1) Separating Substances- The first thing our group did was separate all of the items that were in the cup. Such as, rocks, salted water, iron fiolence, sticks and dirty sand.
2) Purifying Water- This step requires you to put the dirty salted water in a beaker.
3) Then, you get a graduated cylinder and put a plastic funnel on op of it. Next, put a piece of paper in the funnel and mold it to the shape of the funnel.
4) Pour the salted water from the beaker into the graduated cylinder to purify the water.
5) Then, pour the water back into the beaker and place the beaker on a hot plate and wait for results to appear.
6)After a short while the results should be that the water evaporated because of heat and all that’s left is the salt.
