Christina (TL) Ruchi Joseph P.

-Materials and Methods:
Materials: - 10 cubes of different material - Scales - Magnet - Ruler - Tablet

Methods: 1. Take the first cube and put it on the scale 2. Write down the the mass of the cube in grams 3. Find the volume of the cube by measuring Length x Width x Height 4. Once you have found both the mass and the volume, do mass/volume 5. Once you find the density, put it in the table 6. Repeat this process for all of the cubes

-Analysis
The way that we came up with what we have is that we took its qualitative data. We knew that something like aluminum would be silver and heavy. For some of the cubes you could obviously tell what the were. We were able to narrow the search down easily for others because it is easy to tell what is wood and what is not. A bunch of web site helped us out as well because we could tell if one of our cubes looked like what was described on the web site then it was probably that material. That is how we went about finding the material of the cubes.
