Beginning biologists explore passive transport through two demonstrations and a hands-on inquiry. Spray air freshener from one spot in the classroom and have class members raise their hands as the scent reaches them. Also, place a teabag into a clear glass container of hot water for them to observe. The accompanying activity involves individuals soaking a bear-shaped gummy candy in distilled water overnight, comparing before and after measurements of mass and length. This resource would support your life science lesson on passive transport.
