26 27 X Food Test Experiment: Hypothesis (for unknown Sample): Conclusion: Known Samples Food Sample Observations (picture and words) Grease Stain? Iodide Color Change? Nitric Acid Color Change? Unknown Sample X 26 27

Procedures: Testing for Lipids Place a small piece of 3 samples on top of a paper napkin. Leave it there for a minute. Make an observation for each sample and write it on your chart (a picture and some words) Move the food samples at least 2 inches above or below where you initially placed the sample. If there is a grease stain on the napkin, we can assume the food sample(s) contains the following macromolecule: Lipids! Record on your chart (Yes or No)

Procedures: Testing for Carbohydrates 4. Place another small piece of all 3 samples on a paper napkin. Place 3 drops of iodide on your food samples. If the iodide changes color, then you can assume that the food sample(s) contains the following macromolecule: Carbohydrates! Record on your chart whether or not your sample changed color

Procedures: Testing for Proteins 6. Place yet another small sample of the same 3 food sample. Your co-teacher will place a drop of nitric acid on your food samples. If the drops of nitric acid changes color, then you can assume that your sample(s) contain the following macromolecule: Proteins. Record whether or not your sample changed color.

Left Side Hypothesis: Form a hypothesis about your unknown. What kind of macromolecules do you think the unknown contains? Do you think there will be a grease stain or/and color change?

What is a conclusion? The final step in the scientific method. a summary of the experiment's results Based on your results was your hypothesis Rejected or supported? Why?
