      1.3
 Synthesising                                          Brain storming
how technology
                                                    Ideas to solve
can be used to
                                               the problems identified
solve problems
                                                            Sketch the model
                                           wheelbarrow
Demonstrate that device
invented can be used to                     Device to solve
   solve the problem                    the problem identified.           lever
       identified


Pulley – can lift everything   Wheel barrow – can move heavy thing easily
1.4 Analysing That Technology Can Benefit Mankind If Used Wisely




  Advantages of Technology                  Disadvantages of Technology




          •Communication                 Environmental pollution from increase
Enable human to learn more about                 In waste materials
 things happening around the world
           •Transportation               Environmental destruction result from
       Enable human to travel            excessive usage of natural resources
   far away places in shorter time
             •Agriculture                           Social problem
Machines make it easier to plants
       and harvest their crops             Bad effects on health result from
            •Construction                environmental pollution and excessive
   Roads, highways, bridges and                   use of chemicals
building is easier and faster to build
