The objective of this experiment is to investigate and test Archimedes’ principle by

directly measuring the buoyant force acting on a submerged object. Also, it was able to

determine the specific gravity for total 4 trials.

A balance was used to measure the weights and a metal block placing on this balance. A

container with an open spout was used to measure the weight. A beaker was used to contain

water and weight. An aluminum can was acted as a ship. Sand was used to measure the weight of

the ship and string was used to hold the metal block.

[Part 1] Verification of Archimede’s principle

The rod was held up the balance beam and a string was tied with the metal block on the

left side. The balance may not be calibrated yet, so calibrate the balance by making sure both

sides were equal. Once the balance was equalized, a 600 mL beaker that’s filled with water was

placed on the opposite side of the string. The block with the string was placed into the 600mL

beaker. Now that the balance was uneven again, some weights were placed to make the

adjustment with the balance. Most importantly, the block was completely submerged in the water

with the balanced weight in this procedure.

[Part 2] Predicting the Load of a “Ship”

A large beaker was filled up with water. The weight and height of a medium sized beaker

were measured and recorded in the lab notebook. A line should be drawn at the 6 cm mark of the

3

medium sized beaker. An aluminum as the function of a ship was placed into the large beaker

and some weights were added into this ship until it was reached up to the 6 cm marker of the

beaker. This ship was removed from the water and measured how much weight was used to

cause the “ship” to sink. Sand was put into the cup until the “ship” was submerged into the 6cm

mark. Lastly, the weight of sand was measured.
