  - Lesson 01 - What is the difference between solid, liquid and gas? Lesson Plan Lesson Title

        EW: In terms of energy and particles, explain what happens to a substance as it changes from a solid to a liquid.
    - The amount of energy needed to change state from solid to liquid and from liquid to gas depends on the strength of the forces between the particles of the substance. The nature of the particles involved depends on the type of bonding and the structure of the substance. The stronger the forces between the particles the higher the melting point and boiling point of the substance.
    - (HT only) Limitations of the simple model above include that in the model there are no forces, that all particles are represented as spheres and that the spheres are solid.

  - Lesson 03 - Why do some reactions appear to have a mass change? Lesson Plan Lesson Title
    - Some reactions may appear to involve a change in mass but this can usually be explained because a reactant or product is a gas and its mass has not been taken into account. For example: when a metal reacts with oxygen the mass of the oxide produced is greater than the mass of the metal or in thermal decompositions of metal carbonates carbon dioxide is produced and escapes into the atmosphere leaving the metal oxide as the only solid product.

This process is called electrolysis.

 existence there was intense volcanic activity that released gases that

 amount of carbon dioxide in the atmosphere. No knowledge of other
 theories is required.

 https://www.youtube.com/watch?v=s5p6Nk3SzcU
 - Metals, glass, building materials, clay ceramics and most plastics are produced from limited raw materials.
 - Much of the energy for the processes comes from limited resources.
 - Obtaining raw materials from the Earth by quarrying and mining causes environmental impacts.
 - Suggested Activity:
 Extended writing: Describe the environmental impacts of obtaining raw materials from the Earth.
 - Some products, such as glass bottles, can be reused. Glass bottles can be crushed and melted to make different glass products. Other products cannot be reused and so are recycled for a different use.
 - Metals can be recycled by melting and recasting or reforming into different products.
 - The amount of separation required for recycling depends on the material and the properties required of the final product. For example, some scrap steel can be added to iron from a blast furnace to reduce the amount of iron that needs to be extracted from iron ore.

 - Lesson 03 - How is water made safe for human consumption? Lesson Plan Lesson Title
 - Water of appropriate quality is essential for life. For humans, drinking water should have sufficiently low levels of dissolved salts and microbes.
 - Urban lifestyles and industrial processes produce large amounts of waste water that require treatment before being released into the environment.
 - Water that is safe to drink is called potable water. Potable water is not pure water in the chemical sense because it contains dissolved substances.
 - Suggested Activity:
 Compare the composition of:
 â€¢ potable water
 â€¢ pure water.
 
 Why do we not drink pure water?
 - Sewage and agricultural waste water require removal of organic matter and harmful microbes. Industrial waste water may require removal of organic matter and harmful chemicals.
 - Suggested Activity:

 ? anaerobic digestion of sewage sludge
 ? aerobic biological treatment of effluent.
 - In the United Kingdom (UK), rain provides water with low levels of dissolved substances (fresh water) that collects in the ground and in lakes and rivers, and most potable water is produced by:
 - choosing an appropriate source of fresh water
 - passing the water through filter beds
 - sterilising.

    - T: The solid added is called the solute. - KS3.C.08
    - T: The liquid added is called the solvent. - KS3.C.08
    - T: The large solute (solid) crystal break down into smaller molecules which fit between the particles of the solvent. - KS3.C.08
    - W: The solid can now behave like a liquid as the small molecules can move relative to each other. - KS3.C.08
    - T: A saturated solution is one that can not dissolve any more solute. - KS3.C.08
    - W: When all the gaps between particles are full, no more solute can be dissolved. - KS3.C.08
    - W: Increasing the temperature of the solvent, increases the speed the particles collide, creating bigger gaps.
      
      This allows more solute to dissolve in the solvent. - KS3.C.08
      - Suggested Activity:

      Our knowledge of the structure of the Earth comes mainly from studying how the shockwaves from earthquakes (seismic waves) travel through it.
      
      Earthquakes produce two types of waves that can travel through the Earth:
      - Longitudinal faster travelling Primary, P (pressure) waves, which move through liquids as well as solids;
      - Transverse slower travelling Secondary, S waves, which travel only through solids.
      
      The S-wave shadow is what give rise to the idea of a core.
