We continued our investigation into crafting the perfect paper plane. We talked about wing span, weight, size, and weight distribution. Adding things like paper clips to the tips brought certain results, and different paper weights also yielded different results. Construction paper, it was noted by Richard, is just too heavy for our purposes. We designed, crafted, and tested at least 4 planes. His fine motor workout was also great in terms of the folding and creasing, which is already improving.
