Natural Sciences

New semester, New classes, I am on a new journey with a new lesson. This semester, we are learning about natural science, such as what types of elements will affect the environment around you? What is the soil type of this area, and is this place good to build an Ecohouse? Me and my friends is in a group to do this topic's presentation, our location is the Central Mountain Range, and we found some interesting results there, so there is a very special place for anyone to live, so the amount of rainfall is 2-5 times more then city. And the soil is acidic, but there is still an ecosystem that has been in the  Central Mountain Range for over a thousand years. But at all, the result for the Central Mountain Range to build an eco house is not because the acidic soil, 2-5 times more rainfall than the city, and low oxygen.

After the chemical relationship study, we started learning about the energy system. There is an interesting project we did here: making a windmill and pulling a cup up at the same time. So the design wilkl be look like this : 

Here is the design that we made for our windmill. The reason we are pulling the cup is that the cup represents the weight, and the cup will be a test of whether our windmill is stable or not. After each attempt, the teacher will add some weight, like 5 oz, 10 oz, or something else. We will not be making the fan spin with our hands; there will be an electric fan. We will start with the smallest level and then keep increasing until the windmill is strong enough to lift the cup. This work and experience have shown me that generating energy is not just about something running slowly; it is about something that runs fast and is strong enough to stay grounded, regardless of natural or human-made hazards. Stability is the most important factor for a power-generating machine. Then we came up with a small issue, how can we make the fan run normally with no sticking, so me make the stick in the middle of the machine strong, stable, and thin, and we did some research about how does other windmills in the real world look like, then we made the slices of the fan into a small angle, so the wind will cann let our hand made windmill run and holds the weigh.

After this handmade windmill activity, our teacher brought us out of the classroom to do a lab. This lab is about recording the amount of energy that a solar panel can produce when we make the
