Fine. I have seen some students who have responded over the weekend, so please check the web whenever you can. Also, when you respond, can you please write "DR. BOWERS--- PLEAS CHECK-- FIRST RESPONSE" This will ensure that I read it as soon as possible so that you can get it out to the student as soon as possible. The system does not distinguish between first and second responses when it emails me, so this is the only "fix" that I can use to get around the bug. Thank you,

Student's Name: John Answer(or question to Mentor): I think his house did get washed away because more of the pole was stuck into the ground which would make his pole shorter and it would wash away.

Hi John, thank you for submiting an answer.
To start the probelm, consider that in 2000 the storm surge covered 1/3 of the stilt leaving 5 feet (2/3 of the stilt) dry.
I am looking forward to reading your response.

Student's Name: John Instructor Comments: Lillian,
Given that John did submit a response, you need to be upfront and specific in saying that his answer is incorrect. Actually, I am not sure if he was responding to the original problem, or the challenge problem! At any rate, please include the following in your response:
1. Thank him for submitting, but state that he has not gotten the correct answer. Then explain that he needs to explain how he arrived at his answer so that you can help find out how he was thinking about the problem.
2. In a new paragraph, include your sentence about how to start the problem (but fix the typo in probelm)
3. Add more to the description of what he needs to do. Specificity will help. State for exmaple, that he can use that information to find out how high the storm surged in 2002, and how many feet were left dry. Then remind him that he can use that information to answer the challenge question as well. Dr. Bowers

Student's Name: John Mentor Reply: Hi John, thank you for submitting an answer.
However, your answer is incorrect. Can you explain how you arrived at this answer?
To start the problem, consider that in 2000 the storm surge covered 1/3 of the stilt leaving 5 feet (2/3 of the stilt) dry. You will use this information to find out how high the storm surged in 2002 and how many feet were left dry.
The information used to solve this week's problem will help you answer the challenge problem. I will be looking forward to reading your response.

Student's Name: John Answer(or question to Mentor): Well I just thought if his pole was shorter that it would have an effect on the reason why his house did get washed away or not. I thought if the pole was shorter than the storm surge would reach the house and take it away. because if the pole is dug into the ground the house would be lower. But now since I am wrong I have a diffrent hypothises it is that if the pole is stuck into the ground more it could be stronger than having more pole exposed to the storm. I am sorry I did not respond on the given date. Bye.

Student's Name: John Answer(or question to Mentor): The pole has to ten feet and that bobs house did not get washed away. It did not get washed away by .375 feet. I figured this out by finding out how many feet the pole was. The pole is ten feet tall. In 2002 Andy had 3/4 of his pole covered and his pole was 7.5 feet out of the ground. The storm surge in 2002 is 7.5 feet times 75% or 5.625 feet. Bob pole sticks ou of the ground by six feet so the storm surge is smaller and Bobs house is saved.

Student's Name: John Mentor Reply: Hi John, you did a great job in determining that the stilt is 10 feet high.
Your answer, 5.625 feet, to the first question is correct.
The answer to the second question is 1.875 feet. To get this answer, you subtract 5.625 feet (height of 2002 storm surge) from 7.5 feet (height of stilt out of the ground).
Your answer to the challenge problem is correct. Bob’s house did not get washed away because the storm surge is 0.375 feet lower than the stilt.
Thank you for attempting this problem and for your great effort.

Student's Name: John Answer(or question to Mentor): Charels cheesburger has 270 calories. I found that out by sayin 9 times 14 which would give you 126, 36 times 4 which would be 144 and 15 times 4 and that would give you 60 and when you add all that up you get 270 calories. The percent of calories ingested was 13.5 percent and I got that by dividing 270 divided by 2000 which gave me .135 and then I multiplyed .135 times 100 and got 13.5. On the last part I got 21.5 percent of the burger was fat. I got that by adding 14 grams of fat 36 grams of carbohydrates and 15 grams of protein and that gave me 65 grams. Then I divided 14 grams of fat by 65 total grams and that got me 21.5 percent. For the challenge problem my answer was 36 chicken nuggets I found that out by working guesing a number that 3 would go into evenly and just work from there. So I said 1/3 of 36 was 24 and then 3/4 of 24 was 6 and 1/2 of six was 3 and that wal the total number of chicken nuggets left over.

Student's Name: John Mentor Reply: Hi John, thank you for submitting an answer. Your answer to the first problem of 270 is incorrect, but you were on the right track. Your conversion from grams to calories is correct; however, your final addition step is incorrect. Therefore, your percentage of 13.5% is incorrect.
For question two your answer of 21.5% is incorrect. Can you please explain why you added 14, 36, and 15? Hint: The question asks how many fat calories are in a single cheeseburger.
Your answer to the challenge problem of 36 chicken nuggets is correct. I do realize that you guessed and checked. Suppose you were to explain this to a classmate, could you find a way to solve the problem without guessing?
I am looking forward to reading your response.

Student's Name: John Instructor Comments: Lillian,
Good response for the first part of the question. However, for the second part of the question, I agree that it SHOULD be solved using calories. HOWEVER, the problem does not state that, and so her approach of 14/(14+36+15) should be accepted as correct. You may also want to give him a hint on explaining the challenge problem such as "try drawing a diagram." --Dr. Bowers
