8C
- 8C.1
  - Lesson 01 - Where do rocks come from? Lesson Plan Lesson Title
    - There are lots of different rocks of all sorts of ages. - KS3.C.33
    - The oldest rocks are found in Africa, Canada and Australia. - KS3.C.33
    - The youngest rocks are found around volcanoes. - KS3.C.33
    - There has been no new rock material added to the earth since it was created apart from a small amount of meteorites. - KS3.C.33
    - New rocks are made from recycled material. - KS3.C.33
    - Igneous rocks are formed when molten rocks freeze. - KS3.C.33
      - Suggested Activity:
        https://www.geolsoc.org.uk/ks3/webdav/site/GSL/shared/pdfs/education and careers/RockCycle/Salol Experiment.pdf
        Equipment Required:
        Stearic acid
        Kettles
        Magnify glasses
        Pipettes
        Slides in warm
        Slides in ice bath
    - When frozen, the particles in the rocks are fixed in a lattice, that is why the rocks hold their shape. - KS3.C.33
    - Solids are made up of crystals. Crystals are regions of a single lattice orientation. - KS3.C.33
    - When solids freeze quickly the crystals are small. - KS3.C.33
    - The crystals are large because the particles have more time to line up before freezing. - KS3.C.33
    - The crystals are small because the particles have less time to line up before freezing. - KS3.C.33
    - When solids freeze slowly the crystals are large. - KS3.C.33
    - When igneous rocks are formed under the ground they cool slowly so the crystals are large. - KS3.C.33
    - When igneous rocks are formed above ground or in water they cool quickly so the crystals are small. - KS3.C.33
    - The size of crystals affects some of the properties of the rock. - KS3.C.33
  - Lesson 02 - How are rocks broken up? Lesson Plan Lesson Title
    - Weathering is breaking up of rock where it stands. - KS3.C.33
    - Rocks are broken down into increasing smaller particles: Gravel; Sand; Silt; Clay - KS3.C.33
    - Weathering can be chemical weathering, in which rocks are broken down when the particles that make them up are changed. - KS3.C.33
    - Weathering can be physical weathering, in which rocks are broken down when the particles that make them up are not changed. But the forces between the particles are overcome to separate them into small pieces of rock. - KS3.C.33
    - Sedimentary rocks are formed when sediment (little pieces of weathered rock) is laid down in layers under water and then compressed by layers above.
      
      The water between the sediment is squeezed out and the sediment bonds together. - KS3.C.33
    - If organisms fall into the sediment then the rock can take the shape of the organism. These formations are fossils. - KS3.C.33
    - Metamorphic rocks are formed when either igneous or sedimentary rocks are heated under great pressure. - KS3.C.33
- 8C.3
  - Lesson 03 - How do we use the Earth's resources? Lesson Plan Lesson Title
    - All resources come form come from the Earth's crust or the atmosphere. - KS3.C.34
    - Coal contains more energy per kilogram than wood as it is a concentrated form of wood without moisture in. - KS3.C.34
    - Crude oil (and natural gas) is formed when sea creatures (mainly microscopic) are compressed under layers of sediment. - KS3.C.34
    - Coal is a sedimentary rock formed when trees and plants are compressed under layers of sediment.
      
      (The highest grade coal, Anthracite, is actually metamorphic) - KS3.C.34
    - Crude oil can be processed into fuels, chemicals and plastics. - KS3.C.34
    - Metals are dug up from the earth in the form of ores. - KS3.C.34
    - Ceramics are made from muds that are dug up from the earth - KS3.C.34
- 8C.4
  - Lesson 04 - What is the human impact on the Earth? Lesson Plan Lesson Title
    - the efficacy of recycling - KS3.C.34
    - the production of carbon dioxide by human activity and the impact on climate - KS3.C.36
    - A: ENQUIRY: Planning
      
      Aim: To find out how the concentration of acid (rain) affects the rate of reaction with marble chips
    - A: The test for carbon dioxide is to bubble the gas through lime water. If it turns cloudy this is a positive result.
    - Earth as a source of limited resources - KS3.C.34
      - Suggested Activity:
        Circus of objects made of different materials.
        
        Students identify the material and the source - ie Earth or Atmosphere.
        Equipment Required:
        Sand in a jar
        Something metal
        Something plastic
        Something pottery
        Vaseline
        Gas cylinder (CO2 Fire extinguisher)
        FAKE petrol bottle
        Diamonds TO BE COUNTED IN AND OUT
        Gravel somthing
        Fish / Shellfish
        Meat
