This is a hypothetical experiment that I have to write a lab report on.
I have to design an experiment to solve the problem: You have a mixture of sand, water, and gravel. How do you separate this mixture into different parts?
I need to know what I should put in the chart. I hypothesized that the water will be separated when it is heated. After all of the water is gone, the sand will be separated after it is strained from the gravel. So I would do that for the procedure. I just don't know what I should put in the chart. Like what information should go in there?
Please help, I really appreciate it...If you need some more information or for any other reason pertaining to this question, feel free to email me...I just need some answers, please!!!

Okay, I will filter out the water then. But what information should go in the chart? I haven't really been getting much of an answer...Please help! I really appreciate it!!!

The easiest way to separate these items is like this.
I assume the mixture is in a bucket of some type.
Get another container and cover it with 1/4 inch mesh screen.
Stir contents, then pour it over the screen and it will separate the gravel. Remove screen with gravel and set aside.
Put a cloth towel over the bucket you just emptied. Stir and pour the sand water mixture over it to separate the sand.
Charting. Give reason for experiment such as need to clean the mixture for a goldfish bowl.
List the items used.
On your paper you would have a single line say 6 inches long and then broken into three sections.
|--Gravel--|--Sand--|--Water--|
Explain the process in which you removed the gravel.
Next you would show this
|--Sand--|--Water--|
Explain sand removal and then final charting would be
|--Water--|
If I understood the question this should be good.

Not all experiments need a chart. Did the teacher insist that you need one?
By the way, I'm not even sure you could call this an experiment....
But, if you know the starting amounts or water sand and gravel. Then you know how much you should end up with when you separate them. So you could make a bar chart to show the percentage of the starting amount you end up with...
maybe you could compare two different ways...
For example.... heating wasn't the first thing I thought of.... I thought of pouring the water away through a filter....
If you heat it.... how are you going to recapture it...
anyway...one way or the other will end up with more water

good techniques, i would have said filter out the water first with a micro-screen, then sift the gravel from the sand using a larger filter screen.
The scientific process defines how to present your work. http://en.wikipedia.org/wiki/Scientific_method
i would separate it into groups. first, you need to explain the experiment, what it is that you are trying to achieve.
next comes the materials, what is physically involved in the study.
next, you should tell about your method. what you will do, and why you think it will work.
then, you give your hypothesis, what do you think the outcome of the experiment will be?
then, you list your data. what happened when you performed the experiment? list the steps you took, and the reactions that occured.
and finally, the conclusion. what actually happened during the experiment. and compare this to your hypothesis.

Use distillation to get the water out then a strainer to separate the sand and gravel.

one million. Look behind your guide two. Look on the textual content books website online, in case you cross via a few stuff it must have the reply web page someplace three. If that does not paintings, I'd simply undergo via doing it

you can evaporate all the water out
