Today we learn about force.
今天我們學到了有關力量的概念
We are testing to pull the car with a rope. One, Two, Three.....What will be happened?
我們測試著用繩子拉小車車,123...看看會産生什麼結果呢?
If the car can't move, you will spend a lot of force for pulling.
如果車車不動,前方拉者就得花大的力量
Perhaps the car is lighter , you don't need to spend much force for pulling.
假如車上的重量較輕,你將不需要施更多的力量
Eric is easy to pull Zeo because Zeo is lighter than him.
A~看來Eric不費吹灰之力就可以輕鬆拉動Zeo
Switch each other 交換再試試...由此可知, 施力的大小與乘載物重量是有絕部份關係的
Tr. you must help me to pull becasue someone is too heavy.
老師你就先幫幫我,我下次一定會多吃菠菜啦!!!!
Who will be next team?
下一組老牛拉車換誰呀?
We pull not to be straight way it might be hard to move the car.
換個方式,轉彎是不是比走直線更加費力呢?
One,Two, Three...Go!!!! Why can I pull easily?
123....ㄣ~~~~~為什麼我拉不動咧??
Oh~ I got it!!! This way is right.
喔~我知道了,原來是方向錯了,順著拉比逆著拉更省力唷!!! Ya~
Next, we are talking about pushing.
接著,我們試試"推"的施力概念
The iron carbinet is much heavier so we have to push it with three people.
因為鐵櫃比較重,沒有三個人是很難輕鬆推動它........呼!!!!
All the girls and two boys, a girl which tema is easier to push?
三個小女孩難道會比二男一女更來的簡單推動鐵櫃嗎???
Today we try many ways to know about pulling and pushing.
今日"拉.推"主題,我們發揮在實物當中,除了有趣好玩之外,更重要的也讓孩子們對"施力"的多了一層概念
