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.

Pros

• Very visual demonstrations of diffusion
• Using candy for the activity adds a fun factor
• Worksheets and lesson plan can be edited for your specific needs

Cons

• The worksheet has an unexplained title (Pre MacMod and Post Macmod), instructions for drawing molecules during the air freshener demonstration do not make sense; make corrections as needed before use
