The Alien Egg Experiment
Amaze classes with the fact that pruny fingers after a bath are actually the result of osmosis—thanks to the water from the tub. Using an egg, vinegar, and corn syrup, the video teaches about osmosis using an interesting demonstration....

Osmoregulation
Because salmon live both in salt and freshwater, they have physical (different urine concentrations) and behavioral (drinking more or less water) adaptations to maintain osmolality. In this osmoregulation video, the instructor...

Osmosis Demo
Don't you wish you could absorb knowledge through osmosis? The video begins by defining osmosis, explores how water flows from a hypotonic to a hypertonic concentration, reaching an isotonic level. Learners then see a demonstration of...
