https://padlet.com/jmessenger/Grade8 Based on the notes given in class. What did you learn about density? en-us 2017-10-02 18:18:31 UTC 2017-10-13 13:19:44 UTC hello@padlet.com https://padlet.com/jmessenger/Grade8/wish/195597245 Making Sense of density

I learned that density relates the mass of a materiel in a given volume. To find density you divide the mass by the volume. If you want to know if something is more dense or less dense than water than put it on water and see if it floats. If it floats than it is less dense than water if it sinks than it would be more dense than water. If you put a log on water it will float because it is less dense than water. If you were to put a small rocks it would sink cause it is more dense than water.

Some things that I have learned about density is that objects with a density greater than one will sink. Also that density is the measure of mass. For example, a lodge of wood has less mass present in unit volume, while water has more mass present in unit volume. Oil has less density than water that is why it floats. You can calculate density by mass divided by volume.]]> 2017-10-10 13:54:47 UTC https://padlet.com/jmessenger/Grade8/wish/195598121 https://padlet.com/jmessenger/Grade8/wish/195599783 Making Sense of Density

I learned that if an object sinks, it has more density than water. If an object floats, it has less density than water. An example of this could be when oil spills in water, it floats because it is a lot less dense. I also learned that you can measure  an objects density by how much water it is displacing. ]]> 2017-10-10 13:57:35 UTC https://padlet.com/jmessenger/Grade8/wish/195599783 https://padlet.com/jmessenger/Grade8/wish/195600406 Making Sense of Density

I learned many things about density in this chapter. First off, I learned that density relates the mass of a material in a given volume.]]> 2017-10-10 13:58:40 UTC https://padlet.com/jmessenger/Grade8/wish/195600406 https://padlet.com/jmessenger/Grade8/wish/195600407 Scientists use density to measure things, because it does not change with location like weight. Density can be calculated by using the formula mass/volume. A great example of this is when we put a block of wood into the water and it floats, but when we put a block of steel it sinks because the density is higher than the water.  Based on the notes given in class I can conclude that if you put an object  that has a higher density than water it will sink when it is placed in water.  I also learned a lot of Archimedes principle. Archimedes Principle states that if an object displaces an amount of water that weighs as much as or more than the object, the object will float. Also there is a force called the upward force, A.K.A the buoyant force that opposes the downward force of gravity.

I learned a lot throughout this chapter and the labs. I learned that density is the measurement of mass in a given volume. I learned that in order to find the density of and object, you have to divide the mass by the volume. I also learned that if you place and object like wood in water and it floats, that means the object is less dense than water. If you place an object like a rock in water and it sinks, that means that the object is denser than water.  The same thing goes with air. The reason why a balloon filled with helium floats, is because helium gas is less dense then air. Another thing I learned is if and object has a density that is less than 1g, it will float. If the object has a density higher then 1g, it will sink. I also learned that two things that look exactly the same could be different densities. Like a Coke and a Diet Coke look the same, but the regular Coke has a higher density. This is because a Diet Coke doesn't have any sugar, but a regular Coke does. ]]> 2017-10-10 20:06:17 UTC https://padlet.com/jmessenger/Grade8/wish/195805108 2018aellerman https://padlet.com/jmessenger/Grade8/wish/195810340 I learned through this chapter and the labs.

I learned that if a objects density is less then 1 the object floats and if the objects density is more then 1 it sinks]]> 2017-10-10 20:24:27 UTC https://padlet.com/jmessenger/Grade8/wish/195810340 https://padlet.com/jmessenger/Grade8/wish/195814494 Making Sense of Density

I learned many things about density in this chapter. First off, I learned that density relates the mass of a material in a given volume. Density can be calculated by dividing mass by the volume. If an object is less dense than water it will float, and if it is more dense than water it will sink. An example of this is when wood is put in water, it floats because wood is less dense than water, and when an object such as a rock is put in water, it sinks because the rock is more dense than water. You can tell the the density of the object by the amount of water that the object displaced.]]> 2017-10-10 20:40:26 UTC https://padlet.com/jmessenger/Grade8/wish/195814494 https://padlet.com/jmessenger/Grade8/wish/195817321 The things I learned about density were that density relates to the mass of a material in a given volume. I also learned that it's a physical property of substances. When you put an object in water you can find out the objects density by looking to see if it floats or sinks. If the object floats it has less density than the water, but if it sinks that means the object is more dense than the water. I learned that when you put oil in water the oil doesn't mix with the water. Instead, I learned that the oil is separated in the water by the oil having more density sinking to the bottom of whatever container you have your water in. In the section about density I learned the formula for it (D=M/V). I also learned that the density of the object depends on the build up on its atoms.]]> 2017-10-10 20:55:59 UTC https://padlet.com/jmessenger/Grade8/wish/195817321 https://padlet.com/jmessenger/Grade8/wish/195829992 I learned many things about density in this unit. The first thing I learned in this unit is the defintion of density. Density is the measurment of how much mass of a substance is contained in a given volume. You can do many experiments to observe matter. The first experiment you can conduct is uses two coke bottles, one diet coke bottle and one regular coke. If you put the two cokes in the water the diet coke will sink and the regular coke will float. The reason for this is because the diet coke is denser then the water. You do not have to do this experiment with cokes you can do it with any objects. Density also relates to the mass of a material in a given volume. Often density is expressed as the number of grams in one cubic centimeter.  Density is also a physical property of a substance. So, density can be used to identify an unknown substance. ]]> 2017-10-10 22:15:58 UTC https://padlet.com/jmessenger/Grade8/wish/195829992 https://padlet.com/jmessenger/Grade8/wish/195831121  Making Sense of density

If you were to put a small rocks it would sink cause it is more dense than water. Another example is if you have a diet coke and a regular coke then one of them will float and one will sink this is because of density. the diet coke will float and the regular coke will sink. The reason why the diet coke will float is because there is no sugar and the sugar in the regular coke makes more atoms to where there is more density. This is what i learned about Density.  ]]> 2017-10-10 22:22:49 UTC https://padlet.com/jmessenger/Grade8/wish/195831121 https://padlet.com/jmessenger/Grade8/wish/195833125 Making Sense Of Density Pt 2 

If an object floats it will most likely have less density than water. If someone were to put a stone in water it would sink. Also for example if you placed a piece of cardboard it will float, this happens because of the density in each material.

In this section I learned that if an object is less dense, it will float in water. If an object is more dense, it will sink in water. A large piece of wood will float in water because it has less density than the small rock which is higher in density. ]]> 2017-10-11 11:01:01 UTC https://padlet.com/jmessenger/Grade8/wish/195957938 https://padlet.com/jmessenger/Grade8/wish/196226415 Density is the measurement of how much mass of a substance is contained in a given volume.  The first experiment you can do is use two coke cans, one diet coke and one regular coke.  If you put the two cokes in the water the diet coke will sink and the regular coke will float.   It float because the diet coke is less dense than water.  Density has to do with the mass of a material in a given volume.  The expression for density is in gram in one cubic centimeter.]]> 2017-10-11 21:22:19 UTC https://padlet.com/jmessenger/Grade8/wish/196226415 https://padlet.com/jmessenger/Grade8/wish/196651209 I learned that Density is the measure of the mass of an object per unit volume. The formula for finding density is mass divided by volume. An example of density is that when an object has less density then water the object will sink. If the object has a bigger density than the water the object will sink. One thing I didn't know was that if the density of an object is really high but smaller then the water's density the object will barley float. But if the object's density is really low then the water's density the object will float easily. ]]> 2017-10-12 22:18:46 UTC https://padlet.com/jmessenger/Grade8/wish/196651209
