This reinforcement worksheet was designed for introductory biology, to help students learn concepts related to cell transport across the membrane. Words include osmosis, diffusion, hypertonic, and hypotonic, semipermeable, and active and passive transport. The exercise has vocabulary and a list of sentences or definitions for students to match to the words. I use google slides and guided notes to present the lesson with a Cystic Fibrosis as the guiding question and phenomenon.
Students do other exercises with this unit, such as Investigation: How Can Diffusion Be Observed, where students place starch in a bag and see how iodine will pass through the bag and turn the starch purple.
I usually do these types of reinforcement activities during class, and have students first try to complete it as a practice quiz. Then students either work in groups or pairs to complete the words that they are unsure about. The worksheet can be projected onto the board and answers can be checked.
