There are five methods of seed dispersal. They include gravity, mechanical, animal, water, and air. Scholars study seed dispersal in lesson five of the series of six. Through discussions, hands-on analysis of different seed types, and testing how far their seeds will disperse, groups then consider whether plants' ability to migrate is affected by climate change.

Instructional Ideas

• Depending upon the size of classes, have two fans, two buckets of water, and two stuffed animals so groups aren't waiting their turns

Classroom Considerations

• Duration of the lab could be two to four class periods
• Each group needs at least three different types of seeds that are dispersed in different ways; a link to Carolina Biological Supply is included where you can order sets of seeds

Pros

• Great hands-on activity to understand seed dispersal, which then translates this new knowledge to a real-world event, climate change
• Lab provides all worksheets, directions, links to related resources, and extension suggestions

Cons

• None
