INTRODUCTION:
a. Background Information: In a paragraph below, please provide necessary vocab words and
definitions for the molecules we are looking at in the lab (ex: macromolecule, lipid, carbohydrates,
proteins). Please also provide the function of each of the molecules (why do we need protein, lipids,
carbs?) Please provide how this lab connected to what we are learning about in class right now.
The four macromolecules are ……… A macromolecule is…….. Carbohydrates are….. Lipids
are……. Proteins are……. The function of a carbohydrate is…… The function of a protein is….. The
function of a lipid is…… This lab connects to class because the students are learning…….

b. Written Description of Data:
In a paragraph below, please describe what is shown in your data table (in terms of the results).
Which foods tested positive for lipids? Proteins? Simple carbs? Complex Carbs?
The data table shows…..Whole milk tested positive for……… Crackers tested positive for…….. Beans
tested positive for……. The food sample tested positive for……. The following foods contained all
macromolecules: The following foods only contained one macromolecule: The following macromolecule
(s) were found in all foods:
c. Qualitative Data Information:
In a paragraph below, please describe what the reactions looked like during each test. What were
the color changes? Did any show some surprising reactions? This is where you talk about the physical
observations!
For the starch test, the positive control turned…… For the protein test, the positive control
turned….. For the lipids test, the positive control turned….. For the simple sugar test, the positive control
turned….. The negative control (water) was…… The most interesting color change for the starch test
was….. The most interesting color change for the protein test was….. The most interesting change for the
lipids test was….. The most interesting color change for the simple sugar test was…. The group was the
most surprised about …….. reaction. The most interesting test (out of the four—starch, protein, lipids, or
simple sugar) was ………. because……….
