我们常常认为的科学是基于化学实验或者是记住生物学教科书的内容。而在现实生活中,学龄前儿童每天都会参与到科学学习，比如他们会问“怎么样”和“为什么”的问题，然后寻求这些问题的答案。
在他们这个年龄阶段的科学方法不是高科技，而是发现的过程。孩子们是自然发现者，他们会把自己的小脑袋与自然连线从而发现科学。这个世界对他们来说是神秘的，而他们想要了解并找寻答案。
我们可以在家还有学校创造一个培养他们感官能力的环境，让他们来排序分类，触摸、观察、建造和提问。这就是发展他们在物理世界的感官区域的过程。
鼓励探索科学意味着鼓励好奇心。这里有一些很好的活动建议。
假设和测试
我认为蓝色和黄色颜料混合在一起会变成红色；好…让我们试试吧！
什么东西会沉下去或漂浮起来呢？你可以把一堆玩具和家居用品放在浴缸旁边，然后让孩子猜一猜，最后把它们放进水里。
观察
有什么东西对我们来说是依旧奇妙并且对于孩子们来说也是新鲜的呢？可以来一次春天踏青散步，给孩子们指出花朵的花蕾。一起观察它们现在是什么样子，并讨论一下“它们将来会变成什么样子呢？”
分类你的世界
告诉孩子秩序是自然的基础。当你们一起吃饭的时候，把水果和蔬菜分开，并指出奶制品、谷物类和蛋白质。当阅读一本关于动物的书时，讨论五种动物的分类：两栖动物，鸟类，鱼类，哺乳动物和爬行动物。如果你不太记得如何区分，可能你也要温习一下自己的初中科学了！
调查东西
现在大量的儿童读物都有有趣的图片和影像来介绍主题。一起阅读各种小说和传记。例如：饥饿的毛毛虫不但是一篇经典故事，而且阅读这本书可以很好地了解有关毛毛虫生命阶段的科学。
We often think of scientific learning as a chemistry experiment or memorizing biology textbook details. In reality, preschoolers engage daily in scientific learning: they ask “how” and “why” questions and seek answers to these questions.
The scientific method at this age is not about high-tech equipment but about the process of investigation. Kids are natural investigators with young minds that are hard-wired to engage in science. The world i(⊙o⊙)…s a mystery and they want answers!
We can help them at home and school by creating an environment that engages their senses and lets them to sort and classify, touch and observe, build and ask questions. This is the process they use to build their sense of the physical world.
Encouraging science means encouraging curiosity. Here are some things you can do to encourage a scientific mind.
Make hypotheses and test them. I think blue and yellow paint make red when mixed together… Let’s find out! What will sink or float? Put a bunch of toys and household items next to the bathtub, make your guesses, and then toss them in one at a time.
Make observations. What is obvious to us is still wondrous and new to our children. Go on a nature walk in spring and point out the flower buds. What are they now, and what will they become?
Categorize your world. Show children that order underlies nature. When eating, separate your fruits and vegetables and point out dairy, grains and protein. When reading a book about animals, talk about the five categories: amphibians, birds, fish, mammals and reptiles. If you don’t quite remember the differences, you may have to brush up on your own science to stay ahead of Junior!
Investigate stuff. There are a wealth of children’s books that explain any number of topics using fun photos and imagery. Read a variety of fiction and non-fiction together. The Very Hungry Caterpillar is both a classic tale and a great way to learn about the science behind the life stages of a caterpillar.
