从本质上来说，科学家就是一群热衷于探究的人。他们提出问题，寻求答案，收集证据以及设计实验。他们致力于回答“是什么”以及“为什么”。
美国培生教育出版公司著的《科学探索者（英文影印版）》这套书生动有趣，精彩纷呈，充满了各种学习的机会。令人兴奋的最新科学内容，赏心悦目的图片以及丰富多彩的探究活动……所有这一切都将激发学生的想象力和求知欲，让他们完全沉浸到科学的世界中。
《人体生理卫生(英文影印版)》为系列中的一个分册，它把课本里高深晦涩的理论通过简单的实验深入浅出地描述出来，让人既有读下去的意愿，也有亲自动手做一做的冲动。本书并不只注重单个知识点，而是把各个知识点连成链条，并对概念和规律进行拓展，联系实际生活，应用生活化的情景作为学科情景，使之鲜活地展现于书本之上，以加深学生对理论的理解。
