Problem Statement: Day 1: What organic or inorganic compounds (starch, protein, glucose, NACL) are in an unknown solution. Day 2: Which of the substances (starch or NACL) will be able to diffuse out of the plastic bag or “cell” if you will. Hypothesis: If the starch and NACL compounds do diffuse through the plastic bag, then we know that these substances will diffuse in an actual cell also. Procedure: Day 1 Materials Needed: Dialysis tubing, thread, 100 mL beaker, 10 …showed first 75 words of 1090 total…

…showed last 75 words of 1090 total…the result s if large quantities of chemicals were lying at the bottom of the tube unnoticed. It is important to make sure that no other reagents or chemicals are added to the experiment. However, I do think that our test tubes were fairly clean. “How accurate are our results,” you ask. Well, I do believe they are accurate because we tried our best to eliminate all possible sources of error for the most part.
