Pupils should be taught: a) how to separate solid particles of different sizes by sieving [for example, those in soil]

|
b) that some solids [for example, salt, sugar]
dissolve in water to give solutions but some [for example, sand, chalk] do
not
|
||||||||
|
c) how to separate insoluble solids from
liquids by filtering
|
||||||||
|
d) how to recover dissolved solids by
evaporating the liquid from the solution
