     2. The second fact is about the concept of biomimicry, where scientists and engineers draw inspiration from nature to design sustainable solutions. For instance, the development of solar panels was inspired by the process of photosynthesis in plants.
   • The teacher asks the students if they can think of any other examples where nature has inspired sustainable solutions. This activity encourages the students to think creatively and to recognize the potential of Biology in sustainability.

Development (20 - 25 minutes)

1. Understanding Sustainability and its Importance (5 - 7 minutes):

   • The teacher starts by explaining the definition of sustainability as the ability to meet the needs of the present without compromising the ability of future generations to meet their own needs.
   • The teacher presents multiple real-life examples that illustrate the importance of sustainability, such as the depletion of natural resources, rising global temperatures, and loss of biodiversity.
   • The teacher emphasizes that unsustainable practices can lead to long-term negative consequences, and that promoting sustainability is crucial for the well-being of both current and future generations.

2. Exploring Different Aspects of Sustainability (5 - 7 minutes):

   • The teacher presents the three pillars of sustainability: environmental, social, and economic.
   • The teacher explains that sustainable practices should not only protect the environment and conserve resources (environmental pillar), but also ensure social equity and well-being (social pillar), and promote economic growth that is not at the expense of the environment and society (economic pillar).
   • The teacher uses simple, relatable examples to explain each pillar. For instance, in the context of agriculture, sustainable practices could include using natural fertilizers and pesticides (environmental), paying fair wages to workers (social), and ensuring the long-term profitability of the farm (economic).

3. Applying Biology in Sustainability (10 - 12 minutes):

   • The teacher introduces the role of Biology in sustainability, explaining that the principles of Biology help us understand how organisms and ecosystems function and interact. This knowledge can then be used to develop and implement sustainable solutions.
   • The teacher delves into several examples of how biological knowledge is applied in different sectors to promote sustainability:
     1. In agriculture, biological pest control methods can be used instead of chemical pesticides. This involves introducing natural predators or disease to control pests, which is a more sustainable and environmentally friendly approach.
     2. In energy, the teacher explains the role of photosynthesis in producing biomass, which can be used as a renewable energy source. Additionally, the teacher can discuss the potential of biofuels, which are derived from living organisms or their metabolic by-products, in reducing greenhouse gas emissions.
     3. In waste management, the teacher can discuss the process of composting, where organic waste is decomposed and recycled into nutrient-rich soil. This biological process reduces the amount of waste going to landfills, which can be a significant source of greenhouse gases.
   • After each example, the teacher encourages students to discuss the potential benefits and challenges of implementing these sustainable practices. This promotes critical thinking and a deeper understanding of the complexities of sustainability.

4. Interactive Activity (5 - 7 minutes):

   • To make the learning process more engaging, the teacher proposes an interactive activity where students will work in small groups to design their own sustainable solution for a given problem.
   • The teacher provides each group with a different problem scenario related to sustainability, such as 'How to make a school garden more sustainable?' or 'How to reduce plastic waste in the school cafeteria?'.
   • Students are given a few minutes to discuss and draw their ideas on a piece of paper. The teacher walks around the room, providing guidance and clarifying doubts.
