Name of Grader:
If different objects of same mass are placed in water; their positions in water vary depending on their sizes, the big objects will go deeper into the water than the smaller objects.
Part 2 Hypothesis:
If objects have different mass but equal volume, the objects with small mass have the least density as compared to objects with bigger mass.
If the material of an object is unknown, it can be determined by obtaining the density of the material and matching them with known material densities to identify the material of the object.
Part 1: How does volume affect density?
I first obtained the blocks of similar masses and then immersed each block, one by one, into the water while observing and noting their positions in the water.
Part 2: How does mass affect density?
I first obtained blocks of the same volume, from which I noticed the blocks had different masses. Secondly, I placed the yellow block in water and recorded what happened. I then removed the yellow block from the water and placed the red block in water and also recorded what happened.
Part 3: Finding the density of Various Objects
After obtaining various objects from the “mystery” options. I measured the weights of each block and recorded them. After obtaining the masses of all the blocks, starting with block A, I placed block A in water and recorded the new position of the water level. I then removed block A from the water. I also took block B of known mass and placed in water. Block B, however, did not fully risk into the water. I dragged it down to obtain full volume and recorded the position of water. I repeated the same processes with the remaining blocks as I recorded their new position in the water. All the blocks that did not sink fully into the water were pulled down in an attempt to obtain accurate measurements of their volume and not just the parts under water.
Part 1: Same Mass, Different Volume
What observations do you have about the comparative volumes of the 5.00 kg blocks?
The comparative volumes of 5.00 kg had different volumes. The yellow block had the biggest volume, followed by the blue, green, and red block.
What happened to each block when you placed them in the water, where did they end up in the water column?
When the blocks of 5.00 kg of different volumes were each placed into the water. The smallest blocks, both red and green, sunk to the bottom surface of the water. The blue block, which is second largest, only sunk halfway but fully into the water. The yellow and biggest block was not fully into the water as only some parts of it were under the water.
Part 2: Same Volume, Different Mass
What happened to the volume of water when you put the yellow block in the water?
The volume of water increased to 105 L
Show how you would find the volume of the yellow block.
Volume of yellow block=Volume of water with the yellow block-volume of water without the yellow block
What is the volume of the water when you first put the red block in the water?
What did you have to do to make the water read the same volume with the red block as it did with the yellow block?
The red block did not fully go under the water. To make the volume the red block equal to the yellow block, I had to pull the block to ensure it was fully under the water.
Part 3: Obtaining Density and Determining Material
Name of Block
Data Analysis- Calculations:
Name of Block
65.14 kg103.38-100 L
Data Analysis- Interpretation Questions:
* Answer all questions listed below
Each block for part 1 was in a different part of the water column, what does their position in the water column say about the density of each block? How can you tell which is the least dense or the most dense based on where it was in the water?
The positions of water columns for the blocks in part 1 varied depending on the volume of the blocks.
Based on their positions in the water, the smallest blocks have the highest densities, followed by the blue block, and then the yellow block, which has the lowest density.
For Part 1, you just changed the volume. What is the relationship between volume and density?
An increase in volume leads to a decrease in the density, while a decrease in volume leads to an increase in density.
For part 2, you just changed the mass. What is the relationship between mass and density?
Density increases with an increase in mass
Describe how you found the volume of each block in Part 3.
Volume of each block was given by water level when the block is fully under water-water level without any block.
The change in volume of water/level of water represented the volume of the blocks.
