Pulling apart mixtures

In the beginning I made a crazy mixture with my crew (Nika and Tasha)we put sugar,  calcium chloride and marble chips. Stir, stir, stir til its all mixed together and we swabbed mixtures with another group. Not knowing whats in their container i got a magnet trying to pull the iron out, finding out their is none. I could tell their was a bunch of sugar, a little of marbles chips, sand and calcium chloride. Using a wired net, we separated the big chunks with the little sugars and sand which is called filtration. Marbles chips and calcium chloride in one container, sugar and sand in the other. We weighed the sand and calcium chloride. Used water to dissolve the calcium chloride and subtracted the marble with the total amount. Then on to the next container, sugar, sand and we added water. It was like a filter (filtration), a funnel cup with a paper folded in a certain way, we poured the whole mix in and it separated the sugared water and the sand. This took long time but it sure did work. Used math to get the measurements and BOOM separation complete!


This is how it was folded------>

And this is an example of a different type of filter:
