Beschrijving

Students move ball bearings (2mm, 4mm, and 5mm) through a membrane to demonstrate how molecules move through a membrane. The divots show where the ball bearings start and finish. Students will need to turn the "protein" to demonstrate active transport. The big green circle is where I glue a magnet to store the ball bearings when not in use.
