Separating Mixtures

  1. 1. By Chloe and Katie
  2. 2. Step 1. Separating the rice from the rest. In this picture it shows how we had to pour the mixture into a sieve over a beaker. When we shook the mixture through everything fell into the beaker but not the rice. When it was just the rice left we poured it all into a small beaker.
  3. 3. Step 2. Pulling out the Iron Filings. In this step we used a magnet wrapped in gladwrap to separate the Iron Filings from the salt and sand. We covered the magnet with gladwrap because the Iron sticks to the magnets very strongly. As you can see in the picture when we lowered the magnet into the mixture and all of the Iron came out. Then we pulled the Iron off the magnet and put it into it’s own little beaker.
  4. 4. The Rice and Iron Filings. Now that we had the rice and iron separated and clean, we sat them on a tray and then continued with the process.
  5. 5. Step 3. Filtering the salt through the sand. In this step we had to mix the salt and sand together then add some water. Once we added the water we poured the mix into a funnel that had filter paper inside it. The water and the salt filtered through the paper then leaving it in the beaker and leaving the sand in the filter paper. We then put the sand into a small beaker and that was finished with the sand.
  6. 6. Step 4. Boiling the salty water. In this step we boiled the water that had the salt in it. The process is to turn on the gas, light the Bunsen burner, then wait for the water to start evaporating. Once the water has all evaporated you will be left with a bowl full of cooked salt!
  7. 7. This is what our salt looked like when it had been separated from the water!
  8. 8. The finished products!
