This term, our Science learning will focus on rocks. The curriculum states, the children need to be able to:

  • Compare and group together different kinds of rocks on the basis of their appearance and simple physical properties. 
  • Describe in simple terms how fossils are formed when things that have lived are trapped within rock.
  • Recognise that soils are made from rocks and organic matter.

Investigating properties of rocks:

As part of our science learning, we have been investigating the properties of different rocks. We firstly tested the hardness of the rock, the acidity, the appearance, and finally (and our favourite) the permeability. We were fascinated to see how quickly some of our rocks absorbed the water!

Starburst Rock Cycle

We looked at how the rock cycle works:

  1. We cut our starburst into pieces to represent the sediments of the rocks.
  2. Sedimentary rocks are formed by pressure over time - we had to squash them to get the sediments to stick together.
  3. Metamorphic rocks are formed by heat and pressure - we had to kneed and press the sweets together to get them to mix together. At this point, we saw how the colours mixed together.
  4. Igneous rocks are made with extreme heat (e.g. volcanoes). We placed our metamorphic rock (starburst) into the microwaves and heated them, until they completed melted into a liquid. We left it to cool, before popping it out of the bowl and all of the colours had mixed. There were no visible layers.
