My project is how fast does heat attract to different materials? The purpose
of this project is to inspect which type of material conducts more heat. Four different
materials will be put to the test: metal(aluminum), wood, glass, and plastic. For this experiment the metal, wood, glass, and plastic should be cut to the same size. Second, the four materials must go in the refrigerator for 30 minutes. Third, take the materials out of the refrigerator and place them under a 60 watt lamp. Fourth, record the temperature right away. To do this, place a thermometer under the material and record its temperature and do the same on the other materials. This should continue for 10, 20,….60 minutes. To conclude, take the data and of the experiment and put together a graph. The results of the experiment state that glass heated up faster than metal, wood, and plastic. All the materials started just about the same temperature. After 10 minutes
every one of the four materials was at the same temperature. After 20 minutes glass
started to increase in temperature while metal, wood, and plastic stayed at the same
temperature. After 40 minutes glass increased in temperature of 31 degrees Celsius. In
60 minutes glass had the highest temperature of 33 degrees Celsius, and metal (aluminum)
had the lowest temperature of 27 degrees Celsius. My hypothesis was wrong metal (aluminum) did not get the highest temperature, but glass did. Glass had a temperature of 33 degrees Celsius and metal (aluminum) had a temperature of 27 degrees Celsius and that was the lowest temperature out of all the
materials. Since I was using aluminum which is another type of metal, but with air particles
inside it conducted less heat. Glass, plastic, and wood were all supposed to have the lowest temperature, but it turned out to have the highest temperature. Several questions from me occurred during my project. Since aluminum is a metal why didn’t it conduct heat the fastest? My experiment was done inside what would happen if I did my experiment outside? Would the temperatures stay the same or alter?

First of all, since you have already done the experiment, the procedures should be in the past tense. The purpose of this project was to inspect... The materials were cut.. etc.

The next thing I would change is in the sentence this should continue for 10, 20, ... 60 minutes. Instead, it would be better to say Additional temperature reading were taken every 10 minutes over a period of 60 minutes. (Or something along those lines).

Also, when you're typing the temperatures, instead of writing out 27 degrees Celsius, you should use the degree symbol and a C. To get a degree symbol, you can use superscripts (go into the font edit section of your word processor to do this, if you do not already know how to do these). So your temperatures would like like 27o C (with the zero as a superscript, which Yahoo Answers doesn't support).

The sentence "Since I was using aluminum which is another type of metal, but with air particles
inside it conducted less heat." doesn't seem to make sense to me. What was the original type of metal? Was the aluminum hollow and that's why there were air particles inside? In your next sentence, you should also clarify that the "it" is in reference to the glass, or change it to "they" if you were referring to all three.

Several questions occurred *to* you during your project.

My experiment was done inside. What would happen if I did my experiment outside; would the temperatures stay the same or alter?

Hope this helps!

I've listed questions I have for you in parenthesis. There were a few things I didn't understand, so I don't know how to word them better.

My project explores the question of how fast heat attracts to different materials. The purpose of this project is to inspect which type of material conducts more heat. Four different materials will be put to the test: metal(aluminum), wood, glass, and plastic.

For this experiment the metal, wood, glass, and plastic should be cut to the same size. Second, the four materials must be refrigerated for 30 minutes. Third, take the materials out of the refrigerator and place them under a 60 watt lamp. Fourth, record the temperature right away. To do this, place a thermometer under the material and record its temperature. So the same on the other materials. This should continue for 10, 20,….60 minutes. To conclude, take the data of the experiment and put together a graph.

The results of the experiment were that the glass heated up faster than metal, wood, and plastic. All the materials started at just about the same temperature. After 10 minutes, every one of the four materials was at the same temperature. After 20 minutes, the glass started to increase in temperature while the metal, wood, and plastic stayed at the same temperature. After 40 minutes, the glass increased in temperature 31 degrees Celsius. After 60 minutes, the glass had the highest temperature of 33 degrees Celsius, and the metal (aluminum) had the lowest temperature of 27 degrees Celsius.

My hypothesis was wrong metal (aluminum) did not rise to the highest temperature, but glass did. Glass had a temperature of 33 degrees Celsius, and metal (aluminum) had a temperature of 27 degrees Celsius, which was the lowest temperature out of all of the materials. Since I was using aluminum which is another type of metal (I'm not sure what you mean here. As opposed to what other kind of metal?), but with air particles inside, it conducted less heat. Glass, plastic, and wood were all supposed to have the lowest temperature (according to whom?), but it turned out to have the highest temperature (this isn't clear. What is the "it" here?).

Several questions occurred to me during my project. Since aluminum is a metal, why didn’t it conduct heat the fastest? My experiment was done inside. What would happen if I did my experiment outside? Would the temperatures stay the same or alter?

Don't say aliminum has air in it.

Tell if the materials were different distances from the light.

Say you wonder if the thermometer was being heated from the light of the lamp passing through the glass.
Or what temp would show on the thermometer right there but not behind any material.

Check to make sure you don't assume the temperatures are caused by conductivity. Notice they all heated at about the same speed.

I would have used a low flame and long strips, taking the temp at the other end constantly for 10 minutes.

Keep in mind this is a science report and not an English class assignment. (Unless it is!) If so, you're toast.

Read through & get rid of the language that sounds like chatting examples are "right away" should be immediately & every one should be each & for 10,20...60 should be every 10 minutes.
In "data and of" is just data of.
"Since I was using aluminum which is another type of metal, but with air particles inside it conducted less heat." I used aluminum a metal which contains air particles causing it to conduct less heat.
Good job but tighten your edges.

Are you nuts?? Do you actually expect anyone to read your very long "question" and then spend their time doing your homework for you?? I guess this just ain't your day!!

Do you honestly expect people to sit here and do YOUR homework while you just take it easy???!!!!

ask you parents to edit it
