Question

2 explain how you would separate a mixture of soil, pebbles, and iron filings.

Explanation:

1. First, use a sieve to separate pebbles from the mixture (pebbles are larger, so they stay in the sieve while soil and iron filings pass through).
2. Then, use a magnet to attract the iron filings (iron is magnetic, so it will stick to the magnet, leaving soil behind).

Answer:

1. Use a sieve to separate pebbles (larger particles) from soil and iron filings.
2. Use a magnet to attract and separate the iron filings from the soil (since iron is magnetic).
