Lab Report
This lab was to see does the weight of a mineral affect the density of it
My class and I had to pair up or be in groups, I was in the group with Miona and Sofia. Procedure was First to get all of the materials which were a balance scale, 3 different types of rocks, a graduate cylinder filled with water up to 150 milliliters. That is the volume of the mineral. After that we divided the mass by the volume to get the density. And then we do the same thing for every other big and small mineral.
Materials:
Balance scale
Graduate cylinder (filled with water)
3 different types of minerals
Procedure:
Measure each mineral and record its weight
Dip the mineral in the graduate cylinder which is filled with water up to 150 mm
Record for how much did the mineral rose up the water in the graduate cylinder
Observe does the weight affect the density of a mineral
Divide the centimeters of the rose water
Procedure:
First we need to measure the weight of the mineral on a balance scale to figure out the mass of the mineral. afterward we need to fill a graduated cylinder with water up to 150ml. subsequently we put the mineral in side and see up to where the water rises, that is the volume of the mineral. following that we divided the mass by the volume to get the density. And then we do the same thing for every other big and small mineral.
Hypothesis:
Q: Does the weight of a mineral its density
A: Yes, if the mineral is heavy the more is the density with it.
Controlled, Manipulated, Responding Variable
While testing and observing the minerals we have learned that there are controlled, manipulated, and responding variables’, the controlled variable is the one that could be controlled in other words means that the substance did not change and was controlled, manipulated variable is the variable which could be changed in other words the substance can or could be changed, and the responding variable is when it is changed the change can make another substance so it can respond. In this case we observed 3 minerals which were pyrite, sulfur, and azurite.
• Controlled (the same): water
• Manipulated (change): samples (Sulfur, Pyrite and Azurite)
• Responding: Density
Procedure:
First we had to weight the mineral and see what was its weight, afterwards we have put the mineral in the graduate cylinder which was filled with water up to 150 milliliters, when we would drop the mineral in the graduate cylinder we would see for how much did the water raise up.
The data table
Mineral Size Mass Volume Density
Sulfur big 28 180 1.55
Sulfur small 14.3 160 0.09
pyrite Big 41.5 165 0.25
pyrite Small 29.7 160 0.18
Azurite Big 60.6 170 0.36
Azurite Small 0.71 150 0.0047
Graph
Data Analysis
As I can see from my graph, that the weight does effect the density of a rock. In my graph it indicates that the lighter the mineral the less it roses up water, I also notice that sulfur lifted the water surface, and with the purpose of pyrite and azurite are pretty much the same. In weight the heaviest of most was azurite which was 41.5, the second was sulfur which was 31.3, and the lightest was pyrite which was 16.6. From this lab I have learned that just how much mass does the mineral have it means that its density will be as its mass.Sulfurs density was 2.07 g/cm3 density was (Electron Density)=4.84 gm/cc note. and Azurite density was Average = 3.83
Further inquiry
While doing this lab we had made some errors, like: we had a hard time getting all of our materials, and getting along in the group, and measuring the minerals correctly. If I was to do this lab again I would improve in these three areas along with my group. We have afterwards excelled in cooperation in our group, which we collected information together and did our jobs in the group.
Conclusion:
From this lab I can conclude that if a mineral has a large weight (much mass) its density will be also high. From this lab I have learned a lot of things but this one was the main one. I also learned how to measure the density of a mineral, which is you need to have a graduate cylinder filled up with water up to 150 ml and drop the mineral inside of the graduate cylinder and see for how much did the water surface raise. up the more it rose up that’s the more it has mass inside it. So I think I have learned from this lab a great deal.
