Year 3 (Challenging)



  • Can they explain how the muscular and skeletal systems work together to create movement?
  • Can they classify living things and non-living things by a number of characteristics that they have thought of?
  • Can they explain how people, weather and the environment can affect living things?
  • Can they explain how certain living things depend on one another to survive?
  • Can they classify a range of common plants according to many criteria (environment found, size, climate required, etc.)?




  • Can they compare and group together different rocks on the basis of their appearance and simple physical properties?
  • Can they describe and explain how different rocks can be useful to us?


  • Can they describe and explain the differences between sedimentary and igneous rocks, considering the way they are formed?
  • Can they describe in simple terms how fossils are formed when things that have lived are trapped within rock?
  • Can they recognise that soils are made from rocks and organic matter?


Year 3 (Challenging)


  • Can they classify igneous and sedimentary rocks?


  • Can they begin to relate the properties of rocks with their uses?



Light, Forces and Magnets


Forces and magnets


•  Can they compare how things move on different surfaces?

•  Can they recognise that they need light in order to see

•  Can they observe that magnetic forces can be transmitted


without direct contact?

•  Can they recognise that dark is the absence of light?

•  Can they observe how some magnets attract or repel each

•  Can they notice that light is reflected from surfaces?


•  Can they recognise that light from the sun can be

•  Can they classify which materials are attracted to magnets

dangerous and that there are ways to protect their eyes?

and which are not?

•  Can they recognise that shadows are formed when the light

•  Can they notice that some forces need contact between

from a light source is blocked by a solid object?

two objects, but magnetic forces can act at a distance?

•  Can they find patterns in the way that the size of shadows

•  Can they compare and group together a variety of


everyday materials on the basis of whether they are


attracted to a magnet?


  • Can they identify some magnetic materials?
  • Can they describe magnets have having two poles (N & S)?
  • Can they predict whether two magnets will attract or repel each other depending on which poles are facing?


Year 3 (Challenging)


  • Can they investigate the strengths of different magnets and find fair ways to compare them?
  • Can they explain why lights need to be bright or dimmer according to need?
  • Can they explain the difference between transparent, translucent and opaque?
  • Can they explain why lights need to be bright or dimmer according to need?
  • Can they make a bulb go on and off?
  • Can they say what happens to the electricity when more batteries are added?
  • Can they explain why their shadow changes when the light source is moved closer or further from the object?
