We brought Unit 1 to a close by revisiting the Golden Ratio. Students were introduced to the concept of “respectful scientific discourse” and practiced sharing their thoughts about whether the Golden Ratio should be considered science or pseudoscience. Students practiced discourse in groups of 4 multiple times throughout the period. Between group discussions, we revisited the Golden Ratio. Students re-watched a segment of the first video (below) and we discussed the effect of the video production (music, narration, images) on their perception of the Golden Ratio as science or pseudoscience. Students were reminded of the Bill Nye video we watched where they learned that practitioners of pseudoscience often play on our senses and our emotions to try and earn our trust (and our money!). We then watched a video by Hank Green (SciShow), where the Golden Ratio is presented in a style that might be seen as more credible than the first video. We concluded the lesson either by watching video segments by Vi Hart (see the September 21 post), or more comprehensibly for the students, through an artistic representation by the teacher, of how the Golden Ratio manifests in plant growth through the actions of hormones. As our understanding of plant hormones and genetics grows, it would appear the Golden Ratio is in fact firmly grounded in science, as least with respect to plants.
