Demonstrate the ratio of surface area to volume in your high school class by using phenolphthalein, gelatin, and an onion. Intrigue the class by leading a discussion on osmosis and diffusion, then making "scientific jello." Participants...
Curated OER
Cell physiology and chemistry
Students design an experiment to discriminate between chemical diffusion, osmosis, facilitated diffusion and active transport through a membrane. Be specific about predictions and interpretations!
Curated OER
Osmosis
Students explore diffusion and active transport. They observe the effects of eggs in vinegar and predict what will happen when eggs are placed in corn syrup with food coloring. Students complete worksheets which lead them to describe...
