For the nails, you can use a magnet. You can separate the marbles and corks by putting it in water, wood floats and marbles don't.
Iron filings and sulfur are a mixture of two different substances, so they are considered heterogeneous because the individual components can be visually distinguished.
A magnet can be used to separate iron filings from sulfur as iron is magnetic whereas sulfur is not. Simply pass a magnet over the mixture to attract and remove the iron filings, leaving the sulfur behind.
It's just physical, unless you heat the mixture. The simple combination of iron and sulfur is a physical mixture: It can be separated with a magnet, and the iron and sulfur are still themselves. The situation changes if you heat the mixture hot enough to start a reaction between the sulfur and iron. If you do so, assuming the ingredients are in the right proportions, you'll have iron sulfide (a compound) and no free iron or sulfur will remain. In that case, you have a chemical reaction.
Iron sulfur mixture is magnetic because iron is a ferromagnetic material; meaning it can be magnetized and retain its magnetism. When iron is combined with sulfur to form a mixture, the presence of iron in the mixture imparts magnetic properties to it.
Iron and sulfur form a mixture known as iron sulfide, often called pyrite or fool's gold. This mixture can be created by heating a combination of iron and sulfur powders in a controlled environment.
They are both mixtures.
Here's the full scientific report I had to do in year 7. Title: Magnetic Separation Aim: To separate iron filings from sand using a magnet. Equipment: Magnet, sand and iron filing mixture, plastic bowl Method: 1. Pour the mixture into the plastic bowl 2. Move the magnet slowly through the mixture Results: When the magnet was moved through the mixture, it picked up the iron filings but not the sand. Conclusion: In this experiment we demonstrated that a magnet can pick up iron filings in a sand and iron filing mixture through magnetism. The aim was achieved as we were able to separate the iron filings from the sand.
The hypothesis for separating iron filing and sulfur powder using a magnet is that iron is a magnetic material, whereas sulfur is not. By using a magnet, we can separate the iron filings from the sulfur powder based on their magnetic properties.
Wooden cork is less dense than the water and the iron is not.

You can use a magnet to separate iron filings from wood shavings. Simply pass the magnet over the mixture and the iron filings will be attracted to the magnet, leaving the wood shavings behind. You can then easily separate the two components.
Because iron is rusting.
No, iron filings are not a mixture
Cork is lightweight, buoyant, and has insulating properties, while iron is dense, heavy, and a good conductor of heat and electricity. Cork is flexible, while iron is rigid. Cork is typically used in insulation, gaskets, and flooring, while iron is used in construction, machinery, and tools.
Iron is a chemical element not a mixture.An iron alloy is a mixture.
Iron ore is a mixture.
