1. The application of scientific knowledge for practical purposes, especially in industry.
2. Machinery and devices developed from scientific knowledge.
3. The branch of knowledge dealing with engineering or applied sciences. (Oxford Dictionary)
Educators recognise that a balance is needed between digital learning and practical experience, and hands-on experimentation often leads to complicated engineering and "machinery developed from scientific knowledge”. Equipment that is durable, modular and fosters curiosity and imagination supports STEAM (Science, Technology, Engineering, the Arts and Maths). If this is so, block play is at the foundation of technology.
Take a look at this steam engine built out of Unit blocks by two five year old boys. It makes you wonder what they will be building in 20 years!
