我们通过实验来探究一下吧!
https://p3-sign.toutiaoimg.com/tos-cn-i-qvj2lq49k0/d6c42e8f1fdf4b9a8cf59efa8fcad986~noop.image?_iz=58558&from=article.pc_detail&x-expires=1668741013&x-signature=WVbcnamOuYj5kEXIxJtUjU0AWwM%3D
“ 会变色的叶子 ” 小实验
【准备材料】:3片不同颜色的树叶,一次性杯子,酒精、白棉纸、剪刀
【实验玩法】:
1、把叶子洗干净并剪碎,按照颜色放进3个一次性杯子中
2、在杯子里倒入酒精,酒精量要没过叶片
3、将白棉纸放进3个杯中,直接碰触到酒精和树叶
4、让孩子仔细观察白棉纸颜色的变化
【实验原理】:叶子中存在的叶绿素、叶黄素和花青素能够溶于酒精,因为不同颜色在液体中的运动速度不同,所以颜色会在白棉纸上分离开来。

乘风破浪的树叶

船可以用什么驱动呢?
睿睿:风、油、还有电。
老师告诉你们:洗洁精也可以驱动小船哦。
今天我们就来玩一个好玩的科学小实验“乘风破浪的树叶”。
在叶子上滴洗洁精,就可以驱动叶子前进啦!
https://p3-sign.toutiaoimg.com/tos-cn-i-qvj2lq49k0/3d98fa48132443f1ac49af05fdcb1ec1~noop.image?_iz=58558&from=article.pc_detail&x-expires=1668741013&x-signature=nBN9irEFMDPObPyPqb7YeGRYv2I%3D
【实验材料】:水、洗洁精、叶子、盆子
【科学原理】:液体表面有表面张力,在遇到洗洁精也就是表面活性剂后,张力就会被破坏。树叶尾部就会失去张力,但叶子前方的张力并没有遭受破坏,受前方张力的影响,叶子就会向前行驶,这就是我们运动的原理。

和煦的阳光,透过稠密的树叶洒落下来形成了金色的光斑。通过本次科学探索活动,小朋友们对树叶有了很多的了解,也更加热爱大自然了!这也许就是大自然的魅力吧,总在无形中吸引孩子们目光。关于“一片叶子的旅行”科学探索课程故事我们就和大家说到这里啦~
