Curated OER
The Jelly Bean Problem
Students are challenged to eat some candy as a cell would need to do it. By solving this problem students simulate the cell process called endocytosis. They think about some of the problems that arise when a cell ingests food.
Curated OER
Diffusion Across a Selectively Permeable Membrane
Learners investigate how water passes through cell membranes. In this biology instructional activity, students differentiate osmosis and diffusion. They illustrate the movement of water in both processes.
Curated OER
Study of the Cell
Learners draw a diagram to show the fluid mosaic model of a membrane. They explain how hydrophobic and hydrophilic properties help membranes hold their shape. They identify the functions of different cell membrane proteins as well.
