Hi students! Today I want to talk about an invention. There have been some great inventions. Almost everything was an invention at one time, like the telephone and the car and the airplane.
今天我們來聊聊發明。世界上有很多大發明，像是電話、汽車，還有飛機。
Most inventions are made by adults. But today, I want to talk about a cool invention made by some kids in Canada. Their names are Liam and Fraser.
很多東西都是大人發明的，但是今天我要講兩個加拿大的小孩發明家，叫做 Liam 跟 Fraser。
One day, Liam was taking sailing lessons and fell into the sea. Luckily, he was wearing a life-jacket. He was safe because of the life jacket, but Liam was really cold in the water.
Liam 在帆船課的時候掉進海裡，幸好他有穿救生衣，但是水裡好冷！
That freezing cold water gave Liam a great idea. He worked with his friend Fraser on an invention. What was their invention? They invented a heated life jacket.
這給了 Liam 一個好點子，他跟他的朋友 Fraser 發明了一個發熱救生衣。
They put a special chemical in the life jacket. When the chemical touches water, it gets hot.
救生衣裡面有化學物質，碰到水就會加熱。
To test their new life jacket, they jumped into the ocean. But they used too much of the chemical the first time, so they got a bit too hot.
為了測試他們的發明，他們跳進海裡面，結果因為化學物質太多，衣服變得太燙了。
So, now they don't use as much of the chemical in their life jackets. And they won a science award for their great invention!
他們減少了化學物質的用量，後來贏得了一個發明獎！
Maybe some of you smart kids will invent something great, too! Good luck!
