In this STEM lesson, students will: 1) Learn about and research many seed dispersal methods used in nature (gravity, water, wind, animals, etc.), watch videos, explore pictures and diagrams, and take notes on what they learned. 2) Use a template to create a paper helicopter seed and then design a new one to either drop slower than the original or drop faster than the original by changing a variable of their choice. 3) Conduct a fair testing procedure to compare their new prototype designs to the
