"Science and engineering use smart designs and observations of nature and space to solve problems and explain surprising sights in our world."
Ask the class before watching:
"What are some clever shapes or designs in nature (like webs, shells, or wings) that you think could inspire a tool to help people on Earth or in space?"
An electrode is a part of a machine that helps electricity do work in a reaction.
In a CO2-cleaning machine, the electrode is like a helper tool that lets electricity change the gas into something useful.
Nanowires are super tiny wires that are so small you need a powerful microscope to see them.
Scientists used nanowires to build a spiderweb-like pattern that could keep pathways open for CO2 to move through.
Efficiency means how well something works without wasting time, energy, or materials.
If a device has high efficiency, it can turn more CO2 into helpful products with less waste.
Orbit is the path something takes as it goes around Earth in space.
A satellite stays in orbit by moving so fast that it keeps circling Earth instead of falling down.
Have students answer these questions after watching the episode.
