Initially, I though it didn't move at all, but when i poured out the solution, I had to change my mind. ]]> 2020-06-30 17:06:38 UTC https://padlet.com/ddrobi/tqwgp74whswuf1w2/wish/644182182 The photo that changed my mind about the experiment ddrobi https://padlet.com/ddrobi/tqwgp74whswuf1w2/wish/644186813 After I poured out the solution, I noticed that the gelatin level rose above the initial line that I made yesterday. Therefore, I had to conclude that maybe the acetic acid leached all the to the bottom and was able to push the gelatin upwards. This was not seen in the test tube with only the methylene blue. This was seen in the test tube with both solutions, so its only logical to assume that the acetic acid is responsible for this. With that, the unexpected winner of the gelatin race is acetic acid. ]]> 2020-06-30 17:11:36 UTC https://padlet.com/ddrobi/tqwgp74whswuf1w2/wish/644186813 Initial placement of the bag ddrobi https://padlet.com/ddrobi/tqwgp74whswuf1w2/wish/644195036 2020-06-30 17:21:18 UTC https://padlet.com/ddrobi/tqwgp74whswuf1w2/wish/644195036 ddrobi https://padlet.com/ddrobi/tqwgp74whswuf1w2/wish/644196183 The purpose of this experiment is to see how the size of a molecule affects how it can pass through a membrane]]> 2020-06-30 17:22:34 UTC https://padlet.com/ddrobi/tqwgp74whswuf1w2/wish/644196183 One Hour Later ddrobi https://padlet.com/ddrobi/tqwgp74whswuf1w2/wish/644198798 2020-06-30 17:25:26 UTC https://padlet.com/ddrobi/tqwgp74whswuf1w2/wish/644198798 Using a glucose testing strip, tI was able to see that glucose was able to pass through the dialysis bag into the water outside the bag. The starch settled to the bottom of the dialysis bag and never made it out of the bag. The negative KI test confirmed this. After the hour, the beaker was sitting in a puddle of water, so I am concluding that water entered the bag and leached out the open top. ddrobi https://padlet.com/ddrobi/tqwgp74whswuf1w2/wish/644201080 2020-06-30 17:27:26 UTC https://padlet.com/ddrobi/tqwgp74whswuf1w2/wish/644201080 Initial Set-up ddrobi https://padlet.com/ddrobi/tqwgp74whswuf1w2/wish/644207147 All fours bags contain 10 ml of water with different concentrations of sucrose.
