Help your students build real understanding of surface area and reaction speed through ninety questions that move from basic recognition to genuine reasoning about physics concepts.
The set includes questions like "What is the relationship between surface area and the rate of reaction in solids?", "If two solids react with a liquid, how can their reaction rates be compared?", and "What is the primary effect of surface area on the rate of a solid reacting with a liquid?"
All three worksheets cover the same topic in different question styles. That means you can use one as a pretest, another for practice or homework, and the third as a follow up quiz, without students ever seeing the same question twice.
This set is part of a NGSS aligned physics unit. The unit also covers Intro to Reaction Rates, Temperature_s Effect on Rate, Concentration and Rate, Catalysts in Action, Graphing Rate Data, and Particle Collision Theory, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 6-8 physics classes, and for review at any point in the school year. This set is aligned to NGSS standard MS-PS1-5.
