The Immune System 1: Bacterial Infection

Every second of your life you are under attack from bacteria, viruses, spores and more. This animation shows the immune system as a powerful army of cells that fights for your survival. It is a complex, beautiful and just awesome system.


I am a former junior and senior high school biology and chemistry teacher and science curriculum consultant. I have always been interested in science, particularly biology and ecology. As a child I was always asking “why?”, taking things apart to see how they worked (sometimes getting them back together), and exploring my local environment. I teach undergraduate science education courses where one of my academic interests is how we address the Nature of Science in classrooms to ensure students develop a true understanding of what science “is”, and the role science plays in our lives.
