Botanical Superheroes: Investigating the Antibacterial Properties of Plant Extracts


In this lesson, students learn that bacteria can cause illness, including neurological diseases such as meningitis. In the lab portion, they examine whether some plant extracts are effective at slowing down the growth of bacteria. Students will expose bacteria to penicillin, water, and several different plant extracts (including garlic juice and the essential oils of tea tree and clove) to determine whether plant extracts inhibit bacterial growth.
