Celebrate Hispanic & Latinx Heritage Month

This project is a part of the Hispanic & Latinx Heritage Month celebration because it supports a Latino teacher or a school where the majority of students are Latino.

My Students

I teach 10th grade biology in a public high-school in Los Angeles Unified School District. I have students from all ability levels that study biology as part of their mandatory graduation credit.

My students are from a diverse ethnic and academic background, but all are curious, and ready to learn!

Many of my students receive free or reduced-fee lunch. Many are getting to school by bus from distant neighborhoods in Los Angeles. Most of my students belong to our Architecture, Digital Design and Film magnet school, where they get trained as future professionals in these technical arts. Their interest in science is largely dependent on the quality of instruction given to them, and it is my goal to capture their minds from the first minute they enter my class to the last day of school.

I believe that my students, no matter what grades they earned in previous years, or even in my course, all have valuable ideas on how the world works, and these ideas are the most important materials in my instruction.

My Project

My students learn biology through the study of phenmena that are often part of their daily life. One phenomenon we study in depth is the unfortunate evolution of antibiotic resistant bacteria, or in short - 'super bugs' that are no longer killed by our medicine. To understand how this happens, my students will first take a swab test of bacteria on surfaces around the school campus, and in another experiment, they will expose E,Coli bacteria to antibiotics and see how the bacteria population shifts to one that doe snot get killed by the medicine.

In order to observe the bacteria, my students will need to use the swab sticks to pick up the bacteria, and they'll use nutrient (LB) agar in Petri dishes, to watch the bacteira grow.

By growing bacteria to the millions on the Petri dish medium students will realize how common bacteia are in their lives, and what could happen if we overuse antibiotics. Aside from antibiotic resistance, my students will learn first hand how bacteria compete with one another on space, and sometimes food.
