How are deserts formed?

 After recapping the difference between weather and climate the children looked at pictures of various deserts. Some of the deserts showed pillars, mushroom rocks, salt basins and ridge rocks. One thing they all have in common (except for salt basins) is they are formed from erosion. Erosion is when pieces of the Earth’s surface are moved from one place to another by water, water or wind. Erosion happens very slowly. Thus, the rocks, sand and wind wear away the land. 

Salt basins (Atacama Desert) are formed when water evaporates and leaves salt behind.

What is Europe?

Image
 This week, the children have been using atlases to identify where Europe is in the world and the countries which are found there. This is what the children identified.  Europe is a continent that we live in and it is one of the smaller continents.  Parts of Turkey and Russia can be found in both Europe and Asia?  Some of the countries in Europe are land locked. The largest country is Russia and the smallest country is Vatican City. Italy is shaped like a boot.  Lots of people live in Europe. Europe is in the Northern Hemisphere.  Well done year 4 some amazing conversations and observations.

Let’s visit Antarctica

Image
 Today the children went on a virtual tour of Antarctica: the coldest desert and nearly twice the size of Australia.  They learnt how scientists need to plan weeks before they embark on their journey. They need at least 30 pieces of equipment to ensure they have everything they need as there are no shops. once there they stay in research stations where they have everything they need to survive such harsh conditions. When the weather is good they go out on many expeditions as well as researching many subjects such as the magnetic field.  A big thank you to one student who brought in pieces of a salt basin from Portugal which we learnt about a few weeks ago. So light to hold and although the children were told not to taste them, one did and confirmed it was very salty!
