Density Lab
The purpose of this lab was to find the mass, the length, the width and the height of 4 different cubes so we could calculate the volume and density of them. We also had to find the density of irregular shapes by dropping them into a graduated cylinder than subtracting the starting water volume by the ending water volume. Density is how much mass is in a certain volume of matter. Volume is the amount of room that an object takes up. Mass is how much matter is in an object.

My hypothesis is that the mass of the object is going to effect the density and the volume of the object. I also think that the length the width and the height will effect the density.
Materials
-4 cubes (made of unknown material)
-marble
-2 cylinders (made of unknown material)
-rubbing alcohol
-baby oil
-dishwashing liquid
-ruler
-triple beam balance
Part 1 - Density of Regular-Shaped Solids
Step one we used the triple beam balance to find the mass of each cube. Step two we used the ruler to find the length, width, and height of the cube. Step three we multiplied the three measurements to find the volume of all three cubes. Step four we divided the mass by the volume to find the density.

Part 2- Density of Irregular-Shaped Solids
Step one we used the triple beam balance to find the mass of the irregular objects. Step two we found the volume of just the water. Step three we carefully placed one object at a time in the graduated cylinder, found the volume of the water plus the object, which gave us the volume of the object. Step five we divided the mass by the volume to find the density.

Part 3 - Density of Liquids
Step one we found the mass of the graduated cylinder using the triple beam balance. Step two we found the mass of the graduated cylinder and the liquid. Step three we subtracted the mass of only the graduated cylinder from the mass...
