HS-PS1-5: Collision Theory and Rates of Reaction
Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs. (Patterns)
Clarification Statement: Emphasis is on student reasoning that focuses on the number and energy of collisions between molecules.
Assessment Boundary: Assessment is limited to simple reactions in which there are only two reactants; evidence from temperature, concentration, and rate data; and qualitative relationships between rate and temperature.
The following assessments were created by science teachers hoping to better understand the NGSS. In most cases teachers went from standard to assessment in around an hour. These are drafts and should be used accordingly. Feel free to improve these assessments or contribute to the collection. Learn more about assessment design here.
