STEAM主题陪玩——下雨啦!
这次的陪玩主题是“下雨啦!”。
下雨时,我们都会躲进房子里躲雨。小小建筑师们,你搭建的乐高房子能够防雨吗?下大雨时,如果乐高娃娃们都躲进了你搭好的房子里,他们会被淋湿吗?
一、主题引入
下大雨了,让我们一起给乐高娃娃们搭建一个能够躲雨的家吧!
在开始我们的小实验之前,我们先和孩子讨论一下生活中的房子都是怎样的?不知道怎么提问?问题和图片我们都替你准备好啦!中英双语,外教指导,地道地和孩子对话。
- 生活中的房子都是怎样的?
- What shape can you see in a house?
- 是的,城市里的房子一般是高高的大楼,是一个个长方体,楼顶是平平的。
- Most buildings in the city are tall and in the shape of a cuboid. Their roof is flat.
- 快看图片,其实还有很多很特别的房子哦,比如内蒙古的蒙古包、三角形屋顶的房子、西北黄土高原上居民居住的窑洞、古时候的茅草屋……
- Take a look at the pictures. There are buildings in other shapes too: such as Mongolian yurts, houses with triangle shape roof, cave houses in the Northwest plateau, and thatched houses.
- 观察一下,这些房子都是用什么材料做成的呢?
- From the pictures, can you tell what materials were used to build these houses?
- 你觉得要怎样设计乐高小屋的屋顶,下雨时屋顶才不会漏水呢?
- How can we build a lego house that does not leak when raining?
二、材料准备
We will need:
◎ 乐高 lego
◎ 水 water
◎ 小花洒 watering can
◎ 纸 paper
◎ 锡纸aluminum foil
◎ 布 cloth
◎ 保鲜膜或塑料袋 plastic wrap or plastic bag
◎ 胶带 tape (也可以不用)
三、动手验证
Step 1:“乐高小屋”自由搭建
首先,给孩子自由搭建的时间。让孩子用乐高自由搭建出心目中的乐高小屋!这段时间里,我们给孩子自由发挥的空间。
Step 2:乐高小屋可以防水吗?
孩子搭出的乐高小屋是怎样的?和孩子讨论一下他的作品吧!
- 我们用小花洒往乐高小屋上淋水,模拟“下雨”!看看乐高小屋是不是避雨的好场所。
- Let’s use the water can to create rain and see if the lego house is a good place to stay dry.
- 哎呀,乐高娃娃们躲在乐高小屋里,却被淋湿了!外面下大雨,屋里下小雨,这个乐高小屋的屋顶是漏水的!
- Oh no, the lego characters in the house are wet from the water that leaks through the roof.
- 看来我们需要改进一下我们的小屋子!
- Let’s see how we can water proof our lego house.
Step 3:改进你的乐高小屋
- 看看这些的图片,这些房子的屋顶都是用什么材料做的?
- Let’s take a look at the pictures and see what materials were used to build the roof of the houses?
- 我们来尝试一下给屋顶加一些材料吧,看看加什么材料的效果最好?
- Let’s try and add different layers to our lego house roof. What material should we use?
方案(一):纸屋顶 Paper Roof
在屋顶上盖上一层纸,刚开始的效果还不错,但是过一段时间,纸就破了
Put a layer of paper on top of the lego roof. It works in the beginning to keep the rain out. But after a while, the paper falls apart.
方案(二):锡纸屋顶 Aluminum Foil Roof
加锡纸看起来是个不错的方案!哇!锡纸把雨水都挡住了!这个设计太棒了!
Aluminum foil is a great one. It keeps all the water out. Wow, what a great idea!
方案(三):塑料膜屋顶 Plastic Wrap Roof
保鲜膜(或塑料袋)呢?哇,这个设计也很棒!
How about using the plastic wrap (plastic bag)? Wow, this is also a great idea!
方案(四):布屋顶 Cloth Roof
再试试给我们的屋顶盖上一层布吧!哎呀,虽然能起到一定的防水作用,但布浸湿了后,水就漏下来了!
Let’s try put a layer of cloth on the roof. Oh no, although it keeps the water out for a little bit, the roof starts leaking after the cloth is soaked.
方案(五)、脑洞大开的其他方案
我们还可以试试看其他脑洞大开的方案哦!比如草、树叶、树枝、金属丝等等,只要你想得到的,都可以找来试试看!
在屋顶上加上草(如果没有,就试试树叶、树枝吧),仍然容易漏水,看来我们加的草不够密集呀!
Put a layer of grass (or leaves and tree branches) on the lego roof top. The water still leaks into the house. It looks like we don’t have enough grass.
方案(六)、进一步的改进与测试
你搭的房子是平顶的还是三角形屋顶的?我们分别搭一个平顶和三角形屋顶(分别铺上锡纸),测试一下排水情况吧!
三角形的屋顶不会积水呢!雨水沿着屋顶就流下来了!
The triangle shaped roof doesn’t trap the water from the rain on the roof. The water runs off the roof to the ground.
平顶的屋顶上积了好多水!要怎么办呢?你可以想办法设计一个屋顶排水的装置吗?
The flat roof traps a lot of water. What should we do? Can you design a system to drain the water?
