Conclusion: My data clearly shows the differences between the height, width, and weight... ...Abstract [5] Although osmosis does not require input of energy, it does use kinetic energy [6] and can be made to do work. There are three types of movement of particals across the cell: diffusion(and also facilitated diffusion), osmosis and active transport. Blog. We believe the gummy bear experiment) to see if we would get different results. So, the water will travel out of the potato cells and into the surrounding solution. Students will analyze how solute size and concentration affect diffusion across semi-permeable membranes and how these processes affect water potential. Each cell is surrounded by a membrane that protects the cell by keeping the cells parts inside and keeping other things outside. Osmosis is an important process to cells because the cells are continuously trying to achieve concentration equilibrium. It would be made up of tiny, living units called cells. Bears will soak in water overnight, then students will record second set of measurements, calculate % changes, and graph percent changes. Terms in this set (8) gummy bears. _____ This Gummy Bear Osmosis experiment takes less than an hour to set up, but the actual experiment runs for 48 hours. Those are hypertonic, hypotonic, and isotonic. In my preliminary experiment i used 0 to 3 molar, 3 molar got lighter and 0 molar got heavier. Taylor Biology 6th period 2/12/15 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. The controlled variable is the gummy bear. Experiment with Gummy Bear Osmosis In an experiment, students will u se their senses to observe differences AND record changes on a data sheet. In general, these membranes are impermeable to large and polar molecules, such as ions, proteins, and polysaccharides, while being permeable to non-polar and/or hydrophobic molecules like lipids as well as to small molecules like oxygen, carbon dioxide, nitrogen, nitric oxide, etc. Drown 1 bear in distilled water and drown the other in 40% salt solution.
