Wacky Properties of Water

Water, water, water!! I've never thought that the properties of water are so wacky. They are so amazing. Some of them really surprised me because I've never known it before. As biology class always leads us to a world of discoveries, I have found out a lot about water properties in this lesson.

The first thing we did today was to review the test we took last week. I was pretty satisfied with my score. The question that I got wrong was an analogy problem. Mr. Olson taught us how to solve these types of problems. I now know what these problems mean and could solve them by making a sentence using the two words given.

Later, we learned stuff about chemistry of cells. I know that besides water, I am also made of carbohydrates, lipids, proteins and nucleic acids. haha... I am made of so many things! In order to let us understand the four classes of organic compounds, Mr. Olson used the powerpoint while explaining.

As sitting on the chair was quite a boring thing, we were told to go to the lab stations to do simple experiments of water after the powerpoint. First, we had to place a drop of water at one end of the wax paper and tried to see how long it would take to get the whole water droplet to the other side. I only used four seconds to do so. That was pretty fast. Then, we had to repeat this thing by using glass slide instead of wax paper. And the result was really contrasting because the water on the glass slide could not be dragged on the glass slide. We finally concluded that water was both cohesive and adhesive. The glass slide is hydrophilic and the paper is hydrophobic. After that, we also did two more experiments. We found out something about capillary action from one of the experiments.

All these experiments are really intriguing. Through them, I can understand better about the WACKY properties of water.
