Project Description
Students worked to better understand the places in our school that have the most bacteria on them, and which disinfectant/sanitizer is the most effective at killing bacteria. Students picked locations in the school after doing some base research about which places in houses and public spaces are the dirtiest (primary scientific research). They then collected ubiquitous bacteria swabs from their locations and used agar plates to streak bacteria cultures. We then grew them in a modified incubator for a week. Then students measured bacteria growth by counting the number of bacteria colonies and the size of the largest colony.
How did this positively impact the community? How was it shared?
Reflection: What was the biggest challenge? What was the most rewarding aspect of this project?
Any advice for a teacher or student that is implementing a PBE project for the first time?
