Lab Report: Experiment 2 Testing for Starch 1. Formulate a hypothesis regarding the presence of starch in different samples being tested. 2. Based on your hypothesis, make predictions on the outcome of the iodine reaction for each solution. 3. Report the data for the solutions tested in the Table 2.3. Indicate in the table which unknown solution was used. Table 2.3. The iodine test data for solutions. Starch Present? Final Color lodine Solution (yes or no) 1-2 drops 0.5 mL glucose 1-2 drops 0.5 mL starch 1-2 drops 0.5 mL albumin 1-2 drops 0.5 mL distilled water 1-2 drops 0.5 mL unknown 4. Did the unknown solution contain reducing starch? Laboratory 2 Macromolecules E Beport the data for the iodine test of the potato and onion sample the Table 2.4 Table 2.4. The iodine test data for plant samples. Final color Initial color Sample Starch presence (Y/N) Potato Onion Based on your data, which of the two plants-potato or onion-stores energy in the form 6. of starch? 7. Evaluate your hypothesis. Do your data support, reject, or partially support your hypothesis? If your data did not fully agree with your predictions, hypothesize why and modify your hypothesis accordingly.

Which question will your experiment investigate? (select one and delete the others) How does temperature affect how lactase drops work to break down lactose into glucose and galactose? How does pH affect how lactase drops work to break down lactose into glucose and galactose? How does agitation (movement) affect how lactase drops work to break down lactose into glucose and galactose? What variable will you change in this experiment? This is also called the Independent variable. How will you change it? What variable will you measure in this experiment to determine the effect of the variable you changed? This is also called the Dependent variable. How will you measure it? What variables will you keep the same in this experiment? Check off the items in this list that you would use for this experiment. You may add any items you feel you would need. O Skim milk (which contains lactose) O Lactase drops O Graduated cylinder O Eye dropper O Ice cubes O pH paper O Hot plate O Mixing spoon O…
