Water Description

Exploration Name: Liger Water System

Exploration Dates: August 12 – September 26

Number of Students: 12

Description: In our water group we learned about the pH of water. The full words of pH is Percent Hydrogen. That is the kind of scale that people use to measure the acids and bases. The scale of pH is 0-14. From 0-7 is acidic, 7-14 is basic and 7 is neutral. The hydrogen (H+) is acid and hydroxide (OH-) is base. When we learned about pH we did the experiment with 13 liquid things. For ex: the coca-cola and pond water. The coca-cola was 2.0 so it means acidic. If we drink it a lot like every day we would get sick but if we drink in 1 week only 1 it will be good. The pond was 10.0 so it means basic and if it has a lot of basic like this it also not good for our health either. So we can eat or drink only higher than 7 to 9 or lower than 7 to 5, so it not really have many bases or acids. In this class we also studied about algae. Algae is the kind of plants that live in water and it uses the sun as it food. When this plant lives in water it will make water become basic. We studied our own pond at Liger to learn about this. One other thing that we learned was the water cycle. We learned when the sun rises then it does the evaporation with water. When water goes up it is not yet become the clouds but when the temperature is cool then it makes condensation so it becomes the cloud. When the cloud in the sky catches the cool temperature it will become the rain again. To learn about water we went on the trip to RDI. RDI is the place that makes the water filters to sell. One thing that we learned from there is why they made this RDI place because they saw that some people here don’t have the clean water to drink so they can buy it to get the filter and clean for them. Another reason is when they sell the water filter they sell as cheaply as they can to help the people in Cambodia.
