Science lab question (separating mixture)?

Question

Equipments that can be used during the lab are the following:
(Tirrell burner, rubber tubbing, evaporating dish, 4 beakers, filter paper, a funnel, watch glass, scoopula, forceps, glass stirring rod, distilled water, wash bottle, magnet, tape and zip-lock bags.)

Using the above list of equipments, the objective is to separate the mixture (containing sawdust, salt, sand, and iron) into four pure individual components.

I just need the procedure of this science experiment. Please list them out in bullet points, not in paragraph form. Thank you so much for helping!

Answer 1

1. remove iron with a magnet.
2. add water then filter it. when you evaporate the water you will get salt.
3. let the remaining mixture dry out.
4. use a sieve to separate sawdust from sand, the sand will come through, but the dust will remain on the sieve.

Answer 2

To separate the sawdust from the sand, put both into water. The sawdust will float, and you can scoop it off the surface, or overflow the containter and it will flow over the top of the container. The sand will remain at the bottom.

Answer 3

Rania75 was right except that you want use the water to seperate sawdust and sand based on density. Sawdust should float. Sand will sink.

Answer 4

Hmmm I don't think you can separate sawdust from sand with simple size-filtering...
