Turtle Travel Tips: How Magnets Can Help Us Navigate | Magnetoreception

Jessi and Squeaks plan a hike to see a waterfall, discussing the importance of a compass to avoid getting lost. They meet Dr. Turtleman, who explains how sea turtles navigate using Earth's magnetic fields, a process called magnetoreception. This ability is shared by other animals like birds and dolphins. The video highlights the science behind magnets and how they help in navigation.
