Investigating technology
1) Technology has been developed and used throughout history to overcome human limitations and problems encountered in daily life. Examples of early technologies include microscopes, telephones, bicycles, and airplanes. 2) As technology advanced, it began to be applied to areas like agriculture, transportation, construction, and communication to make tasks more efficient. For instance, tractors and combine harvesters streamlined farming work. 3) When problems in society are identified, technology can potentially be used to solve them. For example, lever and pulley systems can help lift heavy objects, while wheelbarrows can aid in moving heavy loads. However, overuse of technology may also cause environmental damage and social issues if not implemented wi
