Science - How do rocks change?

 Today we had great fun making a range of rock types out of 'Maoam' sweets. First, we broke up our sweets into pieces, creating our starting point - rock sediments. We then built our sediment into a wall of layers and pressed down gently - making a sedimentary rock. We then placed it inside our sandwich bag and added lots of heat a pressure, changing the rock into metamorphic rock! We finally heated our rocks in the microwave, melting them into magma, before letting them cool into a very dark, crystalline igneous rock!

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 are the features found in a volcano?

 What an amazing lesson, year 3. First, the children recapped the layers of the Earth from last lesson and how the tectonic plates move. Then, the children watched a small clip with Dr Bonocs, as he discussed the different features that can be found inside a volcano. The children were amazed watching how quickly a pyroclastic cloud can move and the damage it causes. Once the children understood the different features there was a model of a volcano some of the children found interesting and they were able to describe the features.  The last part of the lesson located the Ring of Fire in the Pacific Ocean. More than 75% of the world’s volcanoes and earthquakes happen here.  Have a look at the beautiful painting one of the children made of a volcano. Mrs Gregory was very excited to see it and share it with the class.

What comes out of a volcano?

Image
 This week only one class took part in this lesson as all of Year 3 went on a Geography Fieldwork trip to Moors Valley.  In the lesson the children identified what came out of a volcano and then they used Google Earth to walk around two volcanoes. Here, they identified the features of a volcano from the last lesson as well as describing what they could see as we walked around the volcanoes.
