Student were given a mkxture of marbles,salt sand,and pebbles. Most efficent way to separate this listing 5 step direcxion and the method and what you will be separating?
Varying sieves?
To separate a mixture of marbles, salt, sand, and pebbles efficiently, you can follow these five steps:
1. Sort by Size: Start by sorting the mixture based on the size of the components. It will help you identify the marbles as they will generally be larger than the other components.
2. Use a Magnet: Since marbles are usually made of glass and not magnetic, you can use a magnet to separate them from the mixture. Pass a strong magnet over the mixture, and the magnetic pebbles (if any) will be attracted to it, allowing you to separate them.
3. Dissolve Salt: One method to separate salt from the mixture is by dissolving it in water. Pour the mixture into a container of water and stir it well until the salt dissolves. The sand and pebbles will settle at the bottom, while the saltwater can be separated by pouring it into another container.
4. Filter: Use a filter, such as a fine-mesh sieve or coffee filter, to separate the sand from the pebbles. Pour the mixture over the filter, and the sand will pass through while the pebbles will remain behind.
5. Evaporate Water: To separate the salt from the water obtained in step 3, you can heat the container of saltwater gently. The water will evaporate, leaving behind the salt crystals.
By following these steps, you will successfully separate the marbles, salt, sand, and pebbles from the initial mixture.
