VOLCANOES and EARTHQUAKES SPRING 2017      volcano200

 

 

 

This half term, we have begun learning about Volcanoes.  We watched a film about the layers of the Earth and created our own diagrams:

We have labelled cross sections of volcanoes and used glossaries to find out the meanings of technical words.  Take a look at our display and the glossary that we made:

As part of our topic, we studied rocks and soils, in science.  We found out there are three types of rock: metamorphic, igneous and sedimentary.  We used chocolate to make some sedimentary rock.

First rocks break and crumble due to weathering:

This turns the rock into small pieces, called sediment, which are washed away by rivers and streams.

Eventually, the sediment arrives at the sea, a lake or part of a river and the pieces of rock begin to settle to the bottom:

The sediment begins to build up in layers.  After millions of years the weight of the layers squeezes out the water and turns the sediment hard.  It is now sedimentary rock:

Take a look at some of the layers that we found in our sedimentary rock:

We looked at paintings of Mount Fuji by the Japanese artist, Hokusai.  We used sketching and water colour paints to re-create some of his paintings.  Take a look at our brilliant work here:

We read information about what earthquakes are and why they happen.  We found out that earthquakes are most likely to happen where tectonic plates meet.  Take a look at what could happen in an earthquake:

Here is a film of what happened!!   Earthquake simulation
