PS1-2: Analyze and interpret data on the properties of substances before and after interaction to determine if a chemical reaction occurred.
- NGSS MS-PS1-5: Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.
