I asked several of my classmates what they thought of my presentation, and overall, they all pretty much said the same thing: the information was good and clear but you could see that I was nervous. Kalli also said that she liked my mini anemometer as it helped her visualize what a hemispherical cup anemometer looked like. However, Khaliun said that I had good information but I sort of stammered. I talked about the different kinds of anemometer, why I chose to research on anemometers and what were the positive and negative points of researching about it. If I was to do my presentation again, I would practice more at home. It surprised me because I am normally confident of talking in public, but I was sort of nervous during this presentation. If I had practiced more, it would have helped, I briefly practiced once, but I could have practiced more than that. However, I like my information and my model. Even if I stammered a lot, I think I was sort of clear. I also talked about what was easy to find and what was hard, and why I chose the anemometer, and I think that really helped my grade.

- Detailed
- Hemispherical cup anemometer
- In colour
- Labeled
- At least A4 paper size
- My first sketch was detailed, was a hemispherical cup anemometer and was on a A# paper.
- My second sketch was sort of detailed, was a hemispherical cup anemometer, in colour, labeled and on a A4 paper.
- My third sketch was sort of detailed, was a hemispherical cup anemometer, in colour and on a A4 paper.
The sketch that met the most specifications is my second sketch. It is in colour, it is labeled with the most parts i could find, it was a hemispherical cup and on a A4 paper. That is why i chose my second sketch.
I could have made it better, by researching even more on the different parts of an anemometer, because right now it just has three labels... Also, i could have put on a A3 paper.

The Anemometer is an instrument that is used to measure windspeed. They are two types of anemometer: The mechanical anemometer and the hemispherical cup anemometer (that is the most common one used).
The mechanical anemometer is made with a perpendicular disk to the wind. It was invented by the Italian art architect named Leon Battista Alberti, in 1945. The windspeed could be told by looking at the inclination of the disk in the wind. The mechanical anemometer was later reinvented by the Englishman Robert Hooke, who is usually mistaken for the first inventor, in the same time that Mayans built windtowers (basically anemometers). Wolfius also re-invented the anemometer in 1709.The Hemispherical Cup Anemometer
The hemispherical cup anemometer is consisted of of four hemispherical cups that rotate with the wind. A arrangement of wheels say how many times did the cups rotate a full revolution in a specific amount of time. the hemispherical cup anemometer is still used today. It was invented in 1846 by John Thomas Romney Robinson, an Irish researcher.
