According to the definition Density is the physical property that allows us to compare the mass of substances for a specific volume. In this Lab activity that took place in Deree College, Agia Paraskevi Campus we deal with the density of solids and density of liquids. The main purpose of this experiment is to understand what in reality density means, how we can measure it, how useful it is, what is the difference between density of solids and liquids, if the measurements that we did are been accurate and how we can calculate the percentage errors.


- 3 different metals
A) copper
B) iron
C) aluminum
- 3 Different liquids
A) Water
B) Olive oil
C) Alcohol
- Balance
- Cylinders of 25ml, 100ml
- Calculator


In this Lab activity we saw the differences between the density of solids and the density of liquids.

Firstly we obtained three different solids a piece of aluminum, a piece of copper and a piece of iron, and we measured their masses by using the balance. Also, we measured their volume by using a cylinder with distilled water, then we have measured the volume, and then we put in the metal and recorded the total volumes. After that we calculated each density and we recorded the average density (by classmates). Also, I found the literature density through a web search. Finally we calculated the percentage error by using the following formula: (Density from data – Density from literature) / Density from literature * 100

The results are shown in the following table:
|MASS OF SOLID |47.5 |160 |143.5 |
