MIND MAP pages 10-18

1. 1.Man´s progress through technology

   • It has been a constant struggle for the survival of our species.The nature has given us two very important weapons to survival:
     • Intelligent brain capable of solving problems
     • Hands with prehensile fingers, capable of handling tools
       • Having mastered tools, we built machines and new more complex tools
   • The electricity led to the knowledge of electronics and computers.
     • (these are technologycal advancements)

2. 2. Implications and consequences of technical activity

   • On many ocasions human activity has had unexpected consequences, particularly technological activity
     • We have been damaged by enviromental accidents and pollution
     • Example:
       • The extration and subsequent treatment of metals to turn them into technological objets

3. 3. The process of solving technological problems

   • The project method
     • There are no perfect solutions. We adapt the problem to the conditions we are given. Out of possible solutions, we choose the optimal
     • Is a process where we solve problemsby following these steps:
       • Defining the problem
         • Looking for several practical solutions
           • Choosing an optimal solution
             • Planning how to implement the solution
               • Putting the planned solution into practise
                 • Cheking to see if the solution works correctly
                   • Correcting possible mistakes and defects
