This is an activity a group of teachers I was working with fleshed out based on ideas on Mark Wahl’s website, and here. This activity is appropriate for Math 10-3 (Measurement) and Math 10C (Measurement or Real Numbers).
Statues of human bodies that the ancient Greeks considered most “perfect” embodied many Golden Ratios. It turns out that the “perfect” human face also contains many Golden Ratios. This task allows students to take measurements of an ancient statue, and check whether these measurements approach the Golden Ratio. Then two celebrity photos are provided and the students check how beautiful the celebrities are based on these calculations. Finally, students can use pictures of their own faces and GeoGebra to check how they match the Golden Ratio.
Part 1 Students perform the measurements on a photo of a statue, and calculate the ratios requested. These measurements could be made by printing the picture and physically measuring, or by inserting the picture into GeoGebra and using the software to measure.
Part 2 Students complete the same measurements, either on a provided celebrity photo, or one of their own choice.
Part 3 Students then take their own picture and insert it into GeoGebra. They can then measure, and check how closely the ratios in their own faces match the Golden Ratio. Students who are not comfortable using their own pictures can choose other celebrities from the internet. (I didn’t teach Cameron Diaz, but her face is much more likely to be beautiful using this test than my own…)
The complete student package in Word format is available for download here.
How can I use this to give a rating out of 10 for attractiveness?
The internet is fueling the success of music because
it can be listened to at any time of the day and anywhere in
the world. And once you have your own project that you want to promote, you
must have considered the radio as one of the best alternatives to introduce your
music to the crowds. But mostly BBC Radios 4 and 5 because, being speech orientated, they’re more like what I do, so I can learn lots from them.
