Rocks and Soils Workshop Content
- Opening of the workshop; with a brief introduction to the Earth as a whole we will look at the core, mantle and crust to explain that wherever you are on the earth`s surface there are rocks beneath you.
- How rocks are made up of minerals: to explain this, the presenter goes through the motions of baking a chocolate chip cookie which are made up of several ingredients. These ingredients represent the minerals found in rocks. Once all the ingredients are assembled, to finish making the cookie you need to cook it in an oven (heat). As with minerals, you need to provide heat, and the only source which is at the right temperature to melt the minerals is deep within the Earth.
- Handling Mineral: Class will look at some minerals (quartz, rose quartz, calcite, etc.).
- Discuss Rocks: Class will look at the three different classifications of rocks (sedimentary, igneous and metamorphic).
- Igneous: briefly look at volcanoes, explaining about different types of lava, magma and granite.
- Volcanoes: Samples of lavas and granites will be shown to the class.
- Experiment: Can rocks float? A demonstration to show that a piece of volcanic pumice can actually float on water.
- Look at what igneous rocks can be used for: buildings, decoration and road construction.
- Sedimentary rocks: Explain briefly about weathering, transport of sediments and deposition of sediments in the sea to form new sedimentary rocks. Samples of sandstone and limestone will also be shown to the class.
- Different uses of sedimentary rocks: for example limestone can used for construction and the making of cement.
- Metamorphic rocks: briefly discuss how original sedimentary/igneous rocks can be changed into metamorphic rocks by heat and pressure.
- What can Metamorphic rocks be used for? Marble for statues, ornate building work, etc.
- Practical: class looks at varieties of rocks to identify their basic properties, such as; what is its colour, is it made from grains or crystals, is it soft or hard and is it porous? For this exercise each pupil will have a hand lens and a worksheets to complete.
- Rock samples include:
- Soils: look briefly how soils are made and look at some examples.
- Fossils: How they are formed, what type of rock they are usually found in and what do they tell us about the past.
- Class shown varies examples of fossils: (trilobites ammonites shells) including dinosaur bones and teeth.
- Practical: Fossil rubbing (varied selection of different types of fossils are used).
- Quiz: this is used to re-in force the various topics of the workshop.
