Physics ideas click fastest with real practice. This set gives your Grade 6-8 class ninety questions on concentration and rate.
Among the ninety questions, students will see prompts such as "What is the effect of temperature on the rate of reaction according to collision theory?", "What effect does increasing the surface area of a solid reactant have on the reaction rate?", and "Which factor does NOT affect the rate of a chemical reaction?"
Because the three worksheets share the same content in three different formats, you can spread them across the week: one for diagnosis, one for practice, and one for assessment, without repeating a single question.
This set is part of a NGSS aligned physics unit. The unit also covers Intro to Reaction Rates, Temperature_s Effect on Rate, Surface Area and Reaction Speed, 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.
