Leonardo Da Vinci exemplified the Renaissance Man. He was an "anatomist, botanist, geometer, physicist, architect, mechanical engineer, hydraulic engineer, civil engineer and even aeronautical engineer. Oh, and he also painted a little. Much of his success was due to his incredible skills of observation and his devotion to collecting and analyzing data. In a time when many scientists tried to "see" what they had been told was true, he found truth in what he actually saw.
In this hands-on science course students will try to sharpen their own observational skills. The class will test some of his inventions and some of his theories. Then each student will chose a subject based on Leonardo's work and independently conduct a series of experiments.
The students study force and drag created by air resistance in order to make predictions about the fall of the parachutes. We go on to look at floating and buoyancy. For the final project, the topics covered vary. Students have looked at people's responses to rectangles drawn using the golden ratio, how blue shading affects the perception of depth, the effect of shape on acoustics, mirror-writing and mirror-reading, as well as more motion-based topics involving trebuchets and crossbows.
The first lab report fills the requirements of the first interim assessment. Students make predictions about how the size and shape of a parachute would affect the speed of its fall. The whole class has to then agree on a method of dropping the parachutes and collecting data. Each student has to analyze the class data and write his/her own report.
The third lab report fulfills the requirements for Interim Assessment 4. Each student develops an individual experiment based on background research about a topic suggested by Leonardo's work. Students are required to perform a descriptive statistical analysis of their data using a standard deviation. Each student has to present his or her work to the class and lead a short discussion of the work.
Three laboratory reports. The experiments all come from a subject suggested by Leonardo's work. The first on a full-class parachute project. The second on a small-group assignment on the development of, science behind, and testing of water shoes. The third laboratory report based on an individual project of the student's choosing.
