In Math, we have started learning about directions and mapping. Today we had a treasure hunt. We had to read clues and find our way to the 'treasure'.
Olivia: Today I'm going to talk about cars. Long, long ago they didn't have cars in Korea. They had chariots and people carried them. And then they had cars. And now they have unmanned cars.
This boat is made of wood. A long time ago people just made boats by cutting trees and tying the wood together. And then they would go fishing and things in Korea. Now they ride in boats. Now the boats in Korea we drive and there are two floors on the boat. If you go a long distance, you can go and sleep downstairs and someone else can drive. There are lots of motorised boats now.
To find out what life was like in our parents' and grandparents' lifetimes, we created questions and interviewed our parents and grandparents. Then we presented our interview results to the class.
We found several similarities and differences between life now, when our parents were young and when our grandparents were young.
Amelia, Olivia and Holly have been learning about the amount of plastic in the ocean and wanted to take action. They brought in a book from home called "Captain Green and the Plastic Scene" and asked if they could share it at assembly. They read the book and then talked about products people could use that do not contain plastic and showed some examples of artwork that could be made from recycled materials.
Maria: Prosthetic limbs are artificial arms or legs attached to the body after someone loses an arm or leg.
The first record of a prosthetic limb is the story of a Persian soldier in 484 B.C. who lost his foot when trying to escape from his enemies, and then made himself a wooden foot.
The oldest surviving prosthetic limb was a copper and wood leg found in Italy. It was about 2,300 years ago. It was kept in a museum in England until it was destroyed in World War II.
Most prosthetics in the past were made for soldiers who lost their limbs in battle.
This is an old prosthetic arm made from metal from the 1500's.
Prosthetic limbs in the olden days were usually made from wood or metal and attached to the body with leather straps. For many centuries people used peg legs made of wood and hooks for arms. But these types of prosthetics did not move like regular hands and legs.
Now prosthetics have become much more advanced. For example, runner athletes without legs can use cheetah blades, which are artificial legs shaped like sleighs. They are made of carbon fibre which is very strong but also light. It also acts like a spring which is needed to make running easier. Runners using cheetah blades can run just like you and me.
Now we will watch the first video.
Maria: Prosthetic arms are also getting much better. Scientists have even invented ways to connect the prosthetic to the brain so that the person can control it with their brain. In this way the prosthetic arm can behave the same way as yours and mine.
I also found this interesting video of a boy who made a prosthetic arm out of Lego.
Maria: My research was interesting because I learnt something new. I had never seen the cheetah blades before and I thought it was cool that even if you have a disability you can still play sports and move like everyone else.
Ms Leah: I also saw a video on Facebook this morning about prosthetics. Would you like to see it?
Charlie brought in a caterpillar and a caterpillar in a chrysalis. This week a butterfly emerged from the chrysalis!
Yuuki: Before in my grandparents' lifetime, they used an abacus to do Math. You would do 5 and then plus 4 equals 9.
And in my mom's life they used a calculator to do Math. Like 7 plus 5. You can see how much it is.
ow we can use an iPad or phone. A screen. We can use this like Siri now.
Siri, what is 9 plus 9? Siri will tell you.
What time is it, Siri? Here is the clock.
We are a class of Grade 1 students at an international school in Singapore hoping to share our learning with you.
