4. How can you tell? What data do you have that demonstrates your answer? Be specific. Do not use words like “it” and “molecules”. Data is specific and confirmed by a test or known information – not a guess. Give a justification for BOTH substances. 5. After the experiment has sat for 1 hour, answer which of the following substances that were inside the bag/tube have left the bag/tube and entered the water/IKI outside the bag? Substance Left the bag/tube? (Yes or no) Glucose Starch 6. How can you tell? What data do you have that demonstrates your answer? Be specific. Do not use words like “it” and “molecules”. Data is specific and confirmed by a test or known information – not a guess. Give a justification for BOTH substances. 7. Based on your observations from the experiment, rank the following four molecules from the smallest to the largest molecule. If you need to, look up the molecular weights of each: glucose molecules, water molecules, IKI molecules, and starch molecules. 8. What results would you expect if the experiment started with a glucose and IKI solution inside the bag and only starch and water outside? Discuss any color changes you might see or changes on the test strip. Be specific in your wording. Don’t use the word “it” or “color change”. State exactly what would enter the bag/tube, what would leave the bag/tube, and what colors would change based on the tests you used above for these substances.
