Separating Mixtures

Procedures:

1. First, remove toothpicks from heterogeneous mixture with your hands.

2. Secondly, remove the marble with the spoon.

3. Take the beans out with the spoon.

4. Then, turn the filter paper into a cone and put it into the funnel. Following this, put the funnel on top of the graduated cylinder. After this, put the beans into the funnel and pour the mixture through the funnel.

5. Once the water goes into the graduated cylinder, take the beans out with your hands and put them aside on the tray.

6. Then, use the magnet to pick up the iron fillings from the funnel. Put the iron fillings onto the tray.

7. After that, dump the sand in the filter onto the tray.

8. Next, remove the funnel from the graduated cylinder.

9. Following this, pour the remaining mixture into the Erlenmeyer flask. Then, turn the hot plate on and put the flask onto the hot plate. This will separate the salt from the water.

10. Once the water is evaporated, you should see the salt. Turn the hot plate off and use the tongs to remove the Erlenmeyer flask from the hot plate. Place the flask onto the table (not the tray!).

11. Lastly, clean up your area.

The seven parts are now separated!
