the picture shows a mixture in a dish that a student has created by combining sand in iron filings.Which is the best way for the students to separated this mixture

Answer 1

The best method for separating a mixture of sand and iron filings is through the use of a magnet. Here's how the process works:

1. Use a Magnet: Bring a magnet close to the mixture. The iron filings will be attracted to the magnet, while the sand will not.

2. Separation: Once the iron filings are attracted to the magnet, they can be pulled away from the sand.

3. Collecting the Components: You can either wipe the iron filings off the magnet onto a separate dish or gently brush them off, leaving the sand behind.

This method is effective because it takes advantage of the magnetic properties of iron, allowing for a simple and quick separation without the need for water or other solvents.
