Objective is to plan how to restore the 3 utilities (Gas, Water, Electricity) back to the 3 bunkers.
Setup, piece of paper each + pen/pencil.
They will need to draw 6 boxes as shown in the activity2 image part A, they are then told they have to join all 3 utilities to all 3 bunkers with 1 line to each without crossing any other lines or going under the buildings (as it would be unsafe to do so). they will get stuck at a certain point usually line 9 as this cannot be done without crossing a line / building. the answer on how to do this is in activity 2 picture.
