Where do diamonds come from?

In maple this week we have been answering our question…Where do diamonds come from?

We have carried out some investigations to learn more about how they form. Before half term we had looked at how rocks are made and how our earth has many different layers.

How do diamonds or crystals form?

John: I learnt how to make fake diamonds.

Nataniel: I was interested to learn that diamonds grow on rocks.

Jayden: We put some Alum powder and hot water in a mug. Next we put a pipe cleaner on some thread and tied it to a pencil. We hung the pipe cleaner in the mixture and left it for 24 hours.

           

The next day there were crystals in the mug.

 

Matthew: I was interested to learn that lava helped to make diamonds.

Joshua: Diamonds don’t come out pretty and shiny or shaped, they come out bumpy and rough and they are cut using other diamonds.

 

Different types of rock

We used starbursts to learn about the rock cycle.

Dilmara: we opened the sweets and chopped them up and squished them together. We put it in a bag and squished them up even more. Next we melter them and waited for them to cool. The sweets were now brown and hard.

First we cut the rocks (sweets) up. This created sediment which in nature is created by wind, rain and erosion (matthew)

The sediment comes together and is compacted to for sedimentary rock.

 

Next with more squishing and some heat the sedimentary rock becomes metamorphic rock. (jayden and Matthew)

The rock melts with lava (Harvey) and it becomes igneous.

Some bits broke of of the igneous rock and we saw that there was more sediment so we learnt that the process can start all over again.

Natural and man made rocks

Zarah: I enjoyed finding stones. We looked for man made and natural stones.

We went out into the playground and found that not all stones and rocks are natural. We found some things such as bricks, and the road and paths are made by people. We also found lots of natural stones outside and washed them. We saw that there were lots of different types of stones with different colours and patterns in.

Why do volcanoes erupt?

In Maple class this week we have asked the question… “Why do volcanoes erupt?”

We watched videos of volcanic eruptions and talked about where the name volcano comes from. John was very excited to learn that it came from a Roman god called Vulcan who was the god of fire.

We then coloured and labeled a diagram of a volcano.

We used Plasticine to create all the layers of the earth. We started by making the core and then wrapped it in the outer core and then wrapped it in the mantle. Finally we added the earths crust with sea and land. We then cut them open so we could see all of the layers.     

Defying gravity with bottle rockets

In maple class we asked the question: How do you build a rocket?

We researched rockets and watched rocket launches and then designed and made our own bottle rockets.

We filled the bottle with a little water and then used a pump to increase the air pressure then…..whoosh!!!!

We learnt that if we want to launch a rocket we need to beat gravity. Gravity pulls things down and we needed the air pressure and the water jet to push the rocket up.

We then drew a diagram of our test and labeled it.

Meet the brain!

In maple class we asked the question…What do different parts of our brain do?

Me made our own brain hats and explored what different parts do.

We learnt that one part of our brain in the middle controls our breathing and our heart beating Another part helps us make sentences. Another part stores the words and a bit on the top controls our movement.

We are going to explore more of the parts and jobs of the brain over the next week.

Sowing seeds!

Throwing sycamore seeds into the air
making our own helicopters

We found sycamore seeds in the tree circle and threw them into the air and watched how they worked like helicopters to float to the ground. We made our own helicopters out of paper and watched how they span to the ground. We learnt that sycamore trees use this method to spread their seeds to grow new plants.
