Germs & Bacteria
During one of our hands-on investigations, 21st CCLC students learned about germs and bacteria. Students learned how to use Petri plates, swabs, and solution to collect sample cultures. Working in teams, students tested a variety of school surfaces including the kitchen sink, door handles, and hallway walls to discover the levels of bacteria. Don’t worry, RBA is safe but it doesn’t hurt to wash your hands frequently and use hand sanitizer.
