Year 3 worked over at The Den with Mr Green in order to investigate what make up soil, linking to our topic of Angry Earth. Our first job was to collect a range of soil using trowels and fill a bucket with it. Then we used a soil sieve to see what was in our soil and wrote a recipe based on what we found. We found lots of different things that included roots, small stones, bits of wood and even wiggly worms. After that we tried to make our own based on what we had found. We flexed our noticing learning muscle to spot what was similar and different between the soil that we had dug up and the soil that we had created. The main difference was the colour and we learnt that soil can't be made quickly but takes a long time for the organic matter to rot down and be ingested and passed out by worms before it is real soil.
We used Starburst sweets in an experiment to help us understand how sedimentary, metamorphic and igneous rocks were made. We used our Reasoning Muscle to explain how sediment is squashed to make sedimentary rock and then how it is put under even greater pressure and heat to turn it into metamorphic rock. Look at our pictures. Can you see the difference between the sedimentary 'Starburst rock' and the metamorphic 'Starburst rock'?
A Day in Pompeii
As part of our topic Angry Earth Year 3 are learning all about Mount Vesuvius and it's devastating effects on the city of Pompeii. The children took part in a game mimicking the pyroclastic flow from the volcano by using tarpaulin to imitate the poisonous gas and how it moved. They also compared different types of rock by creating rubbings of a range of different rocks and comparing the textures and patterns that they produced. We used clay and carved out either an image of a human or an animal and then filled our casts with a mixture of talcum powder and PVA glue to recreate a scene from Pompeii after the volcanic eruption in 79AD.
