Another Day, Another Lesson

First I will start with science. Today in science we looked at buoyancy and page 134.
On page 134 it states how a solid pushes particles out of its way to get through. The reason the solid doesn't do this is because it is made of a lattice structure. Also it is held together with the force of attraction which is like a magnetic force. In order to break the magnetic force you have to add kinetic energy, heat, which will get the particles moving and break the lattice.

In this picture it shows a finger and a piece of cheese (our fluid)
When we push our finger in, the fluid under our finger will compact.

Now let's say that there are more particles in the cheese (red dots). If you push on the fluid now that it is denser your finger will bounce back which is Buoyancy.(buoyancy defined by black arrows)
