MIXTURES

SCIENCE-THIRD PRIMARY YEAR CEIP CORTES DE ARAGÓN

(Teacher: Miguel Navarro)

- A MIXTURE IS SOMETHING THAT CONTAINS TWO OR MORE DIFFERENT MATERIALS

- IN SOME MIXTURES WE CAN SEE THE DIFFERENT MATERIALS, FOR EXAMPLE IN A SALAD

- IN OTHERS, IT IS IMPOSSIBLE TO SEE THE DIFFERENT MATERIALS, FOR EXAMPLE IN A MILKSHAKE (BATIDO)

SEPARATING MATERIALS IN A MIXTURE

- WE CAN SEPARATE SOME MATERIALS IN A MIXTURE BY SIEVING, FILTERING OR EVAPORATING

1.- SIEVING: GOOD FOR SEPARATING SOLIDS OF DIFFERENT SIZES

2.- FILTERING: GOOD FOR SEPARATINGSOLIDS AND LIQUIDS

3.- FILTERING: GOOD FOR SEPARATINGA SOLID THAT IS DISSOLVED IN A LIQUID
