1. Magnetism:
* Materials: A magnet, a piece of paper or plastic
* Method:
* Hold the magnet above the mixture.
* The powdered iron will be attracted to the magnet.
* Gently move the magnet over the mixture, collecting the iron on the paper or plastic.
2. Water and Filtration:
* Materials: Water, a container (like a beaker or bowl), a filter paper, a funnel
* Method:
* Add water to the remaining mixture (sugar and sawdust).
* Stir well to dissolve the sugar.
* Carefully pour the mixture through the funnel lined with filter paper.
* The sawdust will be trapped by the filter paper.
* The sugar solution will pass through the filter paper.
3. Evaporation:
* Materials: The sugar solution, a shallow pan or dish
* Method:
* Pour the sugar solution into the pan.
* Allow the water to evaporate slowly (you can use a low heat source or let it evaporate naturally).
* The sugar will be left behind as crystals in the pan.
Final Separation:
* You will now have the three components separated: the iron, sawdust, and sugar.
Important Note: This method assumes that the sawdust is not too fine. If the sawdust is very fine, it might pass through the filter paper.
