Study after study indicates that children learn best with movement. If this is the case, why are children still required to sit for numerous hours at a desk during school? Teachers still continue to take recess away from children that misbehave, but isn't it clear that they misbehave because they need the movement? I don't think this is rocket science! Check out this awesome Natural Energy Park that You Song Young, Jin Soo Yeon, Ahn Ho Sang, and Lee Sung Jae from Hyundai Engineering and Construction designed. I doubt there would be any behavior issues if every school had one of these! Children can have the time of their lives, but also learn tons! They can see how movement, the sun, magnets, and water create energy. They can spin a wheel to make a kite light up. They can experience how kinetic energy is converted to light and sound by pedaling a bike. The children can control a small plane with a lever that uses power from a magnet. These are just a few of the amazing things children can experience! Hmmm... 2 hours on the playground learning these concepts or two months sitting at a desk reading a text book???
