Introduction: For one to learn from this Lab, they must know what density, mass, and volume are and know the comparison to teach other. Mass is the amount of matter in an object and volume is the amount of space that object is occupying. Density is the amount of mass in a given space, which is mathematically defined as mass divided by volume. Problem: How can you use density to determine the identity of materials? Objective: The purpose of this lab is to identify materials using density Hypothesis: In this lab I think we will not be able to accurately calculate the density of given objects do to human error. Even though we will have the proper materials, we will not get the precise answer, but most likely we will be extremely close.

As shown in the data table, we correctly guessed on 62.5% of the objects. This proves that my hypothesis was correct since we used all the proper materials but still came short of a few objects. We were also most likely incorrect because of human error. Some examples are not reading from the bottom of the meniscus or careless mathematical errors. The items that were more difficult to identify were copper, brass, teflon, nylon, and pvc. These items were difficult because either two were very similar, or we had never came into contact with. Copper and Brass felt like doppelgangers because of their similarities and we did not recognize nylon, teflon, and pvc because we did not have much knowledge on them. On the other hand, aluminum, lead, rubber, and glass were very easy to identify because we had previous knowledge on the objects,which helped us identify them just based on
