This 23 second video about an impatient seed pod exploding is a natural phenomena that may be used as a lead into a discussions about another way that seeds disperse.
2-LS2-2 Develop a simple model that mimics the function of an animal in dispersing seeds or pollinating plants. Clarification Statement: none Assessment Boundary: none
This resource was not designed to build towards this performance expectation, but can be used to build towards it using the suggestions provided below.
Comments about Including the Performance Expectation This video clip is to be used as seed dispersal phenomena and to generate student questions and conversations. Students will use the information gained in the video to begin asking questions about seed dispersal. Investigating these questions will lead to developing simple models that mimic the function of an animal in dispersing seeds or pollinating plants.
This resource appears to be designed to build towards this science and engineering practice, though the resource developer has not explicitly stated so.
Comments about Including the Science and Engineering Practice The phenomenon of an exploding seed pod will naturally generate student questions and curiosity. The instructor allows time for student questions and discussion between peers about what is happening to the plant. Sample Student Questions: What happened to the plant? What part of the plant is being touched? What caused the seed pod to explode? Why does the plant need the pod to explode?

Comments about Including the Disciplinary Core Idea Through this seed dispersal video, the educator can extend student learning of how different plants in an area disperse seeds and can further strengthen the concept of biodiversity as not all plants reproduce in this manner.
Comments about Including the Disciplinary Core Idea This is an extension of animal involvement in seed dispersal with a discussion of animals touching or moving past seed pods causing the pod to burst.
This resource was not designed to build towards this crosscutting concept, but can be used to build towards it using the suggestions provided below.
Comments about Including the Crosscutting Concept With further discussion, students learn what caused the seeds to be dispersed.
Comments about Including the Crosscutting Concept No cross-cutting concept is listed for this performance expectation, but discussion of the structure of the seed or seed pod helps students understand how seeds are dispersed so new plants can grow.
