Unit 3 - Separate it (The Earth's resources)

Content

• The kinetic theory of particles and motion
• States of matter and changes of state
• The aggregation of particles into matter
• Particles as atoms and molecules
• Aggregation of matter as elements and compounds
• The periodic table as a data table of the elements (atoms)
• Pure substances and mixtures
• Solutions and dissolution
• Crystallisation and precipitation
• Separation of mixtures, filtration, decanting, evaporation, distillation, magnetic separation, floatation
• Chemical techniques to obtain new materials (electrolysis)

Skills and understanding

• Work safely in science laboratories
• Recognise mixtures and pure substances
• Use solutions as a type of mixture
• Use the concept of solution concentration (dilute, concentrated, saturated) appropriately.
• Physically separate mixtures using a variety of techniques (filtering, dissolving, evaporation, condensation, distillation)
• Recognise elements and compounds
• Identify common element symbols and locate them in the periodic table
