Smithsonian Science How Webcast

A Century of Discovery of Sea Urchins and Relatives

In this video, zoologist Dave Pawson shares how he studies echinoderms in the deep sea, and how deep ocean research techniques have changed over the years.

Description: 

Meet Dr. Dave Pawson, zoologist at the National Museum of Natural History. He studies echinoderms, which include animals like sea urchins, sea stars, and sea cucumbers, in the deep sea. How can you study animals that live on the seafloor? Take a journey back in time with Dave to learn about the first echinoderms that were collected for the Smithsonian over 100 years ago by Austin Clark, aboard the research vessel Albatross. Marvel at how deep ocean research techniques have changed over the years, as new technology comes into play. See how early research tools and findings laid the foundation for the work that biologists continue today. This show aired Nov. 9, 2017.

Life Science

MS-LS2

Ecosystems: Interactions, Energy, and Dynamics
  • MS-LS2-1Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.
  • MS-LS2-2Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems.
  • MS-LS2-3Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
  • MS-LS2-4Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.

MS-ESS3

Earth and Human Activity
  • MS-ESS3-4Construct an argument supported by evidence for how increases in human population and per-capita consumption of natural resources impact Earth's systems.
