In DT this week, the Butterflies worked like engineers to use equipment safely and effectively. They used skilful hands, excellent communication and problem solving to choose equipment and materials to make working winding gear. We were very impressed with the results and thought about how this design progressed throughout the industrial revolution. We learned that first, women could operate the crank, then ponies took over to take heavier loads. As technology developed, steam engines drove the winding gear, before finally, the dawn of electric power brought on mass production.
