First, think about the practice of reproducing someone else's work. Why do we do that? Next read about Leonardo's Anemometro at http://www.da-vinci-inventions.com/anemometer.aspx. Watch the video of his anemometer at https://www.youtube.com/watch?v=Pxp2Q09pVDQ. Then find the story on Get Epic, at https://www.getepic.com/app/read/5693, or on pages 92-95 in Maxine Anderson's "Amazing Leonardo da Vinci Inventions You Can Build Yourself." After reading about both anemometers, follow the instructions to build a hemispherical cup anemometer using the supplies provided. Open a VIDEO app, show your anemometer, and record a reflection to answer these questions: 1) Will your anemometer be an effective way to measure wind? Why or why not? 2) Whose anemometer was better, Leonardo's design or John Thomas Romney Robinson's design? Explain. 3) Why do you think we built the second anemometer design today? 4) Why do you think scientists often reproduce the work of others?
