Product Details

No more confusion about diffusion and equilibrium! In this interactive class demonstration, students discover that diffusion is due to molecules moving randomly about and that the “final” state of equilibrium is really a dynamic condition. Transferring “molecules” across a simulated cell membrane provides a model for diffusion down a concentration gradient. The random motion of molecules, however, means that some molecules are transferred back. As students move the molecules back and forth at a prescribed rate, they see the motion never stops! Kit includes complete instructions with reproducible student handouts, data table transparency sheet, valuable Teacher NotesSuper Value Kit is complete for 30 students working in pairs, and all materials are reusable!
