There are different ways to seperate the mixture but this is the way I found out how to do.
- Use your fingers to take out the two toothpicks and place them down on the tray.
- pour about 8ml into the graduated cylinder.
- Use the spoon to take out the beans one by one.
- Use the filter paper to filter out the water from the cup into the flask.
- Use your finger to take out the marble from the cup.
- Put the flask with water onto the hotplate and boil for about 5-10 min.
- Use the filter paper to filter out the water from the graduated cylinder to the beaker.
- Use the magnet to take out the iron shavings in the cup and put them on a piece of paper towel.
- Take off the water once boils and use the tongs to place it on the table.
- Use the magnify glass to see the particles of salt in the flask.
- You now have all materials in the mixture, salt, water, beans, sand, iron shavings, marble, and toothpicks.
