1. 1. Archimedes ! By: Libby, Paige, Bradley, Kirsten, and Jeanette Archimedes and Pi  He drew polygons inside and outside a circle and then used Pi r squared to find the perimeter of the polygons. By using this formula, he was able to come with a very accurate approximation of Pi.
2. 2.  We would use Pi today when finding circumferences and area of circles. Archimedes and Density  Archimedes’ rules of density are used for many things, such as determining what floats, weighing objects, and especially with submarines when they travel underwater.
3. 3.  Submarines are not only the most useful type of weapon in the war, but they are also a great example of how density works. This is because when maintaining the same level under the water, they are also able to carry tons of weaponry with them without sinking. Archimedes and Buoyancy  Archimedes was bathing and discovered that when he submerged himself into the tub that water would be displaced. By collecting and weighing the displaced water helped him differentiate the weight between objects.
4. 4.  Buoyancy is used today when ships travel across the oceans to transport goods to other countries. During manufacturing, it is important to know the principles of buoyancy so that the ships don’t sink because of their weight.
