My project is about the history of scientific theories. This means that it's about what scientists believed as true over time. The main theories that I'm focusing on are ones there were held to be true, but then discovered to be false. Two very important theories were geocentric theory, and spontaneous generation. I explained how each of these, and 3 more theories were proven false, and how this changed the world. I did this project because I think it's an interesting topic, and think it has to be considered in the future. At the end of the presentation I talk about how this could relate to modern day, and everything that we have learned could be proven wrong.
