火山爆发
.
..
创新实验目的:
知道热水的密度小于冷水
实验仪器: :
玻璃缸或盆1个,冷热水若干、墨水少量、带盖的小瓶1个.
实验装置图:
实验操作步骤:
1 在玻璃缸中倒入3/4的冷水。

2 把小瓶中装满热水,加入几滴墨水,拧紧瓶盖,并摇晃均匀。

3 把小瓶放在缸底并拧开盖子。

4 观察墨水喷向水面:热的染色水在冷水的上面形成了一层。

5 冷却后观察,染色水就会与冷水混合。

.
实验现象原因:
瓶子里的热水比较轻,. 热水的密度小于冷水,热的染色水在冷水的上面
形成了一层,像火山爆发一样。

实验创新点及意义:
利用身边的小器材,把热水的密度小于冷水演示了出来。

The furthest distance in the world
Is not between life and death
But when I stand in front of you
Yet you don't know that
I love you.
The furthest distance in the world
Is not when I stand in front of you
Yet you can't see my love
But when undoubtedly knowing the love from both Yet cannot be together.
The furthest distance in the world
Is not being apart while being in love
But when I plainly cannot resist the yearning
Yet pretending you have never been in my heart. The furthest distance in the world
Is not struggling against the tides
But using one's indifferent heart
To dig an uncrossable river
For the one who loves you.。
