The experiment helps students with learning about density, specific gravity, and the application of Archimedes’ principle. These concepts were incorporate into three parts of the experiment. Specifically, it was expected for the regular object and irregular object part of the experiment for the buoyant force and the weight of the displaced water to be equal to each other. The results were unexpected since they did not end up equaling to each other.
Objective
The objective of this experiment is to learn about density, specific gravity, and applying Archimedes’ principle to different solids and liquids. Students will also observe how the buoyant force is exerted on an object that is submerged in a liquid.

Specific gravity is unitless and is useful in telling us if the object will sink or float in the reference substance. For example, when an object is thrown into water, it can either sink or float. If the calculated specific gravity is greater than 1 (the density of water is equal to 1), then the object will sink. If the calculated specific gravity is less than 1, then the object will float. If the specific gravity is equal to 1, then the object will either sink or …show more content…
The first part involves the regular object, the second part involves the irregular object, and the third part is specific gravity of a liquid.
Regular Object and Irregular Object
1) Using the ruler, measure the dimension of the metal cylinder (regular object). Also record what the object is made of.
2) Find the weight of the metal cylinder using the hanging scale. Tie a loop around the metal cylinder and the hanging scale using the string.
3) Put regular water into the displacement vessel. Put enough water where the water line is below the sprout of the displacement vessel.
4) Put the small can under the opening of the displacement vessel’s sprout. This is where the displaced water will be collected.
5) Now place the metal cylinder (still attached to the string onto the hanging scale) into the displacement vessel.
6) Make sure the metal cylinder is completely underwater and ensure the cylinder is not touching the bottom or sides of the displacement
