1. salt solution / techniques ; water evaporates and heating salt crystals are left behind in the dish

2. sand and gravel / techniques ; A mixture made of solid particles of different sizes, for example sand and gravel, can be separated by sieving. What is a sieve? An instrument with a meshed or perforated bottom, used for separating coarse from fine parts of loose matter, and for straining liquids.
desc : Sand and gravel means any unconsolidated mixture of fine or coarse aggregate, or both, found in and processed from a natural deposit. ... Sand and gravel means any unconsolidated mixture of fine and/or coarse aggregate material found in a natural deposit.
water and oil techniques ; Gravity separation is the most widely used method for oil emulsion separation. The elements in the well stream such as oil and water have different gravities. The density differences allow water to separate by gravity.
desc :
When oil and water are combined, they do not mix evenly, but instead form two separate layers. Each of the layers is called a phase. Oil and water do not mix, instead forming two distinct layers called phases. The oil phase is less dense than the water phase, and so the oil floats on top of the water.
