On the first page of each of the QCA units there is a section entitled "Expectations". Those for Unit 6E are shown below: 


Unit 6E Balanced and unbalanced forces

EXPECTATIONS
at the end of this unit

most children will:                   Identify that weight is a force and is measured in newtons; 
                                      describe some situations in which there are two forces acting 
                                      on an object and recognise that when the object is at rest, the 
                                      forces are balanced; 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

some children will not have made      identify weight as a force; recognise that more than one force 
so much progress and will:            can act on an object; measure forces using a forcemeter and 
                                      present measurements in tables

some children will have               describe and explain the motion of some familiar objects in terms
progressed further and will also:     of balanced or unbalanced forces



                    from QCA  (1998) "A Scheme of Work for Key Stages 1 and 2: Science"





It is these statements that have been modified into "I can..." statements that the children can use (with the "easiest" block placed first). The "I can..." statements for Unit 6E are shown below: 





[_]  I know that weight is a force
[_]  I know that more than one force can act on an object.
[_]  I can measure forces using a forcemeter.
[_]  I can present my measurements in tables.

         ----------------------------------

[_]  I know that weight is a force and is measured 
     in newtons.
[_]  I can describe some situations in which there are 
     two forces acting on an object.
[_]  I know that when the object is at rest, the forces are balanced.
[_]  I can draw diagrams to illustrate forces acting on an object.
[_]  I can use a forcemeter accurately to measure forces.
[_]  I can present measurements in line graphs.
[_]  I can identify patterns in measurements shown on a line graph.

         ==================================

[_]  I can describe the motion of some familiar objects.
[_]  I can explain the motion of some familiar objects in terms of 
     balanced or unbalanced forces.
