4. Question 6
Scenario
Your village is about to get cellphone coverage. A cellphone company is planning to build a
tower on a hill next to your school. Once the tower is built, the people in your village will be able
to use cell phones. For example, they will be able to phone the doctor, clinic or chemist when
they get sick. Everyone is very excited and they can’t wait to phone their family members who
live far away! Some people are worried that the tower will look ugly. They think that it will not
look nice next to the school that it won’t fit in with the surroundings.
They would prefer a tower that does not look like a tower.
The cellphone company is looking for ideas for towers they can build. They have asked for your
help. Your task is to design and build a model of a cellphone tower.
 Your model should be more than 30 cm tall.
 It should have a flat platform near the top of the tower. In a real tower, technicians will stand
on this platform when they install or fix the transmitters and receivers at the top of the tower.
The platform on your model should not be larger than a 10 cm by 10 cm square.
 The model should fit in with the surroundings. It must be camouflaged in some way.
 The model should be made from strong materials so that it will be stable.
 It should also be rigid and hold its shape.
 Your model should be reinforced using triangulation.
 You can use any suitable building materials for your structure, such as materials that can be
found around your home. Examples are stiff reeds; thin, straight sticks; or hand-rolled paper
dowels.
