I thought it'd be cool to show my students how the golden ratio is utilized in architecture, art, design, nature, etc. I highlighted how cosmetic surgeons often use a facial mask with proportions based off the golden ratio for their patients. Basically, I was setting them up to understand that proportions based off the golden ratio appear to be more pleasing to the human eye.
Then the activity: I would partner students up and give each pair a ruler to measure each others' faces, hands, arms, feet, and legs. They then divide the appropriate measurements to arrive at their own respective ratios. For example, they measure the length of a hand (middle finger to palm) and then measure the length of an arm (wrist to elbow). Divide the arm length by the hand length and tada, we have a ratio!
The goal was to get the kids to understand how "weirdly" enough, most of these measured ratios would be close to the golden ratio. As I passed out plastic twelve-inch rulers, one of my female students looked at me extremely worried:
"Mista, I don't know how to use one of these! Do you start from 1 or 0?!"This question shocked me. I quickly discovered my usual quick-witted response mechanism appeared to be vacationing in the Bahamas. So, I took the ignore approach and hoped she was merely pretending to not understand. Ask your partner, dammit.
About a half-hour later, there was a pair of girls who appeared to be done. I approached.
"You guys look done, nice work. What did you learn?" I asked.
"Mista, according to this, my partner's numbers be closer to the golden ratio than mine. This means I'm ugly, don't it? First it's my mom and now it's this worksheet. That's some bullshit!"Uh... Whoops.
