Our topic is rocks, fossils and volcanoes. We have been on a trip to Charmouth to collect fossils. We have made posters in our topic books about rocks and we have created information leaflets about rocks and fossils.
We have learnt lots of interesting facts. There are three types of rock:
- igneous – these are formed by molten rock above ground which takes thousands of years to cool. Every rock starts as igneous.
- metamorphic – these are formed by pressure and extreme heat.
- sedimentary – these have lots of layers pushed down on top of each other. This is the only type of rock in which you will find fossils.
Mr Joy layered sweets in a glass jar to demonstrate layers of different types of rock and how they form. He added melted chocolate to see how fast the molten rock would have dried and become solid. We found this a useful and interesting experiment.
We will be learning more information about volcanoes. We are enjoying this topic! Here are some photographs of our work so far (click to enlarge):
