Volume – How much space something takes upMass - How much matter is in an object
DISSOLVING Solvent – liquid which dissolves substances
e.g. water Solute – The substance that is dissolved e.g.
sugar The solute can only be collected by
evaporating the solvent. E.g. salt from salt water
Solution – A liquid made up of a solvent and a solute
Suspension – when you shake an insoluble substance in water, it doesn’t dissolve. E.g. mud in water.To separate the mud from the water - filter

FEATURES OF LIVING THINGS Take in chemicals from outside them Use food to grow Make waste Grow Respond to changes around them Reproduce
SEDIMENTATION The process of letting an insoluble
substance settle to the bottom of a container. E.g. mud settling in water.
VERTEBRATESa. Fish
Moist Scales Must live in water Reproduce by eggs/live young
b. Amphibians E.g. frogs Must live near water Moist skin with no covering Breathe with lungs (on land) Lay eggs in water
c. Reptiles E.g. Snake Dry, scaly skin Can live in deserts Lay eggs with tough, leathery shells Breathe with lungs.
