Activity: Ingenious: Making Shipping Greener with Hairy Ships Video Questions
In this activity, students will answer questions while watching the video, Making Shipping Greener with Hairy Ships, from the Ingenious series produced by the American Chemical Society. Each episode investigates a different topic related to how leading-edge chemistry is taking on the world’s most urgent issues to advance everyone’s quality of life and secure our shared future. This episode investigates the “fouling” of boats (when aquatic animals like barnacles and tubeworms attach to hulls), and the impact it has on fuel efficiency. Since fouling is a significant contributor to the carbon footprint, this video highlights how scientists were inspired by unique aquatic plants to develop a stick-on silicone coating for ships that prevents animal hitchhikers from getting a foothold.

Video: Ingenious Video 5: Making Shipping Greener with Hairy Ships
The “fouling” of boats — when aquatic animals like barnacles and tubeworms attach to hulls — has been a nuisance for as long as we’ve been sailing the seas. Fouling messes up a vessel’s streamlined shape, decreasing its speed, maneuverability, and in modern times, its fuel-efficiency. Fouling spikes the carbon footprint of the shipping industry, already greater than that of most countries. For centuries, people used copper coatings to prevent fouling. Modern solutions use toxic chemical paints that pollute the water, kill marine life, and contribute to the degradation of our oceans when they wear off. A new approach is trying to work with nature instead of against it. Taking inspiration from the Salvinia plant, which is covered in tiny hair-like structures that make it basically waterproof, scientists are developing a stick-on silicone coating for ships that prevents animal hitchhikers from getting a foothold.

Catalysts, Molecular Structure | High School
Video: Ingenious Video 1: The Strange Chemistry Behind Why You Get Sick on Planes
The compound ozone, a known respiratory irritant, exists in high concentrations at flight altitudes, making the “fresh air” sucked in by air conditioners at those heights, well, not so fresh. In fact ozone exposure may be responsible for many of the short-term discomforts we associate with air travel. What’s more, ozone can react with other compounds in the air -- even the oils of our skin -- to produce other toxic compounds, like aldehydes and ketones. Some planes have catalytic converters, like the ones in cars, which use transition metals to turn ozone into breathable oxygen. But not every plane has one!
