What Melts Ice The Fastest? Sugar/salt/sand/pepper?

I got to do a pjas project so I picked this project; but it turns out it's due tomorrow(the procedure anyway) and I got nothing down! Help!! I deduce I'm going crazy!;:


Answer:
It shouldn't take you all that long to do a simple version of this experiment for your project. And if you merely need to turn in a description of the procedure you are going to use, that's even easier, and you can get an conception by reading through this.

If you don't already have a given format to follow to describe your procedure, I would suggest you start with a statement of the project and what you are trying to figure out.  Then you label a guess as to what you think your answer will be--that's called a hypothesis--(your guess).   Which of the substances do you think will thaw ice fastest  and why? DO you know anything about the 4 substances chemically that might make a difference?  

Now describe what you plan to do:  For example, return with four ice cubes similar in size/shape and set them in 4 separate dishes (or you can use tabloid towels to set them on).  Sprinkle each ice cube with a 1/2 tsp. Of a substance (one next to sugar, the next with salt, subsequent with sand, next with pepper.  Write down the starting time on a piece of broadsheet. Leave them out at room temperature for 20 minutes and check on them.  Which one is melting fastest?  Can you see a difference?  Write down the time you observed and what you saw.  Leave them for another 20 minutes.  Again record the time and your observations.

You necessitate to do the experiment or project to have something to write down as far as what you observed, but you can lay out your paper like this.

1)Describe the experiment  - what you are trying to amount out/what question you are tyring to answer with this experiment
2)  state your hypothesis (what you expect will happen--what your guess is).

2) Describe your procedures.
3) Describe your observations in detail, and the times you observed, and what be occurring.

4) Write the conclusion:  (Which substance, if any seemed to melt the ice fastest? Why does that substance lower the melt point of ice?)
5)  Explain what happened.  Say what you know about the substance that melt the ice the fastest that might be the reason it did so.  Was there a chemical sensitivity that caused it?  What is that chemical reaction? Is the substance water soluble (dissolves surrounded by water) and is it possible some of the water molecules in the ice are individual displaced by the ones dissolving into the water/ice?  Does one of the water soluble substances have a "heavier" molecule that seems to displace the wet /ice molecules faster?
6) write a short conclusion telling if your hypothesis (guess) was right or not and why it was or wasn't

Good luck!


Comment: Excellent, Amore.
I newly wanted to add that in experiments similar to that, one should do at least 3 sets and then average out the results to get a more reliable conclusion.
Answer: Salt make ice melt the fastest,then sugar,later sand, then pepper.
Comment: Thanks!!=D
Answer: I finished my pro people =D
thanks for the comfort!!
Salt
