Our new science enquiry question is...
How do some materials change when heated or cooled?
(Properties and Changes of Materials)
We will be starting our new topic with an exciting workshop from Chemistry with Cabbage.
Children will be given equipment and household chemicals to do their own experiments throughout the day. They will make indicators, test household chemicals, look at the properties of acids, do reversible and irreversible changes. The worshop will cover evaporation, condensation, melting, dissolving, reversible reactions and states of matter.
Our two-week topic will cover the following National Curriculum objectives:
- compare and group together everyday materials on the basis of their properties, including their hardness, solubility, transparency, conductivity (electrical and thermal), and response to magnets
- know that some materials will dissolve in liquid to form a solution, and describe how to recover a substance from a solution
- use knowledge of solids, liquids and gases to decide how mixtures might be separated, including through filtering, sieving and evaporating
- give reasons, based on evidence from comparative and fair tests, for the particular uses of everyday materials, including metals, wood and plastic
- demonstrate that dissolving, mixing and changes of state are reversible changes
- explain that some changes result in the formation of new materials, and that this kind of change is not usually reversible, including changes associated with burning and the action of acid on bicarbonate of soda
Maths
We will be covering multiplication and division and fractions.
English
Our focus text is Farther and our writing genres are a setting narrative and a letter.
