In this series of activities, students collect and observe different types of seeds and hypothesize about how they might be dispersed. They also investigate the design of seeds that use a helicopter method of wind dispersal, which offers an opportunity for a design challenge.
This is Lesson 3: Seed Dispersal, from Unit 3 (How Plants Work) in a series of units on plants, animals, and ecosystems. It includes many NGSS correlations for disciplinary core ideas, crosscutting concepts, and science and engineering practices for the lessons, but not all are addressed explicitly in this lesson. Some are more fully addressed in other lessons or would need to be further developed by the teacher.
