Even though we can't see them, some bacteria are floating in the air all around us. How did they get there? Are they doing anything? Are they harmful or helpful to us? Together we'll try and answer these questions as well as try and understand how these bacteria might be shaping the weather of our entire planet.

Have you ever wondered why we fart? Ever thought about why it smells bad sometimes but not always? This class will explore these questions and everything about flatulence you could possibly want to know. We'll show that, because of bacteria that live in our bodies, even though we are the ones forced to have smelt it, we may not be the ones who have dealt it.
