Separating Sand from Water by Filtration:
Filtration is a process used to separate solid particles from a liquid by passing the mixture through a filter. In the case of separating sand from water, filtration is an effective method to use. Here's how it works:

1. Set up the filtration apparatus:
- To begin, you will need a funnel, filter paper, and a beaker. Place the funnel in the mouth of the beaker and insert the filter paper into the funnel.

2. Pour the mixture through the filter:
- Slowly pour the sand and water mixture through the filter paper in the funnel. The filter paper will trap the sand particles while allowing the water to pass through.

3. Collect the separated components:
- As the water passes through the filter paper, it will collect in the beaker below, leaving the sand trapped on the filter paper. Once all the water has passed through, you can carefully remove the filter paper with the sand and set it aside.

4. Dry and collect the sand:
- Allow the sand on the filter paper to dry completely. Once dry, you can carefully remove the sand from the filter paper and collect it for further use or disposal.
By following these steps, you can effectively separate sand from water using the filtration method. This process is simple, cost-effective, and does not require any specialized equipment, making it a practical solution for separating these two substances.
