把水池的排水口堵死,然后打开水龙头,让它慢慢滴水。一个小时后关闭水龙头,用量杯测量水池里的水。如果水龙头像这样滴了一整天(24小时),那么会有多少水被浪费掉呢?如果滴了一周呢?一年呢?计算一下。如果一个水龙头以每秒一滴的速度滴水,那么一年就将浪费9600升水。如果这些水还是热的,那么同时也浪费掉了能量!这是我们做的实验,实验做完后可不要把水池里的水白白放掉哟!把水盛到水桶里,用来擦地、流花、冲厕所……用你能想到的一切办法来利用它吧! Block the drain in the pool, then turn on the tap and allow it to drip slowly. Turn off the faucet an hour later and measure the water in the basin with a measuring cup. If the faucet drops all day (24 hours) like this, how much water is wasted? If it drops for a week? A year? Calculate. If a faucet drops at a rate of one drop per second, a total of 9,600 liters of water will be wasted a year. If the water is still hot, then at the same time also wasted energy! This is our experiment, after the experiment is done not to put the water in the pool free! Put the water in the bucket, to rub the ground, Liuhua, flushing toilets ... use whatever you can think of ways to use it!
