I chose c because (1)flying vehicles will land without engines or hot air propeling them up(this disproves a and b) and (2)no thrust is needed to make a plane land,just gravity.However if a plane where to be high enough,And it flew side ways it would fall but it would be moving forward to so it would orbit the earth even if the thrust was turned of because there would be almost no friction with air to slow it down.Therefore it is possible for b to work.But near earth objects (planes) will fall to earth.

I chose C because 1 planes and baloons can land so it cant be A also if gravityis too weak some larger things like big cars and other objects would flooat into space so it cant be B so that leaves only C and thats the answer

I chose letter C because letter b says that gravity is too small so that is elimanated . Then I looked at A It said gravity dosen't exist . That was defintly wrong . So student c was correct plus they said that gravity is always present wich is true

I chose student c because he provided more scientific information than the other students because the other students did not provide as much information. For example, student a said that there is no gravity and that is not realistic because if a train was going at top speed it would not be flying.

I chose Student C because of process of elimination. Student A is not correct because gravity is always present according to scientific facts. How do you think elephants stay on the ground? Student B is not correct because there are things bigger than a airplane/hot air balloon, such as a roller coaster or a mansion. So, Student C is correct.

Why I chose that student is that Student C is saying exactly what the picture describes. Anyways, it makes sense, but Students A and B don't make sense at all. Gravity does exist. Student A says that some things do not always stay on the ground and that is not right. The airplane on the left column has engines, which help it fly. The hot air balloon on the right column is filled with hot air, which makes it float. Student B says gravity is too weak to pull down the airplane or the hot air balloon. So that is the reason why I chose Student C.

I agree with student C because student A said that there is no gravity but there is so student A was not an option. Student B said that gravity is too small to affect the items so that did not make sense and thats not true so the last answer made the most sense so i picked that one.

I choese stutent C because all of the thing would be flying

I picked student c cus he put down more detail and evidence in in his writing then the others. For example student A put that gravity does not exist that makes no sense cus then that plane would have been floating not moving forward. so what i'm saying is gravity does exist.

I chose student c because, Obviously, gravity DOES exist. If gravity did not exist the sun would become a black hole and then explode for black holes are pure gravity. And if heavy objects escaped gravity then the sun would wonder off and so would the earth, plus the earth would and everything els, would implode.

I chose Student C because it makes the most sense and the other options are not as reasonable. Student A's response was incorrect because because Gravity does exist, Student B's response is saying that gravity is to small to pull down those big objects. Student C's is the most reasonable.

Lily

lilym4121 — 2018-01-18 21:07:23 UTC

I think it is student C. Student A is incorrect because gravity does exsist. Student B is incorrect because gravity would be strong enough to pull them down. It is true however, that the items stay up because they have wings, hot air, or other forces. Student C is correct in my opinion.

I chose Student C because it is true that gravity is always present on Earth. This can be proven by the fact that all objects fall to the ground when let go in midair. Student A says that gravity does not exist. Student B says the gravity on Earth is too small to affect these items, but if an airplane stopped functioning, for example, it would also drop.

The reason that I agree with Student C is because I believe that gravity does exist. I think this because when you are on Earth, you stay on the platform that you are on and when astronauts go to outer space, the float and thats another reason that they have seatbelts in rockets. And the reasons I didn't agree with Students B or A

I chose Student C becuase what Student C says is true and I also chose Student 3 becuase Student C has the most understandable.

I think student C is correct because the speed,force,and stability of these objects compete greatly against the gravity of the earth and it overpowers that gravity, allowing it to fly.

I chose student "c" not because other people chose it but because its the only one that makes actuall sense. Like who would answer with this, "Gravity does not exist. These objects prove that things do not aways remain on the ground." Or "Gravity is a force that pulls things down to earth. The gravity on earth is to small to pull big these down such as these." Its only c that makes sense. Student a and student b are wayyyyy incorrect. If gravity does not exist, then we would be floating right now. And student b says that big things float... or that he or she beleives in gravity but then again he or she doesnt. Student c is the only correct student. They are saying that there is always gravity on earth and that things such as airplanes hot air balloons and other flying abjects are either using wind power or heat.

I choose this because this is the smartest answer and also, becausei in my opinion the other students only give one reason.Another reason is :That if there was no gravitiy then the objects on the ground would not be standing they would be floating .

I chose student c because he makes the most sense and he is right about it.

Reina

reinal7033 — 2018-01-18 21:07:58 UTC

I think it is Student C because gravity can't just turn off it is always there. Then we would be floating around like in space.

Zyair

zyaird6985 — 2018-01-18 21:08:04 UTC

Student c because he make the most sense and the hot air lifts the ballon

Vincent

2018-01-18 21:08:06 UTC

I chose him because he is giving examples that are correctunlike a&b

Eden

edenw7025 — 2018-01-18 21:08:09 UTC

Why i chose answer c was because the boy/girl was right if gravity was not on earth we would all float and sooner or later we would go into space and since we would not have oxegen from earth we would not be alive any more.

Andy G

andrewg4125 — 2018-01-18 21:08:14 UTC

I must agree with student C beacause his/her explanation is most lodgical, student B's response was almost right, but the bigger the item, the heaver the item. Student A's response was just un-exeptibal!!!

Callianne #29

callianner6002 — 2018-01-18 21:08:16 UTC

I chose student C because i think student A and B are incorrect cause student A says gravity doesn't exist and that not true cause when we jumpwe dont go up we go straight down and things dont float

Zach

zacharys6483 — 2018-01-18 21:08:30 UTC

I think that student c is right because student b is applying that there is gravity in space which is wrong and also student a said gravity does not exist which is wrong because how come when we jump we fall back down.

Michael #25

michaeln6206 — 2018-01-18 21:08:32 UTC

I think that c is correct because A says that gravity does not exist and that is incorrect. Also on B it says that gravity on earth in too small and that is also incorrect.

Brady

bradyh3407 — 2018-01-18 21:08:39 UTC

I chous c becous he is tru the fire dous lift the buloon and the plane has big jets that make it go in the air.

Yuliana#21

yulianam6221 — 2018-01-18 21:08:40 UTC

I choose student c student a is not correct because gravity does exist because to prove that gravity exists why are pencils on our desks why are we not in the air

khalilk6033 — 2018-01-18 21:08:42 UTC

I think its student c because things such as airplanes and hot air balloons have wings and hotair that lets them fly

Noah C

noahc5910 — 2018-01-18 21:09:16 UTC

I think it is student c because the fire increases the heat witch makes go up

jenniferk5978 — 2018-01-18 21:09:54 UTC

Jennifer

I chose student C because it makes a lot of sense that with gravity you will be able to jump out of a air balloon.

Jimmy

2018-01-18 21:14:04 UTC

I think this because the earth's gravity is not strong enough or stops competing with these objects with a certain height or with certain circumstances that allow these items to not be pulled down by gravity as fast/not being pulled down at all.

I think its c because air planes and hot air let them go up like the planes wings let it fly up amd with no garvity we whould go up
