In this video we learned about many things about science. Who was it? Bill Nye the science guy. First we learned about buoyancy. Buoyancy is the act of an object floating in the ocean. There are three types of buoyancy. The first one: Positive buoyancy. Positive buoyancy is when the object floats at the surface. The next one is neutral buoyancy. This is when the object floats in the middle of the water (we recently tested this in marine science). The last one would be negative buoyancy. It is apparent that this would mean it would sink right to the bottom.
If you have two clay balls and one is in the shape of a boat the one in the shape of a boat will float and the ball will sink. This is because the shape. The ball is heavier than the boat.
(Archimedes was a Greek scientist who discovered buoyancy)
The next thing you may need to know is about swim bladders. These swim bladders help the fish go up or down in the water. Its also what makes them float. This is also how they control their buoyancy. Hot air balloons also need buoyancy on their side so they can float.
