Through a partnership with the Smithsonian National Museum of Natural History, the Fairfax Network is able to offer the Smithsonian Science How webcasts to middle school students. Each webcast provides students with positive STEM role models, information about science careers and pathways, and connections to current research. Students see how scientists and other experts use tools and technology in their work.
How Volcanic Eruptions Send Materials Up and Out with Geologist Ben Andrews — November 14, 2018
What causes ash and other materials during violent "pyroclastic" eruptions to spew out the way they do? Join Geologist Ben Andrews as he explores the physics of explosive eruptions. See how he uses a simulator to model how erupted materials travel. Get Teaching Resources
A Century of Discovery of Sea Urchins and Relatives with Zoologist Dave Pawson — December 12, 2018
How can you study animals that live on the seafloor? Meet Zoologist Dave Pawson, who studies echinoderms in the deep sea, including sea urchins, sea stars, and sea cucumbers. Learn about these creatures and how deep ocean research techniques have changed over the years. Get Teaching Resources
Butterfly Adaptations: How They Come by Their Colors — January 9, 2019
Why is there so much diversity in colors and patterns on butterfly wings? What’s the function? Join Butterfly Pavilion Manager Eric Wenzel and Microscopy Educator Juan Pablo Hurtado Padilla to explore color patterns and the detailed wing structures that give butterflies their colors.

Ferns: Curious Life Cycles and Remarkable Biodiversity with Botanist Eric Schuettpelz — February 13, 2019
Why do ferns look the way they do? How do they reproduce without seeds? Botanist Eric Schuettpelz reveals the unique life cycles of ferns and highlights some of their adaptations. Get Teaching Resources
Fossil Forensics: Plant and Insect Relationships with Paleobiologist Conrad Labandeira — March 13, 2019
Go behind the scenes and meet Paleobiologist Conrad Labandeira, who studies the associations between insects and plants. Did you know that the relationships that sustain our life today — such as herbivory and pollination — have been going on for tens of millions of years? Take a journey chasing fossils back to the time when insect and plant relationships first evolved. Get Teaching Resources
