TERM 4 THEME: HOW THE WORLD WORKS
TERM 4 THEME: HOW THE WORLD WORKS
This term, we will be following different lines of inquiry to help us to find out about how “Forces of nature can sometimes transform the physical world..”
The lines of inquiry we will explore are:
Why there are different types of rock and pebbles (causation)
How the volcanic eruption affected life in Pompeii (change)
Volcanoes around the world (connection)
In geography, Year 3 followed instructions to create the different layers of the earth using play dough whilst finding out information about each layer.
Step 2: Carefully we rolled out the yellow play dough to create the outer core so we could wrap this around the inner core.
The inner core is mostly made up of iron with some nickel and is over 4000˚C.
Step 3: The mantle was made by rolling out orange playdough followed by wrapping it around the outer core.
The mantle is 3000 km thick and is extremely hot rock that has the consistency of treacle.
Step 4: The crust was made by rolling out brown playdough followed by wrapping it around the mantle.
The crust is a thin outer layer of cold, hard rock that covers the Earth and varies in thickness from 10km to 90km. The crust is not even and is made up of pieces which overlap the entire planet. These pieces are called tectonic plates.
Step 5: We used blue playdough to create the oceans.
Step 6: We used green play dough to show the continents around the world.
Step 7: Finally we cut the playdough model in half to see all the layers of the earth.
Year 3 have thoroughly enjoyed our science workshop on rocks and soils with Mr Bonner. We discussed the properties of rocks. We scratched rocks with spoons to test the hardness of rocks, from softest to hardest. We used microscopes and magnifying glasses to observe the rocks. We identified which rocks had crystals and those that didn't have crystals. We sorted rocks from smoothest to roughest.
After break we discussed the different types of rocks (sedimentary, metamorphic and igneous rocks). We created a model river to show how sedimentary rocks are created. We then added a fossil to our river models to show how fossils have been created.
We then handled different fossils: a trilobite, an ammonite, a coprolite (dinosaur poo), a devil's toe nail, an echinoid, belemnite and an Ichthyosaur.
Just before lunch we created our own fossils by wrapping a piece of plasticine around the outside of a shell pressing carefully to create an imprint of the shell. We made sure we created a dish shape so it would sit on the table. We then created the plaster by mixing 3 teaspoons of plaster and then added some water until it was the consistency of toothpaste. We carefully mixed the plaster and carefully spooned the plaster into our plasticine mould.
After lunch we had the opportunity to look at many different minerals such as Iron Pyrite, Tigers eye and Amethyst.
We then took part in another experiment which showed us how sedimentary rocks become metamorphic rocks.
Our day ended with a bang! When we looked at different types of volcanoes and learnt how igneous rocks are made.
World Book day 2023
Well done Ash and Maple, you all looked AMAZING!
In art we have drawn fossils from observation looking carefully at the line, shape and texture of different fossils. Then we selected our favourite fossil to create a printing block by carving out our design onto polystyrene.
