In Science this term, we will be looking at the properties and changes of materials. During this Science topic the children will be taught:
To compare and group together everyday materials on the basis of their properties:
• response to magnets
• conductivity (electrical and thermal)
Also they will learn that:
o Heat always moves from hot to cold.
o Some materials (insulators) are better at slowing down the movement of heat than others.
o Objects/liquids will warm up or cool down until they reach the temperature of their surroundings.
The children will be able
To give reasons, based on evidence from comparative and fair tests, for the particular uses of everyday materials, including metals, wood and plastic
• To describe how a material dissolves to form a solution; explaining the process of dissolving.
• To describe and show how to recover a substance from a solution.
• To describe how some materials can be separated.
• To demonstrate how materials can be separated through:filtering ,sieving ,evaporating and magnetic attraction
• To demonstrate that some changes are reversible and some are not.
• To explain how some changes result in the formation of a new material and that this is usually irreversible.
• To discuss reversible and irreversible changes.
