我們希望透過2D動畫、電子書和一些實驗影片來增加國小高年級對於知識的興趣，並把在學校學會的東西展現出來，而我們想介紹關於槓桿、滑輪、輪軸的原理。
We hope to increase the interest of senior elementary school students in knowledge through 2D animations, e-books and some experimental videos, and to show what they have learned in school. We want to introduce the principles of levers, pulleys and axles.
