These are the instructions for the food coloring lab. The integration of science was due to a collaboration with a 7th grade science teacher. The use of the EDD form is a fabulous way to highlight the science inherent in cooking. Her students and mine recently shared a lab - this lesson is another opportunity for a hands on partnership.

1. Food Science: Food Coloring
Food Coloring Experiment
Recipe #1 OR Recipe #2 OR Recipe #3 OR Recipe #4
Instructions
Your team is going to be assigned a food coloring recipe to follow. Your team is to follow the
instructions associated with creating your version of food coloring. There are 4 different recipes.
At the end of the lab we are, as a class, going to contrast and compare the recipes and determine
which one(s) are the best. (Don’t worry! You will be given a copy of all of the recipes used in this lab.)
Part 1:
1. Complete the Kitchen Lab Assignments form
2. Make the cookies
a. Wrap the cookies in plastic
b. Shrink wrap the cookies
c. Write your names, the period, and the date on a piece of masking tape
d. Put the tape on the shrink wrap
e. Freeze the cookies
Part 2:
3. Complete 1-4 and 6-7 of the Part 1-EDD
4. Conduct the lab
a. Make the food coloring using the recipe/technique assigned to your team
b. Give your food color to the “Color Analysis Team”
i. Using the survey form, analyze your food coloring samples
ii. Store your materials away for our next lab
1. Pack your completed contents into an assigned custard cup
2. Plastic wrap your custard cups
3. Label your custard cups with the Period, your table #, the date you
completed the lab, and the name of your lab reference person
4. Vacuum pack your custard cup
5. Complete #5 and 8 on your Part 1-EDD form
a. Take a picture of your Part 1-EDD form and upload it into Google Classroom
b. File the Part 1-EDD form in your class folder

2. Part 3:
6. Read at the material on pages 9 and 10 of the “Natural Food Coloring” book.
a. Read the information on page 9.
i. Record your findings in Cornell notes
ii. If you have not recorded your Cornell notes electronically, make a copy of
your notes and upload them into Google Classroom.
1. Put your original form in your classroom file folder
b. Open up a google document and answer the questions on page 10
i. This part of the project is individual and can be done at home/during
lunch/after school on Google Classroom
Part 4:
7. The “Color Analysis Teams”
a. Pull the food coloring from the refrigerator
b. Allow the food coloring to warm up for 10 minutes before conducting your
experiment
c. Get your Part 2-EDD form
d. Using the survey form, analyze your food coloring samples
i. Upload a copy of your completed survey form to Google Classroom
e. Complete #5 on your Part 2-EDD form
i. Pull your Part 1-EDD form
ii. Compare your results
iii. Complete #8 on your Part 2-EDD form.
1. Take a picture and upload to Google Classroom

Title:
1. We are measuring the effect source ingredients have on making dense food coloring.
2. We are measuring the effect source ingredients have on the taste of food coloring.
3. We are measuring the effect source ingredients have on food coloring when added to icing.
4. We are measuring the effect of time on the above attributes.
