The problem with seagulls!

School Overview

Port Dalrymple School is located in George Town, a large town in north-east Tasmania, on the eastern bank of the mouth of the Tamar River. Port Dalrymple School caters for children from Kindergarten to Year10 from the town and surrounding areas. The school currently has 485 students.

Problem / Challenge

Seagulls are everywhere in the school. They rummage through our bins and spread rubbish around. They are annoying us by snagging our food at break times. They poop and mess up our school. What can we do to stop this?

Brief

In teams of four, device and build a prototype of your own unique solution to this problem.

You might like to consider:

  • special rubbish bins with deterrents
  • deterrent devices producing sound or light
  • decoys
