Blue crabs are a tasty treat for humans and sea turtles alike. Like many other commercially fished species, blue crabs are often found in and around coastal salt marshes, where they find shelter and meals of their own. But what makes these marshes so healthy, especially when marsh habitat is being lost around the world? Dr. Randall Hughes examines whether having a greater diversity of genetically distinct plants (genotypes) makes for a healthier marsh (and by extension, better fishing). Students will see how salt marshes play a large role in keeping coastal fisheries healthy and how diversity may allow for a stronger ecosystem.

Hank gets into the dirty details about vascular plant reproduction. Vascular plants use the basic alternation of generations developed by nonvascular plants 470 million years ago, but they've tricked it out so that it works a whole lot differently compared to the way it did back in the Ordovician swamps where it got its start. Here's how the vascular plants (ferns, gymnosperms, and angiosperms) do it.

The growth and development of a plant is one of the most spectacular events in nature. Yet, because it happens so slowly, over the course of days or weeks, it is difficult to observe in real time. This video segment depicts plant growth in time-lapse format, allowing the viewer to observe in just a few seconds some of the most important life stages of a plant, from germination to the formation of a flower, and several phases in between. Footage from NOVA: "The Shape of Things."

Mission: Seed Spot | PLUM LANDING

Explore how plants spread their seeds to give their offspring the space and resources to grow in this media gallery from PLUM LANDING. This media gallery pairs a PLUM LANDING animation and a related hands-on activity to provide about one hour of programming. Start by having kids watch Plant Your Socks!, a short animated video about wearing fuzzy socks outdoors to collect seeds on the ground. Then, head outdoors for Seed Travels, a hands-on activity in which kids go on a scavenger hunt to find different kinds of plants and seeds. If time permits, wrap up your day by completing one or more of the “Explore Some More” activities or play the Seed Racer game to explore different ways seeds are dispersed.
