Tectonic Plates

 Today, year 3 used Oreo cookies as representations of the Tectonic Plates. 

The Earth is made up of many tectonic plates. These plates move very slowly and sometimes they get caught and pressure builds up. Some of the plates have ocean water above them, whilst others include continents. The children identified the three main types of movement which include: Divergent, convergent and Transform.

Convergent plates collide together which causes one plate to go on top of another one. This is how mountains are formed. Sometimes the molten rock rises to the surface making a line of volcanoes.

Divergent plates move away from each other allowing molten rock to erupt out of the opening and when it cools down it forms new crust. 

Transform plates rub against each other and this is what causes earthquakes.

What are the positives and negatives of living near a volcano?

Image
 This week, the children discussed their own experiences when visiting various countries or islands, some children have visited Tenerife, New Zealand, Minorca and they were all surprised to know these places were formed because of volcanic activity.  From our discussions, children realised that a positive reason to live near a volcano is from all the tourism and the money it brings to the area. Furthermore, once the lava cools it breaks down into soil which is rich in minerals resulting in plants, flowers and crops growing well in that area. We also looked at Iceland and how this country uses the heat from under the ground to make Geothermal energy.  One child brought in their atlas to share with the class and Mrs Gregory  it was so interesting.  Fantastic work today year three.

What makes a country a country?

 What a great lesson. The children recapped their knowledge about hemispheres and the Equator. Then, they were introduced to an atlas as well as the index to help them find countries of the world. Using the atlas allowed them to see how countries are different from: size, shape, names and near the oceans as well as the different hemispheres. Then the watched a short clip which explained what a country needs to identify as a country. The children decided that La country needed a flag, currency, borders, a government, religion, language, passport, ruler. mountains  and rivers.

Exploring Skara Brae

Image
 170 years ago, on an island off the coast of Scotland, a storm came and blew away a large amount of sand... Below the sand, historians were shocked to find a Stone Age village! Year 3 started to explore the artefacts that tell us about what life was like for Neolithic people. The evidence suggests that this people ate fish, made jewelry, kept warm by a fire and even had dogs! Archeologists found ancient dog poo! Yuck. Year 3 were curious to find out why people abandoned Skara Brae. Why would they leave their cosy town behind? Look below to see some of the ideas that Year 3 came up with.
