This week we learnt about Geology and learnt that there are many types of stones and one of the stone is ‘igneous rock’ and friends and I made edible ‘igneous rock’, Hokey Pokey! We needed sugar, golden syrup and baking soda to make it. Firstly, Jasmine brought the sugar and syrup into a pot and Cherry simmered it over a low heat for us. We quickly removed it when it changed to liquid and added baking soda. It was getting gold when we stirred it. Finally, we pour into a greased tin and waited until becoming cold. The process of cooling hokey pokey was similar with solidification of magma from volcano. It was very fun and useful activity to understand the process of volcano and it can be a sweet and useful activity to children too.
The second activity was Toasted Sandwiches. We simply made sandwiches with breads, marmite, cheese, and then toasted! This toasted sandwiches was an example of rock formation as the bread being the Earth’s crust, and the marmite and cheese showing as and lava from a volcano eruption. We can explain to children how layers are formed when pressure or heat is occurred through this activity.
Reflection on Geology
Learning the topic Planet Earth or Geology for children was interesting. It was an opportunity for me to realise about the earth in child’s point of view. The topic focused on the layer of the Earth, rocks and many other components that make up planet Earth such as ‘inner core’, ‘outer core’, ‘mantle’ and ‘crust’. These terms may seem hard to children but teaching about geology would be fun if we have lots of activities with various resources that portray the idea of the earth. A sandwich activity can be the one of the activities of rock formation as it can be done easily in a centre of at home with children. Also making hokey pokey or cookie would give children the opportunity to learn the difference between sedimentary, igneous and metamorphic rocks and how they are made. Personally I was very interested to learn about the rocks even though I knew those already. This is because the activity, Hokey Pokey. When I was young I often made and ate it but I have never thought about that is relevant to Geology, not even once. However, now I knew that this hokey pokey can be an activity of geology and this was very impressive. In addition, I learnt about disasters such as earthquakes and volcano, and also the process these disasters. I think these are important to remember to teach children about geology because children would not able to understand why and how these disasters occur, therefore I as a teacher need to share the information in simple, easily understood ways, and do more interesting activities that can explain about earthquakes and volcano then, children would be able to grasp.
Resource for Geology
This activity is about making Earths Crusts, Core and Craft with various colours of play dough. Children can use different colour for each different step of core, mantle and crusts of the Earth. For example, Red is inner Core, Orange is outer Core, Yellow is mantle, brown is curst and blue and green is water and land. Then children would recognise the earth more easily with colours. When children finally made the earth with some land shapes, they can cut a wedge from of the earth in model form! Children would be amazed about their work and that is the real form of the Earth. This is why I chose this activity for young children.
