Grime Scene Investigation

Grime Scene Investigation is a science based project involving one to two scientific teams from your school investigating the estuary of the Georges River at Sans Souci. The project is based on a scenario where the scientific team/s work as an environmental consultancy team to investigate the waterway and prepare a State of the Environment Report for the fictitious Bay City Council.

The curriculum content is based on Quality Teaching principles and will support student outcomes in Science and Technology and Geography. Students are assigned scientific roles and undertake web-based research in preparation for their fieldwork tasks.

The scientific investigation team has five roles – Ecologist, Biologist, Microbiologist, Water Quality Chemist and Environmental Scientist. On the fieldwork day the students complete all the activities together as a team.

Key syllabus outcomes

  • plans and conducts scientific investigations to answer testable questions and collects and summarises data to communicate conclusions
  • plans and uses materials, tools and equipment to develop solutions for a need or opportunity
  • examines how the environment effects survival and adaptions of living things
  • describes the structural and behavioural features of some Australian native plants and animals and why they are considered to be adaptations

Integrating the Sustainability and Information and Communication Cross Curriculum Priorities is a feature of the program

Skills outcomes

On the day students will :

  • plan and apply the elements of scientific investigations to answer problems
  • manage investigations effectively, individually and in groups

Student pre-visit and follow up activities

Successful excursions have direct links to current classroom learning. Pre-visit activities carried out prior to the excursion will help students better understand their excursion content and provide connectedness and relevance to classroom learning.

For students to familiarise themselves with the fieldwork content visit the Grime Scene Investigation website.

On the day activities

The scientific team/s will be engaged in a series of hands-on activities on the fieldwork day including:

  • undertaking a cruise on the Georges River to observe land uses and associated environmental issues/impacts
  • viewing and identifying types of plankton (collected en route and prepared by teachers) using a microscope projection
  • testing water quality
  • observing and studying adaptations and interrelationships of estuarine species commonly found in estuaries
  • conducting a transect of beach litter and marine debris
