Separating Mixtures Through Filtration Evaporation Sieving and Magnetic Methods

Sabina Alejandro demonstrates various methods to separate mixtures, including filtration, evaporation, sieving, dilatation, and magnetic separation. Each experiment uses common materials to illustrate the principles behind these separation techniques.

What materials are needed for the filtration experiment?

• 1 cup of water, 1 1⁄2 cup of sand, cheese cloth, and 2 containers

• 1 cup of oil, 1⁄2 cup of sugar, cheese cloth, and 1 container

• 1 cup of water, 1 cup of flour, and a sieve

• 2 cups of water, 1 cup of sand, and a strainer

What is the purpose of using a cheese cloth in the first experiment?

• To dissolve the sand

• To evaporate the water

• To collect the sand from the mixture

• To mix the sand and water

What happens to the table after using the wet rug in the evaporation experiment?

• The table becomes sticky

• The table remains wet

• The table dries up

• The table changes color

Which method is used to separate rice grains and flour?

• Evaporation

• Magnetic separation

• Filtration

• Sieving

What is the method called when separating a mixture of water and sand in the fourth experiment?

• Magnetic separation

• Evaporation

• Dilatation

• Filtration

Which materials are used in the magnetic separation experiment?

• Coins, small rocks, nails, and magnets

• Nails, flour, rice grains, and magnets

• Coins, cheese cloth, water, and magnets

• Coins, sand, water, and magnets

What is the main principle behind magnetic separation?

• Using a magnet to attract certain materials

• Using a sieve to separate particles

• Using a cloth to filter out solids

• Using heat to evaporate moisture
