Bacteria and Antibiotic Resistance Lab

My students need petri dishes, agar and antibiotic disks to do an inquiry based lab that lets them culture bacteria and determine antibiotic resistance.

My Students

My students learn science by doing science. In this bacteria lab - students will realize just how much bacteria is all around them - on their desks - books - pencils - keys. Bacteria comes "alive" for them when they see the cultures on the petri dishes.

My school is a Title I school serving a diverse student population.

Many of my students do not have any practical lab experience and I am determined to change that! My students want to learn science. They ask intriguing questions and many can relate science themes to their lives. Two of my classes are ELL - with two full time interpreters for English and Creole speaking students. Sometimes I cannot cover the content in one day that I would normally in the other classes so these two classes have had their fair share of "homework." What impressed me the most was when I had 100% participation in completing a homework assignment from 25 students - every one did their homework paper on water! I was almost in tears when I was collecting the papers. The effort they put in and the attempt to learn the material has motivated me personally to try and overcome the language barriers in the science curriculum.

My Project

I am requesting petri dishes, agar to put in them and antibiotic disks. I will personally pour 200 petri dishes for this lab but I will not be alone because once the students hear I need help, I will have several back in the "kitchen" with lab coats on pouring agar plates! The students will then go around the school and "collect" bacteria using q-tips (its fun to have them swab the principal). We also test which bacteria are resistant to specific antibiotics using the disks. I also have the students bring in their favorite mouthwash. We soak disks in mouthwash and determine which mouthwash was the most bacterial resistant. What is great about this lab is the bacteria and where it can be found - everywhere! The students are so grossed out when they see colonies of bacteria from the surfaces they swabbed. It makes them realize the hidden world around us.

This lab is important for my students understanding of microbiology.

I hope to engage the kids and make future scientists/health care providers with this type of a lab. I need to do hands-on labs in science and the materials are expensive! Students will never forget this lab. They will always look back on this lab and their perspective on bacteria and the hidden world around them will be forever changed. They will never forget the colonies of bacteria they grew from the school.
