The students will have science fair project to do at the end of the year, and I wanted to take them step by step through the process so that they will know exactly what to do for their projects. Get Essay The salt water gummy shrunk because salt soaks up water and other substances. The gummy bear does not continue to grow after around 2 weeks. Research Hypothesis: The gummy bear will dissolve in the water due to the fact that most gummy bears are made out of pure sugar. Salted water had much higher concentration than the pure one, so less water went into the gummy bear (in gummy bears there is some water, but not much, so the concentration is very high). I was looking on Pinterest for a lab to use with my students to teach them the scientific method. During osmosis, there is a stage called equilibrium which indicates that the concentration of a solute in water is the same on both sides of the semipermeable membrane. Title: Gummy Bear Osmosis Objective: This experiment revolves around the concept of osmosis. Tap water? This week, the organic chemistry lab I'm TA'ing dehydrated. We can use reverse osmosis to desalinate salt water, we have to apply very high pressure to force water through a semipermeable membrane. After conducting more experiments with different amounts of salt ( plus research ) I can conclude that NO MATTER how much salt you put into your solution the gummy bear will NOT expand. This is when a solution has a high solute level. Its effects can be seen in all organisms and in some abiotic factors.

The lab is using the gummy bears to show how cells work because cells can take in more and less concentrated solutions just as gummy bears do but it leaves a different appearance depending on the solution. In conclusion my hypothesis was partly correct, the gummy did absorb more tap water and the salt water did decrease the size of the gummy but, the sugar water gummy did not increase as much I thought it would have, it absorbed very very little so it didn’t change any appearance much at all. Diffusion is the movement of molecules from higher-concentrations to lower-concentrations in order for the molecules to remain in constant equilibrium. She is a nursing student studying at the University of New Hampshire. We call the membrane selectively permeable because it decides what comes in and out. They will use actual measurements to record changes whenever possible. Background Research: If you are thinking that water has filled out the gummy bear then you are absolutely right. osmosis. In this lab diffusion can be taken place just as cells o, the gummy take in the solutions and eventually the solution will escape if not kept in solution. Water travels from an area of high water density through the gelatin to an area of low water density, swelling the candy. What happens when you put gummy bears in milk? (You’ll need around 7-9 tablespoons.)
