This worksheet is a bit intellectually difficult, as students learn about 3 different processes: Scientific Method, Engineering Design and the Biomimicry Design Spiral. It helps them to see the differences and similarities and how each can be used. I give this to my honors Biology class and they understand it since I have lectured on these processes before. It is helpful in introducing the Engineering component of NGSS. If you want even more challenge, have them make a venn diagram of the 3!
