Sience was very intresting to learn about Middle Age science, and to see the inventions they created. They invented many new weapons to help in wars, like catapults, trebiuchet, and cannons. They also created better ways of farming with the grain windwill, which grinded up grains easily. They also created convex, and concave lenses for glasses so people could see. They created many more things but that was just a few things they invented.
