每座大坝产电的能力都不相同,因为产生电的水流的力量有大有小。那么,是谁在影响水流?我们通过实验来看看。你需要:3个塑料牛奶桶或水桶(完全相同),水,钉子,尺子,马克笔,遮蔽胶带,剪刀.记事本,铅笔。第一步:用钉子在第一个牛奶桶底部上方2cm处钻一个洞。第二步:用一条胶带盖住洞眼。第三步:把你的牛奶桶放到水槽里。往桶里装水至高15cm的地方。
The capacity of each dam to generate electricity is different because of the power of the electricity that produces it. So, who is affecting the flow of water? We see through experiments. You need: 3 plastic milk buckets or buckets (exactly the same), water, nails, rulers, marker pens, masking tape, scissors, notepad, pencil. Step 1: Use a nail to drill a hole 2 cm above the bottom of the first milk bucket. Step Two: Cover the hole with a piece of tape. The third step: put your milk bucket into the sink. Place the water in the bucket to a height of 15 cm.
