星期六的时候，我和妈妈还有一位妈妈的同事，和她的儿子，只要我们俩写完了作业，就带我们去实验室做化学实验。那位阿姨的儿子比我小几个月，是我的弟弟。
好不容易把作业写完了，就剩下一篇博文了，妈妈也正好下了课，我和那个弟弟就如愿以偿的去了实验室做化学实验。
刚到那儿，妈妈就给我们变了一个“魔术”：她拿起了一瓶装有透明液体的玻璃瓶，往试管里倒了一点，然后又拿起了另一瓶还是装着像水一样的玻璃瓶，又往试管里倒了一点，然后轻轻地摇了摇，突然，试管中原来像矿泉水一样的液体，竟然变成了桃红色的液体。
这是为什么呢？原来，妈妈第一次倒进去的是碱，第二次倒进去的是酚酞，酚酞原本是没有颜色的，可是，在碱的作用下，酚酞的颜色就变成了桃红色。原来是这样，化学实验真是太有趣了！
那天，我们还做了很多有趣的实验，化学真是奇妙啊！

以后，将会有一座未来的智能化学校，那里面有很多的电子设备，而且都看不见。
未来的智能化学校的师生都可以在饭堂里用餐，这样，就不需要清洁阿姨每天帮我们抬饭桶了。饭堂里还有一些会动的管子，只要把各种各样的调料放在管子上，让管子开始转动，如果你需要什么调料，就可以在餐桌上的电动表上点一下你需要的调料，这时，管子旁边的机器手就会把调料放在罐子里并运到餐桌旁。
教室也很先进，可以调温度和湿度，也可以开空调，而且椅子可以调高度。老师们使用黑板将会很方便，两旁有一个机器手，如果老师把黑板写满了，只要按一下按钮，机器手就会立刻把黑板擦干净，让老师继续使用。
在操场上，还有一个地震仪，如果地震仪发出耀眼的闪光和悦耳的叫声，就说明五天后将会地震。
这就是未来的智能化学校，它给我们带来了方便。
