How do we read a thermometer? Simple. According to
http://www.reachoutmichigan.org/funexperiments/agesubject/lessons/caps/thermometer.html it says that your eyes should be level with the top of the liquid in the tube to read it accurately. The reading is not the same when you look down or up onto the degree lines on the tube.
The formulas that help you find the mean temperatures of daily, monthly and annually can be found in our geography textbook. One question: How do they come up with these calculations? Is it because of some pattern the inventor of these formulas saw?
Wind rose was tested in the common test, but some of us weren't familiar with it and thus we wrote down wild guesses. I thought it was meant to tell people how strong the wind is due to the numbers on it. Little did I know or expect it was, according to a friend, the dates. Question: Who invented this and why? Was it because of some incident or because of curiosity? How is it different from the wind vane?
Can you answer them? :)
