Answer 1

# data[].attributes.body
Answer 1 could add in more informations like:
.The height of the metal where it was relesed
.Did the size of the dent change?

Answer 2 can be improve by changing the part more gravitational energy to more gravitational potential energy that will be converted to more kinetic energy and the second part will be less gravitational potential energy that will be converted to less kinetic energy

Answer 3 could be change to:
. more gravitational potetial energy that will be converted to more kinetic energy

Answer 4 could be change to:
. As the height of the drop increases, the depth of the dent will be deeper. ....

# data[].attributes.body
Answer1:i think the answer can be explained further by adding....
-The height of where the metal ball was dropped.
-Does the size of the dent increase or decrease?

Answer 2:I think that the answer is correct but the choice of words and the phrasng is wrong.The answer should add : more gravitational potential energy and it will be converted to more kinetic energy.The next answer should add : less gravitational potential energy thus it will be converted to lesser kinetic energy.
Answer 3:This answer should add that the gravitational potential energy is converted to more kinetic energy.
Answer 4 :This answer is very specific and good however the answer shouyld swap the first sentence and it should be......
As the height of the drop increase,the depth of the dent also increases

# data[].attributes.body
Answer 1: The answer could add in...
-Did the depth of the dent increase?
-How the height which the metal ball drops affects the depth of the dent.
Answer 2: The answer could add in...
-Some words were not use appropriately like 'larger' could be change to 'deeper'.
-What cause the depth of the dent to be deeper other than gravitational potential energy?
Answer 3: The answer could add in...
-"The gravitational potential energy is converted to kinetic energy, thus causing the depth of the dent to be deeper."
-It forgot to add in 'energy' in the last part, "...more gravitational potential energy".
Answer 4: The answer could add in...
-"As the height drop increases, the depth of dent increases".

# data[].attributes.body
Answer 1--> This answer could be improved by adding in...
-How high is the metal ball?
-Will the depth of the dent increase or decrease?
-The energy conversion

Answer 2-->This answer could be improved by changing some of the words in the answer. Examples:
-'larger' (line 2) could be changed to 'deeper'
-'gravitational energy' (line 2) could be changed to 'gravitational potential energy'
-'smaller' (line 4) could be changed to 'less deep
The writer could also include the energy conversion.

Answer 3 --> I think that this answer is not complete.It could be improved by saying this:"As the height of which the metal ball was dropped increase,there would be more gravitational potential energy which would be converted into more kinetic energy. Thus,creating a deeper dent."(bolted-->not mentioned in the answer.)

Answer 4-->I think that there is some error in this answer. Instead of writing ''As the depth of the dent increases, the height of drop also increases" , the writer could have written ''As the height of drop increases,the depth of the dent also increases."  The rest of the answer is fine.

# data[].attributes.body
Answer 1:What does the heights when the ball Is dropped have to do with the depth of the dent.
Answer2: Some of the words used are not very appropriate . You should say that the dent is deeper or shallow.
Answer 3: It should be 'gravitational potential energy' instead of gravitational energy' . The mass of the metal ball doesn't change.
Answer 4: you should have written:As the height of the metal ball drops increases, the depth of dent also increases.Other than that the rest of the answer is fine

# data[].attributes.body
Answer 1: There is no explanation to answer 1 about how it will affect the depth of dent.
Answer 2: The use of word is wrong. Dent is deepness and height can be use like further.
Answer 3: The change variable is not the mass of the ball but the height of which the ball is dropped.
Answer 4: The change variable is the height of the drop of the ball and the measure variable is the depth of dent. Measure variable should be after change variable while not in the opposite.

# data[].attributes.body
1) Could specify how depth of dent changes when the metal ball drops.
2) Some use of words were not the most suitable to describe it, for example, the word "bigger/larger" could have been changed to "deeper/less shallow".
3) The mass of the metal ball remains constant and does not change even by just releasing it from a height.
4) The answer should have been: " As the height, from which the metal ball is dropped, increases, the depth of the dent increases as well.

# data[].attributes.body
Answer 1 could be more specific by stating would the depth of dent would change when the ball drops.
Answer 2 could use other words to describe it
Answer 3 could include if the ball was placed lower or higher

# data[].attributes.body
Answer 1:
It could be improved by being more specific like stating how the height will increase or decrease the depth of the dent.
Answer 2:
It could be improved if some words could be re-phrased such as,
-'Larger' could be changed to 'Deeper'
-'Smaller' could be changed to 'more shallow'
Answer 3:
The mass of the ball cannot change by just dropping it.
Answer 4:
It could be improved by rewriting it like this, ''As the height of the drop increases, the depth of the dent also increases.'' The rest should be fine.

# data[].attributes.body
1. Can be improved by explaining how the height which the metal ball drops from affects the depth of the dent.

2. Some of the words used are not very suitable. It should be that the dent is deeper or shallow. The fact that lesser gravitational potential energy would have been converted to lesser kinetic energy should be included.

3.  The answer was incomplete, in my opinion. It could be improved by saying this:" As the height of which the metal ball was dropped from increased, there would be more gravitational potential energy which would be converted into more kinetic energy, thus creating a deeper dent."

4. The answer was not presented in the right way. It should have been like this: As the height of the ball being dropped from increases, the depth of the dent also increases. All the other part were fine, in my opinion.

# data[].attributes.body
1. Can be improved by stating how the height from which the ball is dropped from affects the depth of the dent made by the ball.
2. The word 'bigger' should be deeper and 'smaller' should be less deep. As stating the different sizes of the dent means that both balls are of different sizes.
3. The mass of the metal ball does not increase when it is dropped. Gravitational potential energy.
4. The higher the ball is dropped from, the deeper the dent. Not the other way around.

# data[].attributes.body
A1) Maybe the person can explain howthe height affects the depth of the dent.
A2) It is detailed, although the deng should be deeper, not bigger.
A3) The mass of the ball is constant, therefore the person can't mention it changing.

A4) the depth of the dent is the measured variable, and it can't change the height of drop.

ANSWER 1: this answer can be improved by being more precise in the answer and by explaining it.

ANSWER 2:This answer can be improved by  giving the prediction.The answer was a relationship-question answer not a prediction.

ANSWER 3:This answer is wrong.The answer stated "As the height of which the metal ball was dropped and the mass of the ball increased,there will be more gravitational potential"
1st mistake in Ans 3:
Mass of the ball increased
2nd mistake in Ans 3:
there will be more gravitational potential _______--> energy?
Mistake 1.According to the question, the mass of the ball did not change.Therefore, he cannot mention that the mass of the ball increased.
Mistake 2.The answer is not complete, the answer should have stated "gravitational potential energy " not just "gravitational potential".

ANSWER 4:I think that the writer could have wrote"As the depth of the dent increases, the height of drop also increases."the writer could have written,"As the height of the metal ball drops increases, the depth of dent also increases."

# data[].attributes.body
Answer 1->It can be improved by explaining:
-The difference when it is dropped from a higher and when it is dropped from a lower height.
-The greater or less amount of different kinds of energy there is.
-The different energy conversions that took place.

Answer 2->It is fine but could add in and change:
-'Gravitational energy' to gravitational potential energy.
-Should have phrased it to describe the question but not phrased it to sound like a relationship question.
-Should have explained about the conversion of energy.
-Could have also changed the words 'smaller' and 'larger' to deeper and shallower.

Answer 3->the answer is not complete and does not sound right.The writer could have:
- Phrased his/her answer in a different way to put out there idea.
-Could have also completed the sentence and not stopping so abruptly by stating that there would be a deeper dent or there would be a shallow dent from dropping it at a lower height.
-The writer should have put 'The depth of the dent will become deeper.' at the end of the sentence instead of at the start.
I would have used the writer's idea and changed the entire sentence into,(If the height of which the metal ball was dropped is higher and the mass of the ball increased, there would be more gravitational  potential energy.The more gravitational potential there is,the deeper the dent would be.)

Answer 4->The way the writer presented his/her answer at the start of their sentence could have been:
-Structured in another way.
-I would have phrased it to,(As the height increases,there would be more gravitational potential energy hence the dent created by the ball would also be deeper.)
-The rest of the writer's answer is good.

# data[].attributes.body
1. He did not state reason
2. There is no such energy as" gravitational energy ". It should be "gravitational potential energy " and instead of using larger and smaller ,use deeper or shallow.
3.HIs answer could be correct if only he did not mention the mass part.
4.He's saying that kinetic energy affects the depth and not gravitational potential energy

# data[].attributes.body
Answer 1 can be improved by explaining how the height which the metal ball drops from affects the depth of dent.

Answer 2 is quite acceptable as it mentions how deep the depth of dent is when the ball is at different heights ( high and low ). However, this answer can be improved further by mentioning that the gravitational potential energy is converted to kinetic energy

Answer 3 should include how the depth of dent becomes deeper--when the  ball is placed at a higher or lower height? It should also include how the ball having more gravitational potential energy affects the depth of dent.

Answer 4 can be improved regarding the first line;
"As the depth of the dent increases, the height of drop also increases."
The depth of the dent does not determine the height of drop, but the other way round. the other parts of the answer on the other hand seem suitable in my opinion as it mentions that more gravitational potential energy is converted to more kinetic energy, which is not mentioned in the other answers

# data[].attributes.body
Answer 1: The answer can be more detailed by adding  this information:Does the dent made by the metal ball become deeper or less deep when the metal ball is dropped from a higher of lower height?If is lower,will the dent made by the metal ball be less deep than to the metal ball that is dropped from a higher height?
Answer 2:The answer is partially correct .The gravitational energy is written wrongly,its is not gravitational energy but gravitational potential energy.The answer also explained quite clear that as the height decrease,there will be less gravitational potential energy.They should also that the gravitational potential energy is converted to kinetic energy.
Answer 3:The mass of the ball remained constant and did not change.It only had more gravitational potential energy.he should also state that the gravitational potential energy is converted to kinetic energy may be more detailed.
Answer 4:Its is very good but there is one point it did not state.They should have also stated how the greater amount if kinetic energy in the metal ball make the dent deeper.

# data[].attributes.body
Answer 1--> This answer could be improved by adding in...
-How high is the metal ball?
-Will the depth of the dent increase or decrease?
-The energy conversion

Answer 2-->This answer could be improved by changing some of the words in the answer. Examples:
-'larger' (line 2) could be changed to 'deeper'
-'gravitational energy' (line 2) could be changed to 'gravitational potential energy'
-'smaller' (line 4) could be changed to 'less deep
The writer could also include the energy conversion.

Answer 3 --> I think that this answer is not complete.It could be improved by saying this:"As the height of which the metal ball was dropped increase,there would be more gravitational potential energy which would be converted into more kinetic energy. Thus,creating a deeper dent."(bolted-->not mentioned in the answer.)

Answer 4-->I think that there is some error in this answer. Instead of writing ''As the depth of the dent increases, the height of drop also increases" , the writer could have written ''As the height of drop increases,the depth of the dent also increases."  The rest of the answer is fine.

# data[].attributes.body
Answer 1 it should be improved by including the height in which the ball is dropped.
Answer 2 the words are not appropriate used as it does not explain the scientific way
Answer 3 it should be written as gravitational potential energy and not gravitational energy
Answer 4 it is very good

# data[].attributes.body
In answer 1, there is no explanation.
In  answer 2, the answer is good but it is gravitational potential energy, not gravitational energy.
Answer 3 is not very good as it did not state when the depth of the dent will become deeper.
Answer 4 is a very good answer as it states everything in a correct way.

# data[].attributes.body
Answer 1: I feel that the answer needs to be a little more detailed, it should include answers to these questions: How high? The higher the deeper dent? The shorter the deeper dent? It should include something about what affects the amount of gravitational potential energy.

Answer 2: The answer is quite good, but some of the words used are not very suitable. You should say that the dent is deeper or the dent is shallow. Maybe include that less gravitational potential energy would have converted to less kinetic energy?

Answer 3: The mass of the ball remained constant, so there may be a little misconception there. Maybe if you wrote, "As the height of which the metal ball was dropped, there was more gravitational potential energy stored in the ball which was then converted to kinetic energy when the ball was released." It may sound better.

Answer 4: It is a very good answer, as it did mention gravitational potential energy being converted to kinetic energy. Maybe saying that the depth of the dent is deeper would sound better.

# data[].attributes.body
Answer 1: This answer can be explained further by adding in this information: What does the heights from which the ball Is dropped have to do with the depth of the dent. Does it make it deeper or less deep? Why is this so?
Answer 2:  From my opinion, this answer is correct but the words used are not appropriate. Instead  of using the word larger, I think that a better word would be deeper. If it is smaller, a better phrase to use is not as deep or less deep.
Answer 3: I think that this answer can be improved . Instead of just saying that the depth of the dent will become deeper( beginning of the answer, the writer should have included when will the depth of dent become deeper. When it is dropped higher or lower? The writer did include  that point towards the end of the answer.

Ban Leng dropped the metal ball from different heights. Predict how the depth  of the dent change with the height of drop. Give a reason for your prediction.

# data[].attributes.body
The height which the metal ball drops from affects the depth of dent.

Please comment on what you think of this answer.

# data[].attributes.body
If the metal ball is dropped higher , the dent made will be larger as it has more gravitational energy. If the metal ball is dropped lower, the dent made will be smaller as it has less gravitational potential energy

Please comment on what you think of this answer.

# data[].attributes.body
The depth of the dent will become deeper. As the height of which the metal ball was dropped and the mass of the ball increased, there will be more gravitational potential

Please comment on what you think of this answer.

# data[].attributes.body
| As the depth of the dent increases, the height of drop also increases. When the ball is dropped from a greater height, there is more gravitational potential energy thus resulting in more kinetic energy. Therefore, the depth of the dent will increase.
