Chicken Nugget Challenge!

Purpose: To evaluate which of the following brand of chicken nuggets have the most amount of protein: McDonald's, Wendy's, Tyson, or Chick-Fil-A.

What do we (the experimenters) think will happen?

We hypothesize that the Chick-Fil-A brand chicken nuggets will have the most amount of protein (real traceable chicken) compared to McDonald's, Wendy's, and Tyson.

Analysis and Conclusion

For our design lab, our group decided that we would test the general protein content in chicken nuggets from four fast food restaurants. Our hypothesis stated that the chicken nuggets from Chick-Fil-A would have the highest protein content compared to that of Wendy's, McDonald's, and Tyson. To test our hypothesis, we separately blended up three chicken nuggets from Wendy’s, McDonald’s, Tyson, and Chick-Fil-A with 80 mL of water and performed a biuret test and a urine strip test a total of three trials for accurate data. All of the nuggets from each fast food restaurant did exhibit traces of protein as we saw through the biuret test since the solution turned lavender. After testing for general protein content, we used urine strips to get more specific numerical data. It turned out that our hypothesis was correct and Chick-Fil-A nuggets did in fact have the most protein(>100 mg) and the other nuggets only had either 30-100 mg or just a small trace of protein.

Pie chart


We are not associated with any of the brands we used in our experiment. We did have some sources of inaccuracies since the data we collected had to do with color depiction. What we interpreted as lavender may not be consistent with others, as well as the color of green that appeared on the urine test strips. As experimenters, we cannot tell you exactly what to do as we are not health experts, however the data collected through the experiment can reveal some powerful recommendations to live a healthier life.


The article "Tips to Make Fast Food Friendlier for Kids." by the American Heart Association recommends that it is best to feed children chicken without skin, so grilled would be the healthier alternative. Chicken nuggets usually have a high content of sodium and fat. "The Autopsy of Chicken Nuggets Reads "Chicken Little"" by the American Journal of Medicine did a study which claims that chicken nuggets only have nineteen percent protein, so it is best to eat these types of fast foods in moderation to none. It does not provide healthy nutrition for the body.
