We are very excited to be back in the classroom this school year! Right now, 8th graders around Las Cruces are learning about magnets, magnetic fields, and how animals use them to navigate. 🧲🧭🐦
In this lesson, students visit two stations to explore how birds may use Earth’s magnetic field to navigate.
At one station, students act as Black chinned hummingbirds migrating towards Mexico in the fall. These tiny birds have crystals of magnetite in their beaks and scientists think that these structures may help them detect Earth’s magnetic field. Students used large magnets to explore magnetic forces and ‘feel’ their way to Puerto Vallarta.
At the second station, students act as Sandhill Cranes migrating from Canada to Mexico. These birds have special proteins, called cryptochromes, in the retinas of their eye. These cryptochromes are sensitive to light, and scientist think they may alter what a bird sees in response to magnetic fields. At this station students use bird vision masks to ‘see’ the way.
More learning, more questions, and more science fun ahead!
