What method would you use to separate a solid and a liquid, and keep the liquid?

The method you would use to separate a solid from a liquid while keeping the liquid is called filtration. Here are the steps:

1. Gather your materials: You will need a filter (like a coffee filter or a piece of cloth), a funnel, and a container to catch the liquid.

2. Place the filter in the funnel: The filter will catch the solid particles while allowing the liquid to pass through.

3. Pour the mixture into the funnel: Do this slowly to prevent the filter from overflowing or tearing.

4. Wait for the liquid to pass through the filter: The liquid will pass through the filter and be collected in the container below, while the solid will be left behind on the filter.

5. Collect the liquid: Once all the liquid has passed through the filter, you can remove the funnel and filter. The liquid in the container is now separated from the solid.

Remember to handle all materials with care, especially if the substances involved are hazardous.
