Follow Your Nose

The beaks of some birds contain a small spot of a magnetised rock called magnetite. This may act as a tiny GPS unit, providing information about the position of the Earth's magnetic poles. We also have small amounts of magnetite in the bones of our noses. Do you think we use the earth's magnetic field to know which way we are headed? How could you test this theory?

Pacific Parasite

The koekoeā, or long tailed cuckoo, is an extraordinary bird. Not only does it travel vast distances across the Pacific, it's also a fearsome hunter and a pesky parasite. It lays eggs in other bird's nests and leaves them to raise the babies. Investigate the life cycle of the koekoeā, and present the results either verbally (as a speech or a video), visually (on a poster or pamphlet), or electronically (Powerpoint or Google doc).
