Help your students build real understanding of diffusion and particle evidence through ninety questions that move from basic recognition to genuine reasoning about physics concepts.
Students will answer questions such as "In which state of matter does diffusion occur most rapidly?", "Which of the following best explains diffusion in terms of particle theory?", and "How does concentration gradient influence diffusion?"
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 Atomic Theory Overview, States of Matter and Particle, Temperature and Particle Speed, Modeling Gases and Pressure, Particle Diagrams and Models, and Conservation in Phase Changes, 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-PS1-1.
