Ask your kids if they know which solids dissolve in water and set up this super simple science experiment to test their answers!
Everything is made of particles which are always moving. When a soluble solid ( solute ) is mixed with the right liquid (solvent), it forms a solution. This process is called dissolving.
Two things that affect the speed at which a solid dissolves are temperature and the size of the grains of the solid. Caster sugar which is made of fine particles will dissolve quickly, but bigger sugar particles will take longer.
