The answer is, shepherds pie! 😄
I had planned to do other activities with our soil in the garden, but it was pouring with rain, so I had to change my plans.
I decided to get the group to make a traditional english dish ‘shepherds pie’ for dinner…
And what has this to do with ‘earth’ ?
Everything in this recipe is either grown in the earth, or is food which is grown in the earth, used to feed the animal in the recipe (cow). 😃
Earth (soil) is very important to us!
This week we learnt about what a sedimentary rock was, how it becomes one, and what it is made up of.
We took clay, sand, gravel and water, and put them in a lidded jar, shook them up, and watched them settle, to see how sediment settles in the real world…
We will observe this again next week.
We also made a mixture of flour, sand, salt, water and oil, to make a dough, as our ‘rock’, to which we added different coloured ingredients (cocoa powder, pepper, paprika and tumeric), which we then squashed together, to show how our sedimentary rock is layered.
We talked about how rocks get weathered (through sun, ice and wind), and eroded through being moved and broken in various ways. Then how the tiny rocks settle on the land or on the sea bottom, and eventually become new rocks – sedimentary rocks – natures way of recycling.
We also continued adding the dissolved alum and food colouring to our egg geode experiment from last week… 😄
What is an igneous rock? That was the question that was asked .
I explained that an igneous rock was essentially a volcanic rock, either having cooled under water, or in the air.
After observing such rocks, we did an experiment with sugar dissolved in water, to see how differently a mineral will cool in air and in water.
One mixture we put in a tray in the freezer (water), and left for fifteen minutes – and it came out flat and shiny, like obsidian rock, and those volcanic rocks that are cooled under water.
The other mixture we left to cool in the air, to observe the following week. As expected, in hardened in a bumpy ‘rocky’ fashion, with air holes, not unlike basalt, a volcanic rock cooled in the air, which we had also observed (above).
The kids then drew their own versions of the volcanic flow and rock reaction…
The older group in English Club (12 – 14 year olds) have now started a new topic : Our Amazing Earth – which is essentially about rocks and stones.
We started the topic by asking the question “What is Obsidian?” – a word that this age of boys often hear from the computer game ‘Minecraft’.
Obsidian is a volcanic rock, that has been cooled under water, and thus gives it a flat shiny look…
After observing this rock, I asked the kids if they knew what our earth was made up of.
I then asked them to think about this, and make me our earth and it’s layers, from playdough….before explaining to me what these layers were….
I told them we were going to do the topic of geology, and where the word came from…
…and we then went on to discuss our earth’s treasures. What materials come from the earth, and how we use them in every day life…..
But how do we get these treasures?
Then the kids ‘mined’ chocolate chips out of their cookies! The chocolate chips were the treasures, the cookies were the caves. For every whole chocolate chip they managed to mine out, they recieved 5000kr, but each time they damaged the cave, they were fined 2000kr…. 😉
We are using this book as our basis for explaining about the rock cycle…
It was a long time a go I wrote.
I went to England to see a sick friend, and every time I visit, my heart breaks a little, and I feel a little sad for a while afterwards…
But these are some pictures I took, on my walk up to the train station, on my way to the hospital.
I miss England every time I visit, and one day I hope to move back.
When I visit my friend, I stay with his parents, in what used to be his own ‘penthouse’, and I always take a photo out of the window while I’m there….
Two seperate mornings. One rainy, one sunny.
Until next time……
