Bob Bonnet&Dan Keen著的《我們身邊的能量知識(英漢對照雙語讀物)》介紹的一些科學概念,對學生們理解*深奧的科學原理會有很大幫助,所設置的科技活動將會開發學生的科學研究技能,而這些技能是我們這個繁雜的社會所必不可少的。科學研究技能包括:對物體進行分類的技能,分析觀測結果的技能,清晰思考的技能,準確記錄數據的持能,以及按照正確方示處理記錄值的技能。本書中的許多科技活動是作為“我們身邊的科學知識”來設計的,以示其與“書本科學知識”的區別。“我們身邊的科學知識”,顧名思義就是指在你身邊的科學知識,即你們家裡、你們街區、你們學校裡的一些科學知識。 本書采用“英漢對照雙語讀物”的形式,目的在於讓學生們了解如何用英語來描述我們周圍的世界,如何用英語來表述我們所學過的一些科學知識,以及如何用英語來講述我們的日常生活、學習和科技活動。
