Year 8 chemistry

Learning Outcomes

Students must be able to:
-recognise the states of matter.
-state the properties of solids, liquids and gases.
-explain the change of state in terms of the particle theory.
This can be done through the completion of a model or other project.
-explain melting, freezing, evaporation and condensation in terms of the particle theory.
-recognise that the atom is the smallest particle of matter.
-describe the structure of an atom and its subatomic particles.
-describe how electrons are arranged in the first two energy levels.
-explain simple behaviour of an atom according to its electronic configuration.
  Atom game
-identify an element, a compound and a mixture.
-recall the symbols for the first twenty elements and identify the elements in a compound given its chemical formula.
-explain the atomic number and atomic mass of elements.
-explain how elements that have similar properties are arranged in groups, in the periodic table.
-distinguish between a chemical and a physical change with examples.
-identify the products and reactants of simple chemical reactions around the home.
-write word equations for simple chemical reactions. Link
-identify isotopes of an element. Link
-recall that density is the amount of mass divided by the volume it occupies. Link
