Applied Strategy: Peer Instruction & Think-pair-share
Single class period (< 90 mins)
The aim of the activity is to increase students' understanding of molecules' movement through the cell membrane while using their knowledge of molecules' shape and polarity.
The cellular and physiological effects of molecules greatly depend on its absorption by the cells, students can apply this knowledge to understand the effect of many molecules, drugs, pathogens, vaccines, etc. Acting as either part of the membrane or as specific molecules wanting to cross the membrane, the class acts out membrane transport. As each molecule (student) passes through the membrane, other students provide immediate feedback on whether the process was correctly carried out. ...

The cellular and physiological effects of molecules greatly depend on its absorption by the cells, students can apply this knowledge to understand the effect of many molecules, drugs, pathogens, vaccines, etc. Acting as either part of the membrane or as specific molecules wanting to cross the membrane, the class acts out membrane transport. As each molecule (student) passes through the membrane, other students provide immediate feedback on whether the process was correctly carried out. Afterwards, the class creates a summary table together or individually for homework.
This activity can be described as peer learning, while students have to use knowledge from various parts of the biology and chemistry courses, which some students may recall more than others. The activity can be done in many phases. The first phase described here can be done in 30-45 minutes, after a lesson on membrane transport.
