You may be familiar with GPS, which stands for for Global Positioning System.
GPS uses satellites to zoom in on users’ locations and tell them how to get where they want to go. Without GPS, many would have a hard time finding their way around. Animals don’t have GPS, yet they rarely get lost. Sometimes, animals travel long distances without losing their way. Their “secret,” some scientists say, is a magnetic sixth sense. Some plants have it, too.
