Plant Wonders: The Science of Seed Dispersal
The Hidden Journeys of Seeds
Every towering tree and blooming flower begins with something small and easily overlooked: a seed. What makes seeds remarkable is not only the life they contain but also the ingenious ways plants ensure those seeds reach the right places to grow. Seed dispersal- the process by which seeds move away from their parent plant- is essential for maintaining healthy ecosystems, preventing overcrowding, and giving new plants the best chance to thrive. For students, learning about seed dispersal is a chance to see nature’s problem-solving in action. Seeds reveal how living things adapt creatively to unique challenges.
Nature’s Creative Solutions
Plants have developed an incredible variety of ways to spread their seeds. Maple trees send out ‘helicopter’ seeds that twirl gracefully to the ground, slowing their fall so they can land farther away. Burrs use hooks to hitch a ride on passing animals (or kids’ shoelaces!), while coconuts and other buoyant seeds float across rivers and even oceans. Some plants launch their seeds explosively, while others package them inside delicious fruits that entice animals to carry and scatter them. At the Mar Vista Green Tent on 11/9,, we will give participants the opportunity to model these different seed dispersal techniques and understand them on a deeper level through hands-on engagement. Come by for some science fun!
PS Science
PS Science was launched in 2006 as a project of the Crossroads Community Outreach Foundation, an initiative of Crossroads School in Santa Monica in response to a chronic deficit in public schools- the lack of meaningful early elementary science education. Our programs and curriculum provide elementary students with a foundational understanding of the world around them, using hands-on STEM lessons to promote curiosity and critical thinking.
