Density Simulation

               Some things I discovered about density are. To find the density you have to take the mass divided by volume which will equal the density. The volume is the surface area, and the mass is how tightly spaced the molecules in the shape. In the sixth grade we did an experiment with pop cans and blocks of wood. We had to guess which ones would float and which ones would sink. We were all assigned a piece of wood. We had to guess what its density would be. He also had us practice how to find density.

Density Simulation

        The more density something has the easer it will float. If you have more less density than mass the object will float. The formula for density is mass/volume that will equal your density. You can not tell if something the same size  is going to sink or float because they could have different density.

Density Simulation

Do you often wonder what density is? Density is how compacted or smushed together and object is. The formula density is: mass divided by volume = density. Volume and mass also contribute to density. Mass is the amount of matter in an object and volume is how much matter an object holds or can hold. This is what I have learned about density through the simulation.

Density Simulation

On Friday after our test, our teacher found a mass and volume simulation.  They had different materials like wood, ice, aluminum and steel.  We found out that when you have high density and small mass then whatever it is would sink.  But a high mass and low density than it would float.  The aluminum and steel always sank which wasn't a surprise.  The thing that I understood was that it doesn't matter how big something is but how dense it is.

Density

  Density is a measure of how much mass is contained in a given unit volume. If two objects are the same mass and get put into a tub of water with different volumes, the one with a bigger volume will float and the one that has a smaller volume will sink. 

Density Simulation

Density is the amount of mass in a given volume. If two objects have different mass but have the same density, they will both have the same effect when placed in water. If two objects have the same volume but different masses then the one with the most mass will go the deepest in the water. If I had to explain density in my own words, it would be how much mass is in an object that affect its weight and buoyancy. The mass to volume ratio is what causes an object to sink or float.

Density Simulation

A high amount of mass causes a block to sink even if there is a lot of volume or even a little. If there is a lot of volume and a lot of mass it will sink, but if it has low mass it will float.

Density Simulation

If you have lots of mass then it will float. If you have the same mass but smaller they will sink and the biggest will float.

Density Simulation

Last Friday we went online and experimented with different types of blocks and water. When put in water styrofoam floats on the top of the water, no matter what it’s mass or volume is. When wood was put into the water it floated at it’s smallest mass/volume, but as the volume/mass got bigger the bottom got deeper in the water. An ice block was put into the water and it floated just below the surface of the water, no matter what mass/volume it had. Brick always sinks to the bottom. Also, aluminum always sinks to the bottom. I have noticed that the bigger the volume the more the water level goes up, the smaller the volume, and the water goes down. Volume usually did not affect how much the block sunk or rised. 

Density Simulation

The blocks with the same mass sank but the bigger block did not. The same density blocks all floated. The Same density will float the same because it has the same density. The size matters little but the volume will tell you if it floats. Mass devided by Volume = Density.

Density Simulation~

When I was messing with the density site I noticed some interesting things. If you have a block of wood that is one cubic foot and another block that is one cubic inch that does not necessarily mean the bigger one is going to sink. Which ever one's molecules are the closest together or which ever one has the most density is the one thats going to sink. So that means you can't tell if something is going to float or sink by its size.

density simulation

I figured out a lot of things from the simulation. One thing I found out is that if a lot blocks have the same density, they all float. If the volume or mass is the same, but density is different, the outcomes after being put in the water will be different.

Density Simulation

In the Density Simulation, there were five different materials. At wood's minimum density and volume, it was a third under water. And at the maximum, it was a little over a third under water. With Styrofoam, at 1kg, it was a little under an eight, but when it was 3kg, it was a little over 1/8. With ice, at its minimum, it was 8/9 under water and at its maximum, it was still 8/9 under water. But with Brick and Aluminum, they both were sunk at their minimum, and still sunk at its maximum. But with some materials, the bigger the mass and volume get, the more it floats. But with some materials, the larger they get, the more they sink and the larger the material is. That is my Density Simulation Blog Post.
