Lab: Osmosis & Diffusion . Salt water has about 10-20 times the molecules than what is in the Gummi Bear. Place the gummy bears in cups of water – one per student – and set aside. Gummy Bear Lab By Alex Early Liz Marth Hannah Verplanck Liv Goss Question: What will happen to gummy bears when they are placed into different solutions? Instructions for the Gummy Bear Osmosis Experiment Label each glass with its contents: water, salt water, sugar water, etc. Problem: Where is the concentration of H2O molecules highest: tap water, salt water, sugar water, or in the gummi bears? It's fun and VERY easy! The first experiment involves soaking your gummy bears overnight in plain water. The colour loss and delicateness were both due to the fact that the gummy bear is made mostly out of sugar, and that some of the sugar dissolved in the water overnight, causing ! Gummi. Bears. Explain any change in color in the bears or their solutions. Describe the movement of water that produced the results. In terms of size, the gummy bear had become larger because it absorbed water overnight. Osmosis is the diffusion of water across a semipermeable membrane. Fill the glass labeled sugar water with one-half cup water. Water had soaked into the gummy bear causing it to expand. Purpose: To investigate the movement of water into and out of a Gummi Bear. Because of osmosis, water molecules move to an area with more solute in it to balance things. The catch is that the water is locked up in the candy and can’t move. Gummy Bear Osmosis Lab Report Purpose: The purpose of this lab is to measure the amount of Osmosis in different types of solutions and to see how a cell would react in different types of solutions. Due to the process of osmosis, i.e., the movement of water molecules through a selectively permeable membrane from an area of high concentration to that of a lower concentration, the bear starts to grow. The ingredients of gummy bears are sugar, water, and gelatin, with little water content. Learn how Osmosis, Diffusion, and Semi-permeable Membranes work by conducting this experiment!!! Fill the glass labeled salt water with one-half cup water. How will we calculate if the water moved at all? in. Use gummy bears to demonstrate osmosis with this simple science experiment. Again, water moves to dilute, so water will leave the gummy bear and move out into the cup of salt water, causing the gummy bear to shrink. Believe it or not, osmosis also happens when you drop gummy bears into water, revealing the most basic inner workings of your body’s cells. The gummy bear’s size will decrease because of osmosis. Water should have moved out of the gummy bear since there is more salt or sugar in the liquid. The Gummi Bear can’t shrink further, so it stays about the same size. Fill the glass labeled water with one-half cup plain water. Eventually, the sugar concentration inside the gummy bear is the same as the sugar concentration inside the liquid, and osmosis stops. Prediction: We think that the gummy bear in the distilled water will get to be the biggest because the sugar will evem out in If you truly saturated your salt or sugar solutions, your gummy bear should shrink. Now the gummy bear is full of water and it is placed in salt water. Prior to soaking, have your students measure the height, width, and depth of the gummy bear, and record this information in their lab books. And where will it move because of that? The dependent variable in this lab is what the size of the gummy bears are after being put into the ... Sugar c. Salt and Sugar d. Water 5.
