In our DEEP experiment, we decided to study Boyle's Law. In order to complete this project, we had to create two experiments, one on land and one in the water. In this analytic essay, we will be analyzing the data of the land experiment. The results of this experiment showed that as the diver's depth increases, the volume of the diver's lungs decreases. But also, if the diver were holding his or her breath, while being supplied with compressed air (when coming to the surface of the water) his or her lungs would expand greatly. This is because as the depth decreases, the volume of the diver's lungs increase. After a short while, the diver's lungs would explode because of its enlarged size, causing fatal injuries.
Because of human error, these projects were not completely correct. For example, in the land experiment we used a pump that had a gauge that measured psi (pressure per square inch). The only problem was that the gauge did not have decimal increments; instead it had increments of 5 psi. This made it difficult to get the precise readings, because of the lack of exactness. We also used a thermometer holder that we had marked ourselves with a ruler, every one centimeter. Because of this, our results were not entirely correct, precise, or exact, which threw us off a little bit. When all of these mistakes were calculated, we determined that the total percentage of error was 10%. Click here to see the graph.
In the water experiment, we used a thermometer holder and we had marked it ourselves with a ruler, every one centimeter. Because of this, our results were not entirely correct, precise, or exact, which threw us off a little bit. These errors made the percent error 12%. Click here to see the graph.
If we were to redesign the land experiment, we would get a pump that had a gauge that had increments of every one tenth. This would help us in many different ways, with one being that our results would most likely be more accurate. Another thing we would probably do is mark the thermometer holder more exactly because this would prevent our results from bring incorrect. This would help us in many different ways, and one being that our results would most likely be more accurate for both experiments.
Our experiment did not exactly follow Boyle's Law. Boyle's Law states that:

Pressure(1)*Volume(1)=Pressure(2)*Volume(2)


When we put our data into this formula, it was not correct. This is because of the error in out experiment.
From these experiments we learned that when scuba diving it is very important to not hold your breath when rising to the surface of the water. During this experiment we learned a new way to stay safe while scuba diving.
