If you think that science fair projects can only be done in laboratories think again. Some of the most unconventional projects can be possible at locations such as traffic lights. In fact German zoologist Josef Reichholf, even managed to get a complete book out of this. It all began when he saw that crows would deliberately drop nuts at the traffic lights.

His curiosity had him examine the situation closer. That’s when he realized just how ingenious these crows were. The vehicles would pass over the nuts and crack them open. After the lights turned red again, the crows would swoop down and pick up the food. The cars were being used as a nut cracking service.

There have been other instances of the intelligence of crows and their relatives. This group of birds is called the corvids. The Jackdaw is a prime example. If you want the jackdaw to eat, just point a finger in the direction of the food and it will find it. Owners of Jackdaws have long maintained that these intelligent creatures are able to use human behavior to their advantage.

Research carried out by  a biologist Auguste von Bayern, even suggests that corvids may be able to read the message in human eyes  even better than a chimpanzee. So far chimpanzees were considered the best at deciphering what the human being was trying to communicate. However this new science experiment at Oxford University sure changes that view.  Here are a few tips on getting an interesting science fair project on the way.
