The new series of educational models of the Academy brand is intended for children over 8 years old and adolescents. It allows you to familiarize yourself and approach certain inventions made by man throughout history, while having a playful appearance by mounting the models. The realization requires neither glue nor tool, the different parts fitting into each other. The assembly explained by diagrams is very easy, just respect the numbered steps.\nThe models are functional, either thanks to solar energy (a mini solar panel is in this case provided), or thanks to wind energy (propeller provided), or thanks to a battery (not supplied). They are even ideal bases for an initiation to engineering sciences and educational fun allowing the knowledge and understanding of systems present in our environment.\n
