Give your chemistry students a focused look at reaction and mixture decision with ninety questions built for real classroom use, whether you are starting a new unit or reviewing before a test.
Sample questions include "What distinguishes a chemical reaction from a mixture?", "Which of the following best represents a chemical change?", and "Which statement about mixtures is true?"
Each worksheet reviews the same core ideas from a different angle. Use them across a week or unit so students see the material three times without it ever feeling repetitive.
This set is part of a complete NGSS aligned chemistry unit. The unit also covers Reaction Signs Checklist, Color Change Comparison, Temperature Shift Report, Gas Production Observation, Precipitate Formation Note, and Solubility Change Summary, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 6-8 chemistry classes, and for NGSS aligned review at any point in the school year. This set is aligned to NGSS standard MS-PS1-2.
