By contributing to investigations into familiar changes in substances to produce other substances, I can describe how their characteristics have changed. 

SCN 2-15a

Benchmarks:

·  Investigates and explains physical changes to the properties of materials which are fully and partially reversible, for example, salt dissolving in water, chocolate melting and water freezing.

·  Uses scientific vocabulary such as ‘melting’, ‘freezing’, ‘evaporating’ and ‘condensing’ to describe changes of state.

·  Investigates and records chemical changes to the properties of materials which are irreversible, for example, cooking, rusting and striking a match.

· Observes and identifies some of the signs of a chemical reaction, for example, production of bubbles, colour/texture change and heat given out/taken in.

· Explores and describes the characteristics of solids, liquids and gases, for example, solids retain the same volume and shape, liquids keep the same volume but the shape changes to fit the container and that gases change shape and volume to fill the container.
