Parachute Design and Testing Concepts

The video showcases a series of STEM teacher training workshops focused on parachute design. It begins with an analysis of seed dispersal, drawing inspiration from Leonardo Da Vinci's early parachute designs. Teachers are guided through the process of designing, constructing, and testing parachutes using various materials. The video emphasizes experimentation, adjustments, and observations to optimize parachute performance.

What is the initial step in the parachute investigation process?
