Archimedes' Principle
Archimedes' principle states that the buoyant force on an immersed object is equal to the weight of the fluid it displaces.
The image below accurately depicts Archimedes' principle because when the 7 kg weight is submerged in the water, it displaces 3 kg worth of water. The displaced water is shown in a bowl to the side of the tank with the weight in it. The objects weight becomes 4 kg after the weight is placed in the water, and it has a buoyant force of 3 kg which is equal to the weight of the displaced fluid.

Pascal's Principle
Pascal's principle states that changes in pressure at any point in an enclosed fluid at rest are transmitted undiminished to all points in the fluid and act in all directions.
The image below accurately depicts Pascal's principle because the pressure acting down on the smaller platform lifts the larger platform with the car up. The pressure on the smaller platform is equal to the pressure exerted on any other surface, converting the small force to a larger force on a larger area.

Bernoulli's Principle
Benoulli's principle in its simplest form states that when the speed of a fluid increases, pressure in the fluid decreases.
The image below accurately depicts Bernoulli's principle because there is a lower pressure caused by a faster air speed on the top of the object, and a higher pressure caused by a slower speed on the bottom of the object. The higher pressure on the bottom of the object causes it to lift up or float because it is greater than the lower pressure on the top of the object. The air on top of the object has to speed up in order to meet the air current on the bottom of the object.
