When we did the water lab we tried to send water from one container to another by using a string. We also tried to cut the water with a toothpick and it didn't work. The quiz we took told me a lot more about water properties. The one thing I really knew is that water contracts when it gets smaller. An ice cube is a good example of that because you pour it into containers and the it freezes and contracts to stick together and get smaller.
I read an article about water and it gave me a lot of new information. It said that liquid water is the medium of life, that most organisms are over 80% water. Oxygen is when two hydrogen atoms are attracted, but when the temperature is 25 degrees celsius there is only one hydrogen atom. I didn't know what pH was and the article gave me the definition of that. It is the negative logarithm of the hydrogen ion concentration. So the pH scale is an easy way of telling the hydrogen ion concentration.

I think that that experiment sounds like a lot of fun to do. You did a wonderful job on stating facts and things you did not know. I didn't know that when the temperature is 25 degrees celsius there is only one hydrogen atom, that is very interesting.
ReplyDeleteYou made some good points here, such as living things are 80% water. I agree with them because as with other living beings, without water in our bodies, we could not function as we do.
