Product Description: 

 

★ understand the structure of ancient Chinese agricultural implements. 

★ about gear linkage and leverage action can produce high efficiency. 

★ understand the dynamic potential energy conversion and transmission 

 

 

■ develop children's ability to do it yourself， let the children understand how people in ancient times the basic structure of the use of water and water tankers. 

■ hydraulic car experiment mainly crank， water wheels， axles and waterwheel Usuki other components. Water is the water wheel and the flow of energy into potential energy drop of a basic mechanical energy. Hydraulic car is driven by the rotation of the water wheel up and down movement Usuki， in addition to the use of wheels， shafts， but also the use of the principle of the lever， so waterwheel operation work. China was founded on agriculture， arable land due to the need， in order to have a waterwheel irrigation manufacturing. For a long time， water tankers in our rural areas on the prevalence of， and in the era when a lot of manpower replacement.

  ◆ explore kid is exploring， he is not simply learn science， but involves many disciplines， such as physics， chemistry， astronomy， mathematics， and visualization， modeling， standardization. The purpose is to interest from the start， children learn to find points of interest， thereby effectively guide and eventually let the children interested in learning. Scientific thinking to real-world feel wonderful， let the children away from the virtual world of computer games.
