Engineering Design Process and Raft Competition

The video discusses the engineering design process (EDP) as a method for solving problems and creating inventions. It explains the steps of EDP, using the lightbulb as a case study to illustrate how iteration leads to improvement. The video also describes a practical application of EDP in a raft race project, highlighting teamwork and problem-solving.
