 * Teacher****:** Reminder: Do not use IM Speak. Stay to the topic and you may ask each other questions as well as ask me questions. I will moderate. Make sure to watch for any questions that I pose.
 * Teacher****:** What is density? ...in your own words...
 * Brittany:** how heavy something is. F
 * Alex:** density is the weight of an object F
 * Caroline:** Density is how heavy an object is F
 * Eric:** the weight of an object F
 * Nikki:** Density is the weight of an object. it shows how heavy an object is F
 * Connor:** Density is how compact the atoms of an object are. T
 * David:** Density is how heavy something is F
 * Adrienne:** density is something that stays the same no matter were you are or what the gravity is
 * Cannon:** Density is the weight and how much space it takes up. F
 * Alex:** density x mass= gravity F
 * Teacher****:** So what is mass?
 * Connor:** how much space an object takes up F
 * Brittany:** mass is how much space something takes up F
 * David:** mass is how much space something takes up F
 * Eric:** how much space something takes up F
 * Cannon:** How much space something takes up F
 * Alex:** mass is how much space something takes up F
 * Adrienne:** mass is the amount of space something takes up F
 * Caroline:** how much space an object takes up F
 * Nikki:** the particles in an object that make it up T
 * Eric:** mass is like how much space something takes up F
 * Teacher****:** What is volume?
 * Nikki:** Volume is how much space something takes up T
 * Brittany:** HOW MUCH SPACE AN OBJECT TAKES UP T
 * Teacher****:** Do you want to change your thoughts about what mass is?
 * Adrienne:** voulume = Height x lengh x width T
 * Eric:** Volume is how much space something takes up T
 * Teacher****:** So NOW what do you think mass is?
 * Eric:** mass is how compact it is F
 * Adrienne:** it is how much room is in a three-d object- VOLUME T
 * Alex:** mass is tHE particLEs inside of an object or person T
 * Caroline:** mass is how heavy something is F
 * Eric:** its how much like weight F
 * David:** mass is how heavy something is F
 * Nicole:** Mass is how much room there is inside something.F
 * Nicole:** How many particles are inside something I mean. T
 * Patrick:** Mass is the amount of space an object takes up F
 * Sarah:** Mass is the amount of particles inside something T
 * Nicole:** I know mass doesn't change if the gravity changes which means it has nothing to do with weight.
 * Joshua:** mass is the room or stuff in something F
 * Teacher****:** Can you provide an example of how mass is different than volume?
 * Nicole:** Volume changes on the moon, mass doesn't (NOT NECESSARILY)
 * Nikki:** mass doesn't change, weight changes T
 * Joshua:** no patrick, mass isn't the weight T
 * Patrick:** the mass and weight changes F
 * Patrick:** /but the volume stays the same (MAYBE)
 * Brittany:** no, the weight changes T
 * Brittany:** the mass doesn't T
 * Teacher****:** Hold it....Does mass or weight change on the moon?
 * Marion:** mass does not change on the moon weight does
 * Patrick:** tn define mass
 * Brittany:** Weight
 * David:** weight changes
 * Nicole:** weight changes
 * Brittany:** weight changes
 * Caroline:** weight
 * Eric:** on the moon
 * Marion:** mass is not weight
 * Connor:** weight changes according to gravity
 * Teacher****:** Why does weight change?
 * Patrick:** well weight can change in water too....
 * Joshua:** mass doesn't change, weight changes because of the change of gravity
 * Patrick:** you can float
 * Adrienne:** weight is the only thing that changes with gravity
 * Nikki:** weight changes based on gravity
 * Caroline:** because the force of gravity pull is less
 * Brittany:** because there is less gravity
 * Cannon:** on the moon gravity is decreased
 * Eric:** Less Gravity!!!!!!
 * Nicole:** because weight is the force of gravity pulling on something
 * Nikki:** mass is the stuff (particles) inside of you, so it doesn't change.
 * Teacher****:** Google "mass"- What is it?
 * Brittany:** a body of corent matter, usually of indefinite shape and often of considerable size: a mass of dough.
 * Eric:** it is how much matter is in an object
 * Patrick:** mass is the amount of gravitational pull on an object
 * Nicole:** how much matter is in something
 * Teacher****:** Rephrase inn your own words Brittany...
 * Sarah:** mass is the amount of matter inside something
 * Marion:** mass is the amount of matter in something
 * David:** How much matter there is in an object
 * Patrick:** it is how much matter is in something
 * Joshua:** how much matter in something
 * Patrick:** obvoully
 * Brittany:** The matter in an object......
 * Adrienne:** it is the measure of matter in an object
 * Patrick:** it means everything.....
 * Teacher****:** So if Density = Mass/Volume what does this mean in terms of words...or an explanation of density? Google it and put it in your own words...
 * Caroline:** density is how heavy an object is
 * Eric:** yep
 * Patrick:** density is the how close the molecules are together
 * Sarah:** Density is how much t matter inside something is spread out
 * Eric:** Density is how compact something is
 * Patrick:** in an object
 * David:** How heavy something something is compared their weight
 * Patrick:** object
 * Alex:** density is how heavy a object is compared to its weight
 * Joshua:** density is the difference between two masses and how much volume there is in between them
 * Nicole:** how heavy something is compared to gravity, mass, volume
 * Adrienne:** density is how heavy something is compared to its size.....
 * Sydney:** how heavy something is compared to itself
 * Nicole:** I mean that's what density is.
 * Nikki:** the compact particles inside of something
 * Teacher****:** How about this....Item a and Item b have the same Volume. Items A is more dense than item B. What does this mean in terms of the masses of item A and item b?
 * Caroline:** the particles in the object are more packed together
 * Patrick:** density is how close the molecules together. This proves that density is not mass or weight and is not how close the object is to its weight or how heavy it is or its weight but the structure of the molecules. By doing this you prove what the object can do.
 * Sarah:** Item A has more mass than item b
 * David:** Object A has greater mass
 * Nicole:** It means the mass of Item A is greater than the mass of Item B.
 * Patrick:** item A
 * Joshua:** you multiply to get the same mass of two objects, whichever has less volume has greater density.
 * Teacher****:** Explain....why?
 * Alex:** object a
 * Adrienne:** the particles of item A have more density
 * Cannon:** object A has the greater mass
 * Marion:** Item A has more mass that item B because item A is more dense
 * Nikki:** item a has the greater mass
 * Eric:** i agree!
 * Sydney:** object a
 * Sarah:** A has more because for something to be more dense than something of the same volume they have to have more mass to be more compact
 * Teacher****:** What is buoyancy?
 * Connor:** buoyancy is if something floats
 * Marion:** buoyancy is being able to float
 * Adrienne:** if something floats
 * Joshua:** then you multiply to get the same volume and the more mass on something is denser
 * Eric:** it is something that floats
 * Sydney:** upward force of an object
 * Connor:** the denser the item, it won't float
 * Nicole:** buoyancy is if something floats
 * Teacher****:** What is the density of water?
 * Eric:** to be able to float or rise
 * Cannon:** 1
 * Eric:** floats*
 * Alex:** gram
 * Patrick:** Buoyancy is the upward force on an object
 * Cannon:** 1 g/cm3
 * Sarah:** Buoyancy is the floatingness of an object, if it is less dense than t liquid
 * Alex:** grams per cubic centimeter square
 * Teacher****:** 1 gram/cc or g/mL
 * David:** 1 g
 * Teacher****:** An object sinks in water. What does this mean in terms of its density?
 * Nikki:** that it has a greater density than water
 * Cannon:** the density has to be greater than water
 * Alex:** the object weighs more than 1 gram
 * Connor:** It has a density greater then 1 gram
 * Eric:** it is greater than 1
 * Caroline:** It means that it has more density than water
 * Marion:** this means that the object's density is higher than one gram
 * Sydney:** it has higher density than water
 * Patrick:** 0
 * David:** its density is greater than 1 gram
 * Sarah:** if something sinks in water then it is more dense than water 1g/cm squared
 * Adrienne:** it means that its density is more than 11 gram
 * Sydney:** the waters density
 * Eric:** it is more than 1 gram
 * Adrienne:** *1 gram
 * Brittany:** The water is more dense than the object
 * Patrick:** gas has very high density but does not have a definite shape
 * Nicole:** it has a high density than water, it doesn't float well
 * Joshua:** objects sink if there are more g/cc than the water
 * Patrick:** really???
 * Patrick:** yeah cause t density is so different
 * Eric:** yes
 * Adrienne:** yes!
 * Joshua:** gasoline is less dense than water
 * Caroline:** yes
 * Marion:** yes
 * Teacher****:** gasoline floats on water.... have you ever seen gasoline on the ground at a gas station and it reflects the light like a rainbow...? Why does it float?
 * Alex:** yes
 * Eric:** well
 * Nicole:** I haven't ever seen that
 * Caroline:** it is less dense than water
 * Brittany:** yup.
 * Sarah:** yes it is less dense than water
 * Sydney:** it floats because it has no density...
 * Eric:** because it isn't that dense
 * Patrick:** the density is so different
 * Teacher****:** Could an object have no density?
 * Cannon:** it has a low density
 * Sarah:** no
 * Connor:** its possible...
 * Nicole:** i don't think so
 * Adrienne:** it floats because it has less density than water
 * Marion:** no
 * Caroline:** no
 * David:** no
 * Sydney:** no but it can have very low density
 * Patrick:** in the terms of no density like gas or oil from that matter
 * Alex:** no not really
 * Brittany:** nope
 * Adrienne:** no...
 * Teacher****:** Why can's an object have no density?
 * Eric:** anythings possible
 * Sydney:** because then it can't be an object
 * Patrick:** anything
 * Patrick:** possible
 * Patrick:** i agree
 * Nikki:** it floats because it has a smaller density tn water
 * Nicole:** because it wouldn't exit, without mass and volume it's not an object
 * Alex:** air has mass
 * Adrienne:** because objects have to have mass
 * Patrick:** air has mass but no definite shape
 * Sarah:** all objects have to have both mass and volume and density needs both of those
 * Sydney:** it could be like 0.00000001
 * Teacher****:** An air balloon floats....Why?
 * Sydney:** but not 0.0000000000000
 * Patrick:** thus proved by air contained
 * Alex:** air
 * Eric:** warm air
 * Sydney:** it has air in it
 * Adrienne:** is density affected by how far apart the particles are?
 * Patrick:** air
 * Adrienne:** hot air
 * Sydney:** the air in the balloon is more dense than the air outside
 * Sarah:** when object at of they get less dense
 * Patrick:** it is hot air
 * Sarah:** air balloons have hot air in them
 * Patrick:** why would they have a burner in the balloon anyway
 * Eric:** Its air which is indeed hot
 * Richard:** Hydrogen
 * Caroline:** hot air
 * Patrick:** cause its hot
 * Nicole:** good question, Adrienne
 * Teacher****:** Why would hot air allow a balloon to go into the air?
 * Adrienne:** hot air always rises
 * Patrick:** cough cough
 * Alex:** because hot air floats to t top of everything, houses, cars
 * Sydney:** hot air is more dense than cold air?
 * Sarah:** hot air is less dense than air
 * Richard:** hot air rises
 * Marion:** because it is less dense than normal air
 * Nikki:** at rises
 * Sarah:** hot air rises it is less dense than cold air
 * Cannon:** at rises
 * Patrick:** in at contained in massed amount
 * Patrick:** the particles slow down when they get cold
 * Sarah:** particles move faster when they are hot
 * Richard:** Particles move faster when hotter, and go spread
