The spider sprinkler irrigation system at the school is not working properly because early years students have been unscrewing the heads of the spider drippers, causing flooding. The proposed solution is for the teacher Nicola to take each class to the area with the spider drippers and explain to the students that they need to leave the sprinkler heads alone or they will have to sit out of break time. An alternative backup plan is to make bottle sprinklers as a more sustainable and difficult to break option for watering the plants.
