QUESTIONS
1.Does the density of a mineral depend on the size of the mineral sample?

Hypothesis:

It depends on how much air the mineral has inside.   It also depends on the mass divided by volume which equals the density.  To find the density you need to know the mass and volume.

Controlled variables:  How much water is in the graduated cylinder {we will keep this to see the difference between the minerals.} The scale.
Manipulated variables:  The minerals {we will test 3 different kind of minerals so they will have 3 different kind of densities.} 
Responding variables:  Density of the minerals 
Materials:

1. Balance
2. Graduated cylinder
3. Weighting paper
4. Samples of minerals

Procedure: 
1. Choose the 2 minerals, 3 samples each.

• WHITE FELDSPAR
• ORANGE FELDSPAR

2. Find the mass

• 1. orange feldspar 23.6
• 2. orange feldspar 34.3
• 3. orange feldspar 18.6

• 1. white feldspar 32.1
• 2. white feldspar 21
• white feldspar 31.5

3. Find the volume

• 1.orange feldspar 22 ml
• 2.orange feldspar 25 ml
• 3.orange feldspar 14 ml

• 1. white feldspar 28 ml
• 2. white feldspar 12 ml
• 3. white feldspar 20 ml

4. Find the Density
Orange feldspar
1.072
1.3
1.328
White feldspar 
1.146
1.75
1.575

5. Make a table with what the density,volume and mass are



Data analysis 
In the data above i personally can see multiple patterns. The first pattern i see is that the volume is always a little bit smaller then the mass this is maybe because there isn't so much space inside the mineral as much there is mass. The second pattern i see is that there are minerals which have quite the same volume as well as the mass

Conclusion
Does the density of a mineral depend on the size of the mineral sample?  Well from what i have seen in our lab report is that the bigger minerals or the larger ones have more volume and mass then the smaller ones, therefore they it has more density {this is because mass/volume=density.} So I will have to say yes

Further inquiry
If I were to do this whole lab again i would have changed our samples to find a lot of differences in the mass and volume so they would be completely different. I would have also prefered to work in a quite place so i would get distracted. Other then that my group was amazing i could have picked a better group because they started working at once, they didn't argue, and the best of all they were always on track.
