Drones

     What is that in the sky? Is it a bird? A plane? Superman? Nope. It’s a drone!
     Drones, also known as unmanned aerial vehicles (UAV’s), have been around for a long time, but their technology has improved considerably in the last 20 years, thanks to engineers who have paid very close attention to nature. These engineers began studying birds, bats, dragonflies, and houseflies to learn about their ability to hover, swoop, fly backwards, and dive. Eventually, they were able to create drones that could mimic the behavior of these fascinating flying creatures.
     So, what exactly can drones do? Initially, drones were used strictly as a military tool, but its uses have increased dramatically in the last decade. For instance, drones can be used as a search and rescue tool by going into places that humans are unable to go, such as earthquake sites and tunnels. They are also used to monitor animal habits and behaviors, farmers’ crop conditions, and approaching storms. 
     Drone uses are endless and can be lots of fun, too. There are many drones now available that are made especially for kids!
