  3. Unit 3D: Rocks and Soils Some useful words Slate – Marble – Chalk – Granite – Sand – Clay – Texture – how the surface of a rock would feel Absorbent – a rock that will soak up water The names of different rocks Unit 3D: Rocks and Soils

  4. Unit 3D: Uses of Rocks Uses of Rocks Unit 3D: Uses of Rocks: L.O. 1: N.C.

  5. Unit 3D: Grouping Rocks Grouping Rocks For each of the rocks available make as many observations as you can. Record the details in a table Unit 3D: Grouping Rocks: L.O. 2, 3: N.C.

  6. Unit 3D: Testing Rocks Testing Rocks We can test rocks to compare them 1) Rubbing test – we can rub 2 rocks together to see how easily they are worn away. Take 2 rocks of the same type and rub them together. Collect and examine any particles that are formed. Rank your rocks in order of ease of wearing away. Which rock is the hardest? 2) Permeability – absorption test. Drop small amounts of water onto each rock to see if any is soaked up. You will only need very small amounts of water, note how quickly the water is soaked up by each rock. Unit 3D: Testing Rocks: L.O. 4: N.C.

  7. Unit 3D: Different Rocks different uses Different Rocks different uses Granite Marble Slate doesn’t wear away weather-proof is attractive Unit 3D: Different Rocks different uses: L.O. 5: N.C.

  8. Unit 3D: Where are all the rocks? Where are all the rocks? Unit 3D: Where are all the rocks? L.O. 6: N.C.

  9. Unit 3D: Observing Soils Observing Soils Use the equipment provided to separate the soil particles, write down any observations you can about each soil sample Unit 3D: Observing Soils: L.O. 8, 9: N.C.

  10. Unit 3D: Water flowing through soil Water flowing through soil Why do puddles stay in some places longer than others? Unit 3D: Water flowing through soil: L.O. 10, 11, 12, 13, 14: N.C.

  11. Unit 3D: Different Rocks, different soil Different Rocks, different soil Chalk Clay Unit 3D: Different Rocks, different soil: L.O. 7: N.C.

  12. Unit 3D: Water flowing through soil …cont You are to investigate the relationship between type of soil and how easily water flows through the soil. What will you measure? How much water will you use? How will you keep the test fair? Record your results and put the soils in order Unit 3D: Water flowing through soil: L.O. 10, 11, 12, 13, 14: N.C.

  13. Building Etc. Rub Variety of uses Particles Absorbency (permeability) Test Rocks Colour Group according to characteristics Texture Rocks and soils Hard Granite for steps Depend on rock Slate for roofs Chosen for characteristics Soil Not permeable Sieved Marble for statues Water flows easily through some soils Looks good Unit 3D: Summary Unit 3D: Rocks and Soils: Summary
