Cause and effect

Similarity and Difference


Working Scientifically




Identify and name a range of materials (wood, plastic, glass, metal, water and rock)


Describe physical properties of everyday materials


Classify and group according to a range of physical properties



Know the uses of different everyday materials (wood, metal, plastic, glass, rock, brick, paper, cardboard)


Classify and group materials based on their uses


Know that solid objects can be changed by squashing, bending, twisting and stretching



Compare and group solids, liquids and gases


Know that some materials change state (heating and cooling; no baking)


Identify the part played by evaporation and condensation in the water cycle

Compare and group everyday materials based on their properties including their hardness, solubility, transparency, conductivity (electrical and thermal) and response to magnets


Know and investigate through dissolving and mixing

reversible and irreversible changes


Know that some changes result in the formation of new materials


Use prior knowledge of solids, liquids and gases to know how mixtures might be separated (filtering, sieving and evaporating)


Use comparative and fair tests to give reasons for uses of everyday materials
