Great hands-on lab where students can see the effectiveness of antibiotics and disinfectants in action. Students will set up two petri dishes to test the effectiveness of three types of antibiotics and three types of disinfectants. They will analyze their results and complete a discussion section.
My students love this lab because they can see the results after 48-72 hours. It also allows them to set up an experiment, record data, and analyze their data. This lab also aligns with the NGSS standards.
