Progression in Science: Chemistry

Science National Curriculum


Progression in Chemistry


Subject Key Objective Progression & Development by Year Group


The following is a guide to help you understand your child's progression through school.

All lessons are effectively differentiated to ensure that all children can achieve the objective set.


Chemistry Knowledge - EYFS


In EYFS, children will:


  • explore materials with different properties;
  • explore collections of materials with similar and/or different properties;
  • talk about the differences between materials and changes they notice.




Chemistry Knowledge - Year 1


In Year 1, children will:



  • know the name of the materials an object is made from;
  • identify and name a variety of everyday materials, including wood, plastic, glass, metal, water and rock;
  • know about the properties of everyday materials;
  • compare and group together a variety of everyday materials on the basis of their simple physical properties.




Chemistry Knowledge - Year 2


In Year 2, children will:


  • know how materials can be changed by squashing, bending, twisting and stretching;
  • know why a material might or might not be used for a specific job



Chemistry Knowledge - Year 3


In Year 3, children will:


  • compare and group rocks based on their appearance and physical properties, giving reasons;
  • know how soil is made and how fossils are formed;
  • recognise that soils are made from rocks and organic matter; 
  • know about and can explain the difference between sedimentary, metamorphic and igneous rock.








Chemistry Knowledge - Year 4


In Year 4, children will:


  • compare and group materials together, according to whether they are solids, liquids or gases;
  • observe that some materials change state when they are heated or cooled and measure or research the temperature at which this happened in degrees Celsius;
  • know the part played by evaporation and condensation in the water cycle and associate evaporation with temperature.




Chemistry Knowledge - Year 5


In Year 5, children will:


  • compare and group materials based on their properties (e.g. hardness, solubility, transparency, conductivity, [electrical & thermal], and response to magnets;
  • give reasons, based on evidence from comparative and fair tests for the particular uses of everyday materials, including metals, wood and plastic;
  • know and can explain how a material dissolves to form a solution; 
  • know and can show how to recover a substance from a solution;
  • use their knowledge of solids, liquids and gases to decide how materials can be separated (e.g. through filtering, sieving and evaporating); 
  • demonstrate that dissolving, mixing and changes of state are reversible changes;
  • explain how some changes result in the formation of a new material and that this is usually irreversible – include burning and acid on bicarbonate of soda.
