Astronomy 天文教育

Big ideas about the sky, read in English and explored with 3D models you can turn in your hands.
用英文讀懂天空的大道理,再用可以親手旋轉的 3D 模型親眼看懂。

Every lesson starts with a question you can check for yourself by looking up. A 3D model lets you move the Sun, Earth, and Moon and see the answer, and an English reading explains it, with Chinese a tap away.
每一課都從一個抬頭就能驗證的問題開始:先用 3D 模型親手移動太陽、地球和月亮,看出答案;再讀一篇英文短文把道理講清楚,中文翻譯隨點隨看。

Each reading comes with vocabulary, comprehension questions, a short quiz, and a classroom activity that needs nothing more than a lamp and a ball.
每篇文章都附生字、閱讀理解、小測驗,以及一個只需要一盞燈、一顆球就能在教室做的活動。
