Year 6 focus on forces, dissolving, reversible and irreversible change, how we see things, electrical circuits, interdependence and adaptation.

Forces
Most children will: identify that weight is a force and is measured in newtons; describe some situations in which there is more than one force acting on an object; draw diagrams to illustrate forces acting on an object; use a forcemeter accurately to measure forces; present measurements in simple line graphs and identify patterns in these and evaluate explanations.

Dissolving
Most children will: recognise that solids remain in the solution when they dissolve and can be recovered by evaporation; identify several factors that affect the rate at which a solid dissolves; investigate an aspect of dissolving, presenting results obtained in a suitable graph and explaining what the results show.

Reversible and irreversible change
Most children will: use careful observation to describe a number of changes; classify some changes eg dissolving as reversible and others eg burning as irreversible; recognise that irreversible changes often make new and useful materials and recognise the hazards of burning materials.

How we see things
Most children will: recognise that light travels from a source, that when it is blocked, a shadow is formed and when it hits a shiny surface, it is reflected; that light sources are seen when light from them enters the eyes; make careful measurements of shadows and represent these in a line graph.

Electrical circuits
Most children will: suggest ways of changing the brightness of a bulb in a circuit; draw circuit diagrams and construct circuits from diagrams using conventional symbols; set up a circuit which can be used to investigate an idea and use knowledge about electrical conductors and insulators to answer questions about circuits.

Interdependance and adaptation
Most children will: recognise that a green plant needs light and water to grow well and that it produces new material from air and water; describe how animals in two habitats are suited to the conditions; represent feeding relationships in food chains beginning with a green plant and use keys to identify animals and plants.
