Today, I had some astronomy activities, which was very interesting. For this activity we used a lamp and two different sizes of polystyrene balls to represent the sun, earth and moon. We painted on two polystyrene balls so we can recognise easily. We draw the earth on big polystyrene ball and we painted cold on small polystyrene ball so it can be seen as the moon. We connected the earth and the moon with stick, and spun it around the lamp, the sun. When the lamp created shadows, we could see moon phases and different eclipses. I thought this could be done with children to show the rotation and tilt of the Earth, of course the orbit of the moon around the Earth and that around the sun.

 

Activity 2

The second activity was about phases of the moon. In the room, there was a board, which was stuck with the different shadow position of the moon. While some friends hold the board up, I could stand in the middle of the board and can see each lunar phase, from a full moon to no part of the moon visible at all. This was very simple way to learn about the rotation of the moon.

Reflection for Astronomy

I thought I already knew about the relationship between the sun, moon and the earth. However, I had learnt so much information in child’s point of view that I always kind of took for granted. This topic, Astronomy in early childhood can look at day and night change, seasons, climate and many other components beyond planet Earth. Children would be amazed about knowing the Earth’s solar system, including the sun, moon and each planet. While I was doing the activity about the Earth rotation, I wondered, could children really believe this even they could not feel it but I realised that I could not feel it either but my head already knew that the earth is turning even now. Children are active learners so if the teacher shows visual examples and encourage them to involve in their learning, children would learn naturally about the earth, the sun and moon. In addition, talking about the seasons change, and day and night could be a good way to teach about the rotation and tilt of the earth. We can talk about how solar eclipses and lunar eclipses occur in different circumstances through the activity that I talked above. I was really happy to learn about this topic because I learnt many things and I am excited for teaching children about astronomy because there are so many things to talk with young children.

This activity is about making a model of solar system with the sun and other eight planets. I chose this activity for astronomy resource because this would be a fun and useful activity to teach children about space and solar system in the centre. By using different size and colour of planets, children can learn difference between each planet; furthermore, they would be able to create their own solar system. Through this activity, children can explore their excitement about the topic and I believe this activity would develop children’s knowledge of solar system.

Geology

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.

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.
