This resource turns diffusion in cells into a complete, ready to use review for Grade 7 biology, covering the same idea from three different angles.
The set includes questions like "Why can small nonpolar molecules diffuse more easily than large polar molecules?", "Which of the following best describes a semipermeable membrane?", and "Which molecule is least likely to diffuse directly through the lipid bilayer of a cell membrane?"
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 standards aligned biology unit. The unit also covers How Cell Theory Developed, Cell Theory as a Scientific, Identifying Major Cell Structures, Organelles and Cell Function, Structure and Function in Cells, and Comparing Plant and Animal Cells, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 7 biology classes, and for review at any point in the school year. This set is aligned to Virginia SOL standard LS.2.e.
