Lesson summary

This lesson incorporates clips from Blue The Film as learning inspiration. Students investigate ocean acidification, and its impacts on marine ecosystems and species. They begin by watching a clip and participating in a guided discussion around ocean acidification. Students then work in groups to conduct experiments designed to simulate ocean acidification and create scientific posters to share their results. They will then look at the difference between ocean acidification and coral bleaching. Finally, students are asked to work as a class to suggest actions we can all take to prevent further ocean acidification and coral bleaching events.

Learning intentions:

Students can...

  • understand some of the ways climate change is changing our oceans through ocean acidification and coral bleaching.

Success criteria:

Students will...

  • be able to conduct an experiment
  • be able to analyse experiment results and communicate results to an audience
  • know what ocean acidification is and how it affects marine ecosystems
  • know what coral bleaching is and how it affects marine ecosystems.

Curriculum Mapping

Australian curriculum content descriptions:

Year 8 Science:

  • Chemical change involves substances reacting to form new substances (ACSSU225).
  • Identify questions and problems that can be investigated scientifically and make predictions based on scientific knowledge (ACSIS139).
  • Collaboratively and individually plan and conduct a range of investigation types, including fieldwork and experiments, ensuring safety and ethical guidelines are followed (ACSIS140).
  • Communicate ideas, findings and evidence based solutions to problems using scientific language, and representations, using digital technologies as appropriate (ACSIS148).

Syllabus outcomes: SC4-16CW, SC4-4WS, SC4-5WS, SC4-6WS, SC4-9WS

General capabilities: Critical and creative thinking

Cross-curriculum priority: Sustainability OI.7, OI.8

Relevant parts of Year 8 Science achievement standards: Students compare physical and chemical changes. Students consider safety and ethics when planning investigations, including designing field or experimental methods. They identify variables to be changed, measured and controlled. They explain how modifications to methods could improve the quality of their data. They use appropriate language and representations to communicate science ideas, methods and findings in a range of text types.

Unit of work: Blue The Film – Science – Year 7 & 8.

Time required: 120 mins +

Level of teacher scaffolding: Medium – oversee experiments, lead students in discussion.

UN Sustainable Development Goals

Goal 14: Conserve and sustainably use the oceans, seas and marine resources for sustainable development

  • Target 14.1: By 2025, prevent and significantly reduce marine pollution of all kinds, in particular from land-based activities, including marine debris and nutrient pollution.

Additional Info

Blue is a feature documentary film charting the drastic decline in the health of our oceans. With more than half of all marine life lost and the expansion of the industrialization of the seas, the film sets out the challenges we are facing and the opportunities for positive change. Blue changes the way we think about our liquid world and inspires the audience to action. Find out how to screen or download the film here. Along with the film is an ambitious global campaign to create advocacy and behaviour change through the #oceanguardian movement.
