Building Blocks
A study by Lois Leonard of the Design and Making Center in 2005 showed that children who were exposed to an advanced Lego set called Mindstorm at an early age learned improved math skills, better social communication skills and had a better understanding of spacial relations. Building-block projects even have become something of a sport, with many regional competitions taking place annually; one such competition hosted by the First Lego League (FLL) is held all over the world. Simpler block building kits are also available for younger children; be careful that any kit you buy your child is age-appropriate as building block-sets for older children can be a choking hazard to younger ones.
Robotics for Kids
Robotics at first glance appear to be beyond the ken of even the cleverest of children, however there are robotics learning toys that make robotics far more accessible. Lego with their Mindstorm line offers kid-friendly robotics learning. Some sets even go so far as allowing the children to program robot actions via the computer.
Lego isn't the only option for kid-friendly robotics, there are also quality toys like Meccano which is a metal assembly toy based around nuts, bolts and metal strips. Learning with more than one type of robotic toy set builds a wider understanding of general engineering. Youth robotics competitions such as the FIRST robotics competition are popular for children who have mastered the basics of robotic design and moved on to using more industry standard equipment rather than toy kits.
Sim Games for Kids
Much has been said about the negative effects of computer use for kids, however computer use is far from a bad thing when restricted and taught in moderation. The Sim City series of games, along with its many cousins like Pharaoh, Alpha Centauri and other engineering fantasy games build great enthusiasm for the field. These games range in complexity from creating simple building layouts to advanced challenges like fire prevention, water distribution and even sociopolitical interaction. A study conducted by Princeton university in the fall of 2000 stated that children who play computer games display improved cognitive functions, meaning that playing computer games in moderation can be beneficial.
