https://padlet.com/jmessenger/8thGrade Based on the notes given in class today. What did you learn about density? en-us 2017-10-02 18:21:49 UTC 2017-10-12 13:04:11 UTC hello@padlet.com https://padlet.com/jmessenger/8thGrade/wish/193667517 2017-10-03 22:50:01 UTC https://padlet.com/jmessenger/8thGrade/wish/193667517 https://padlet.com/jmessenger/8thGrade/wish/195709482 I learned many things about density in these two videos. For example diet cola will float on water but regular cola will not float.That is because the diet cola has less sugar so the density is less then the water. The regular cola had more sugar then the diet. so it If you split an object in half the density stays the same.  What ever percent is in the water is the density. For example if 75% of the block is in the water the density would be 0.75g/cm3. If the density of wood is less then the water then the wood will float.

What I learned about density is that the density of water is one. If an object placed in water sinks, than it is more dense but if the object floats, than it has less density. I also noticed that in order to calculate density, you must divide mass by volume. ]]> 2017-10-10 16:51:57 UTC https://padlet.com/jmessenger/8thGrade/wish/195709540 https://padlet.com/jmessenger/8thGrade/wish/195709587 Making Sense of density

One thing that I have learned that is if a thing is less than 1 then its density will float. If it is larger than 1 then it will sink down to the ground. ]]> 2017-10-10 16:52:00 UTC https://padlet.com/jmessenger/8thGrade/wish/195709587 https://padlet.com/jmessenger/8thGrade/wish/195709615 I leaned many things about density.....Some things i learned was the formula of density which is Density= Mass/Volume. I also discovered by watch the video links is that more dense objects such as a rock have more mass present in unit volume. Meanwhile in wood there is not as much mass present in unit Volume as the rock. When you have less density than water or air it floats but if you have an object with more density that air or water it will sink. Immiscible liquids are liquids that don't mix. An example of Immiscible liquid is oil and water ]]> 2017-10-10 16:52:02 UTC https://padlet.com/jmessenger/8thGrade/wish/195709615 https://padlet.com/jmessenger/8thGrade/wish/195709745 Making sense of density
I learned that things that are less dense than water suck as wood float, but materials such as rock will sink . you can measure density by looking and measuring how much is below the water then taking that number to find your density. For example: 75% under water is 0.75g/cm3]]> 2017-10-10 16:52:17 UTC https://padlet.com/jmessenger/8thGrade/wish/195709745 https://padlet.com/jmessenger/8thGrade/wish/195709863 Making sense of density                             I learned from the videos that when an object is cut in half the density is still the same. The formula to find density is mass divided by volume. For example wood and oil are less dense than water which is why they float. ]]> 2017-10-10 16:52:25 UTC https://padlet.com/jmessenger/8thGrade/wish/195709863 https://padlet.com/jmessenger/8thGrade/wish/195710016 Making Sense of Density 
I Learned that the formula for density is D=M/V. D is for density. M is for mass. V is for volume. Density is different from mass because mass is what the object weighs with gravity. Density is the amount of substance that is in the object. For example a bag of feather that weighs ]]> 2017-10-10 16:52:38 UTC https://padlet.com/jmessenger/8thGrade/wish/195710016 https://padlet.com/jmessenger/8thGrade/wish/195710322 I learned today that wood floats because it is less dense than water. Another thing I learned is that atoms are a ]]> 2017-10-10 16:53:13 UTC https://padlet.com/jmessenger/8thGrade/wish/195710322 https://padlet.com/jmessenger/8thGrade/wish/195712282 Although two objects may have the same volume they will not have the same mass. Density=Mass/Volume. Density is the amount of mass relative to being in the amount of volume. A large piece of wood will float but not a small rock. The reason being because the water the wood floats on is more dense than the wood which is less dense.]]> 2017-10-10 16:56:21 UTC https://padlet.com/jmessenger/8thGrade/wish/195712282 2018aburks https://padlet.com/jmessenger/8thGrade/wish/195842203 I now know that what ever has a greater density will sink and what ever has a lower density will float. The object with a greater density will sink because it has a greater density than the water that it is placed in. Take a rock for instance, it will sink because it has a much greater density. Now, if you place a large piece of wood into water it will float because it has less density than the water. ]]> 2017-10-10 23:54:42 UTC https://padlet.com/jmessenger/8thGrade/wish/195842203 2018jkeller https://padlet.com/jmessenger/8thGrade/wish/195844825 Making sense of density
I learned that the formula for density is D=M/V. Density is different from mass because mass is the weight depending on the gravity but density is the amount of material in the object. I also learned that if you cut and object in half it will have the same density. the last thing I learned was that if you put an object with less density in the water it will float. If you put an object with a higher density in the water it will sink. ]]> 2017-10-11 00:20:01 UTC https://padlet.com/jmessenger/8thGrade/wish/195844825
