Chemistry Overview
The following are the main topics which we will be covered in grade 7.
States of matter
Show in outline how the particle theory of matter can be used to explain the
properties of solids, liquids and gases, including changes of states, gas
pressure and diffusion.
The structure of atoms
The size of atoms
Atomic structure
Atomic number and mass number
Electronic structure
Material properties
Distinguish between metals and non-metals.
Describe everyday materials and their physical properties.
Give the symbols of the first 20 elements of the periodic table
Understand that elements are made of atoms.
Explain the idea of compounds.
Name some common compounds including oxides, hydroxides, chlorides,
Sulfates and carbonates.
Distinguish between elements, compounds and mixtures.
Expansion and contraction.
Air pressure.
Matter and density.
Experiments in chemistry
Apparatus in chemistry
Measurement in chemistry.
Laboratory safety rules.
Hazard symbols.
