在生活中，你是否也察覺到這樣的現(xiàn)象：樹上的果實熟了會自己掉到地上；氫氣球會自己飛向天空；天冷的時候可以通過搓搓手取暖……這些都是存在于我們生活中的“力”，雖然看不見摸不著，但卻能讓我們真真正正的感受到。1687年，英國著名物理學家牛頓因為一顆掉落的蘋果發(fā)現(xiàn)了萬有引力。在距他三百多年后的今天，我們的孩子們也紛紛在外教課上化身小小科學家，在純英文課堂中學習和探究生活中的“力”，雙管齊下，成為一個個科學與英語兼顧的小達人。
在探究生活中的“力”的課堂中，外教Colin和Mike在英語教授了孩子們一些力學的理論知識后，還進行了各種各樣的實踐活動來輔助孩子們的英語科學學習。在學習用測力計測量不同物體的重力時，外教引導孩子們用課堂所學的關(guān)鍵詞匯來描述自己的實驗過程。當Colin提問孩子們“一個蘋果重多少牛頓？”時，他們爭先恐后地回答著“我的蘋果重3牛！”“我的蘋果是2.5牛頓！”。學習浮力時，孩子們輪流嘗試了將氣球按壓在水中。當孩子們感受到水向上頂住他們的手時，他們脫口而出地道的英語：“我感受到水中的浮力了！”學習摩擦力時，我們用小車滑下斜坡的實驗帶孩子們測量了小車分別在地板、毛巾、和砂紙上能行駛的距離，Mike將本節(jié)課的關(guān)鍵詞“pattern（花紋）”、“rough（粗糙的）”、和“smooth（光滑的）”等都和實驗過程緊密結(jié)合在了一起，讓孩子們在做實驗的同時反復練習這些關(guān)鍵詞匯。實驗結(jié)束后，孩子們結(jié)合課堂所學內(nèi)容向Mike展示了他們自己設(shè)計的適合踢足球的運動鞋，讓我們欣喜的是，孩子們都能獨立又流利地用課堂所學關(guān)鍵詞和句型來介紹自己的小“發(fā)明”了。
為了讓孩子們更好地記住有關(guān)“力”的知識點，Colin還自己寫詞譜曲了“重力英文歌”。一節(jié)節(jié)探究生活中的“力”的課堂都在孩子們嘹亮的歌聲和純真的笑臉中結(jié)束，但是，結(jié)束的僅僅是課堂，孩子們渴望探索科學的熱情以及用英語表達自我的自信將陪伴他們走出課堂，走向今后美好的時光！
Have you ever noticed some phenomena in our daily life? An apple will fall down to the ground when it is ripe. A Helium balloon will fly to the sky if there is nothing holding it. Rubbing hands help us keep warm in winter. These are all things that happen when forces act on us. We can’t see force, but we can feel it. Isaac Newton, a famous British Physicist, found gravity in 1687 AD because of a falling apple. Three hundred years after his discovery, our foreign courses, which provide children a chance to explore and learn forces in a pure English environment, equip our children with both science and English knowledge.
Besides instructing basic theories of forces in English, Colin and Mike prepared kinds of experiments as a supplement in students’ study. When studying gravity, we used a force meter to measure the weight of different objects. Meanwhile, we encouraged our students in using key words to describe their experiment procedures. When Colin asked them “What is the weight of an apple?”, they were all answering him full of passion “My apple weighs 3 newtons!” “Mine is 2.5 newtons!” As studying upthrust, children could feel the force when they were pushing a balloon into the water. They got very excited feeling upthrust and kept repeating “I can feel upthrust in water!” in class. We also did a fair test of a car running from a ramp on different surfaces, including floor, towel, and sandpaper in order to show students about different frictions. Mike combined many key words (pattern, rough, smooth etc.) into the fair test which would offer our students a more impressed memory of the key points. After the experiment, students shared principles of their new invention of shoes for playing football. It was such a big surprise for us that the students could introduce their inventions in English independently and fluently using the key words they just learned from class.
Teacher Colin also wrote a song about gravity to help our children memorize the knowledge that they learned from class. Every class of forces ended up with children’s resonant singing and smiling faces, but their enthusiasm about exploring science and learning English would not end. Their passion to scientific sensibility and confidence in English expression will be brought out of the classroom, and lead them to a bright future.
