Put them in water. Sugar dissolves, sand remains Filter the solution to separate sand and salt. Evaporate solution with dissolved salt to get salt back
The substance that is not soluble in water is sand. Salt, sugar, and powdered drink mix are all soluble in water and will dissolve when mixed with it.
water and sand there is dissolved sugar or salt with sand
If you mix salt and water, the salt will dissolve into the water. If you mix pebbles and water, the pebbles and water will stay being separate objects
Salt lowers the freezing point of water, causing the ice to melt faster than it would with sugar or sand. When salt is added to ice, it disrupts the hydrogen bonding between water molecules, making it easier for the ice to melt. Sugar and sand do not have the same effect on lowering the freezing point of water.

Salt, sugar, and sand are all granular substances but differ in composition and usage. Salt and sugar are compounds with distinct tastes - salt is made of sodium and chloride, while sugar is made of carbon, hydrogen, and oxygen. Sand is composed of silica and does not dissolve in water like salt and sugar do.
salt and sugar
When salt, sand, and sugar are mixed with water, salt dissolves completely to form a clear solution, sugar dissolves to form a clear solution, and sand does not dissolve but settles at the bottom. The water molecules surround and separate the salt and sugar molecules, allowing them to mix uniformly, while the sand remains separate due to its larger particle size.
Salt
Sand is not soluble in water. Sugar, salt, powder drink mix are all soluble substances that can dissolve in water.
The substance that is not soluble in water is sand. Salt, sugar, and powdered drink mix are all soluble in water and will dissolve when mixed with it.
mixture of salt and sugar, sand and soil etc.
water and sand there is dissolved sugar or salt with sand
I would use the property of solubility in water; sugar is highly soluble in water and sand is highly insoluble.
If you mix salt and water, the salt will dissolve into the water. If you mix pebbles and water, the pebbles and water will stay being separate objects
You need to determine what you think will melt the fastest, and that will be your hypothesis. If you think that pepper will melt it faster, you would say "My hypothesis is that the pepper will melt ice faster than the other variables (sand, salt, and sugar)."
