Big Brain News Ep. 18: Worms, Moon Shadows, and Space Homes!

Episode 18 (2026-03-06) Today’s Stories 1) A New Tiny Worm in a Super-Salty Lake • Scientists identified a new tiny roundworm (a nematode) living in Utah’s Great Salt Lake. • Learning idea: in very salty water, salt can pull water out of living things—so some organisms need special strategies to stay balanced. • Language and community: the name “Wo’aabi” comes from an Indigenous word meaning “worm,” highlighting collaboration and respectful naming. 2) A Total Lunar Eclipse: The Moon in Earth’s Shadow • A lunar eclipse happens when Earth moves between the Sun and the Moon, blocking sunlight from reaching the Moon. • Learning idea: the Moon reflects sunlight; it doesn’t make its own. • Why reddish: some sunlight bends through Earth’s atmosphere, and reddish light can reach into Earth’s shadow. 3) Keeping the International Space Station Running Longer • The ISS is a research lab and living space in orbit where astronauts do experiments. • Learning idea: planning ahead helps keep long missions steady and safe—like not removing an old bridge until the new bridge is ready. • Connect to STEM: life support systems, water recycling, power, and microgravity research. Parent/Teacher Corner These stories are great for talking about: • How scientists name new discoveries (and why collaboration matters) • How shadows and eclipses work • How long-term planning supports safe science in space Discussion Questions • If you discovered a new animal, what would you name it and why? • What would you want inside a space station to help people live there comfortably? Quick At-Home/ Classroom Ideas (No special supplies) • Eclipse model: use a flashlight (Sun), a ball (Earth), and a smaller ball (Moon) to show the shadow. • Design challenge: draw a “space bedroom” with straps, pockets, and a gentle light for sleep.
