Beefy Antibiotics: What's Lurking in Your Dinner? | Science Fair Projects | STEM Projects
Are you eating beef with antibiotics? Find out with this science project! You'll swab agar dishes with juice from standard and natural ground beef, incubate them, and observe the growth of bacteria. Then you'll compare the results to see if there's a difference between the two types of beef.

Hypothesis

The hypothesis is that the standard ground beef will show usage of antibiotic additives while the naturally grown ground beef will not.

Method & Materials

You will swab five agar dishes with the juice from standard and natural ground beef, and one agar dish as a control. Then you will incubate all six agar plates over a period of five days.
You will need agar dishes, standard and natural ground beef, and a control.

Results

The results showed that the naturally grown ground beef averaged 31 percent of their entire agar plates, while the standard ground beefs averaged 30 percent. The control averaged 20 percent. This suggests that the naturally grown ground beef had little or no antibiotic additives, while the standard ground beef had more.

Why do this project?

This science project is interesting because it shows the difference between naturally grown ground beef and standard ground beef in terms of antibiotic additives.

Also Consider

Experiment variations to consider include testing different types of beef, such as grass-fed beef, or testing different types of antibiotic additives.
