    • Engage students in a discussion about their findings, encouraging them to think critically about the similarities and differences between these two ecosystems.

7. Hidden Value of Kelp

  • Activity: Exploring Ecosystem Services

    • Introduce the concept of ecosystem services and their categories: provisioning, regulating, cultural, and habitat services.

    • Guide students to watch the video on ecosystem services using the QR code or link, and then have them list the benefits that kelp forests provide to their community.

    • Instruct students to categorise these benefits into the appropriate ecosystem service category. For advanced learners, encourage further exploration by comparing these services with those of other marine ecosystems, such as coral reefs.

8. Giant Kelp Threats

  • Activity: Understanding the Decline of Kelp Forests

    • Discuss the significant threats facing giant kelp forests, including climate change, lack of nutrients, and tropicalisation.

    • Have students match definitions to terms related to these threats and then describe in their own words how each factor impacts kelp forests.

    • Use this opportunity to clarify any misconceptions and ensure students understand the broader implications of these environmental changes.

9. Restoration

    • Introduce the concept of kelp restoration, using the example from Reviving Giants where baby kelp were grown in a lab and planted in the wild.

    • Discuss the factors that make location selection critical for successful restoration.

    • Have students watch the video on Golden Kelp restoration using Green Gravel method and record details about the restoration activities, including location, focus species, project size, community engagement, results, and future work.

    • Assist students in completing a table with information on various restoration projects across the Great Southern Reef, ensuring they understand the scope and impact of these efforts. They may use this restoration linkpage to help as well as the restoration page on the GSRF website.

10. Social Research Project

  • Activity: Conducting a Social Research Project

    • Explain the importance of understanding public perception in conservation efforts. Guide students through the process of conducting interviews with family, friends, or the school community about their knowledge of kelp forests.

    • Ensure students understand how to record responses, maintain anonymity, and analyse the data collected.

    • Use spreadsheet template to help collate data from the class.

    • Instruct students to visualise their data using graphs or tables and to compare the public’s perceptions with factual information. Assist them in creating an infographic to present their findings, and guide them through a reflection on what they learned from the activity.

11. Classroom Debate

    • Introduce the concept of stakeholders and explain the different roles that students will assume in the debate (e.g., marine scientists, local community representatives).

    • Guide students in researching their stakeholder’s perspective, focusing on the impacts of kelp forest decline and the benefits of restoration.

    • Assist students in preparing their arguments, ensuring they have at least two strong points to present.

    • Facilitate the classroom debate, encouraging respectful discussion and critical thinking. After the debate, lead a discussion on how different stakeholders can work together to achieve the best outcomes for kelp forest restoration.

12. Ocean Optimism

  • Activity: Creating a Classroom Action Plan

    • Emphasise the importance of optimism and proactive action in environmental conservation. Guide students in developing a classroom action plan focused on preserving kelp forests.

    • Encourage students to brainstorm actions they can take, such as promoting sustainable practices or raising awareness in their community.

    • Help them break down each action into manageable steps and consider the resources they’ll need.
