Description
In this remote-learning ready, google slides lesson, students use evidence to determine the nature of the cell membrane, discover how diffusion works, and then apply that knowledge to real life examples that occur in the human body. I have listed the specific student tasks included in this lesson below.
1. Students examine a phospholipid molecule to determine which end is hydrophilic, and which is hydrophobic
2. Students examine the actual data from Gorter and Grendel's 1920's experiment to show that the cell membrane is composed of two layers
3. Students perform two simple experiments involving diffusion (spraying perfume in a room and dropping food coloring in a cup) and draw models to explain what the molecules are doing in each example. (For remote learning, I tell my students that they may perform the investigation at home, or they may use their prior experience and imaginations to create their drawings.)
4. Students learn that while molecules diffuse from a high to a low concentration across a membrane, large molecules may be blocked. This is reinforced by a silly example- students are asked which animals (out of the choices of a mouse, a dog, and an elephant) can fit through a door.
5. Students apply their knowledge to 10 independent work problems regarding diffusion across a membrane. Gas exchange and digestion are used as examples.
Thank you for your purchase, and happy teaching!
