  1. NYS Diffusion Lab Movement Through a Membrane

  2. The Benedict’s Test • http://youtu.be/QU0VBcHnQOk Benedict’s solution is BLUE and will turn YELLOW, ORANGE, GREEN, OR RED IN THE PRESENCE OF A SIMPLE SUGAR (MONOSACCHARIDE)

  3. OSMOSIS OSMOSIS is the diffusion of water Adding SALT water will make a cell SHRINK Adding DISTILLED WATER will cause a cell to SWELL back up

  5. Diffusion Diffusion is the movement of molecules from high to low concentration.

  6. Iodine, Glucose, Starch

  7. Results Starch + Lugol’s Iodine = PURPLE/ BLUE BLACK GLUCOSE + Glucose Test Strip = Turns GREEN STARCH DID NOT DIFFUSE BECAUSE IT WAS TOO BIG!
