How do you calculate Density?
What units did you use for volume, mass, and density?
When the cubes are placed in water which one will sink 1st?
What is the ranking of the cubes lightest (1) to heaviest (10)? Is it true that the cube with the most mass will have the most density?
I think the 1st cube was aluminum
I think the 2nd cube was steel
I think the 3rd cube was brass
I think the 4th cube was copper
I think the 5th cube was acrylic
I think the 6th cube was oak
I think the 7th cube was pvc
I think the 8th cube was pine
I think the 9th cube was poplar
I think the 10th cube was nylon
Triple beam balance
1) Thought of my hypothesis when Mrs.K was showing us the cubes. 2)I used a ruler to calculate the volume of the cubes in cm3 3)I used a Triple beam balance to calculate the mass in g
4)I divided the mass by the volume to get the density in g/cm3 5)I ranked the cubes from lightest (1) to heaviest (10)
6)I repeated these steps for each cube.

I thought the 1st block was aluminum, I was right.
I thought the 2nd block was steel, I was right.
I thought the 3rd cube was brass, I was right.
I thought the 4th cube was copper, I was right.
I thought the 5th cube was acrylic, I was wrong, it really was nylon. I thought the 6th cube was pine, I was wrong, it...
