Contextualization

Aquatic biomes, including both freshwater and marine environments, are a vital part of our planet's biosphere. They cover about 75% of the Earth's surface and are home to an incredible diversity of species, many of which are still undiscovered. But what exactly are biomes? A biome is a large geographical area characterized by its distinctive plant and animal communities, as well as its climate.

Aquatic biomes are defined by the type of water they contain and can be broadly classified into two categories: freshwater and marine. Freshwater biomes include lakes, rivers, ponds, and wetlands, while marine biomes consist of oceans, coral reefs, and estuaries. Despite their differences, these biomes share certain characteristics, such as being rich in nutrients and hosting a wide variety of life forms.

Aquatic biomes play a crucial role in maintaining the Earth's climate and weather patterns. They are the primary source of the water that we use for drinking, farming, and industry. Moreover, they absorb and store large amounts of carbon dioxide, helping to mitigate the effects of climate change.

Unfortunately, these biomes are also under threat from human activities. Pollution, overfishing, habitat destruction, and climate change are all putting immense pressure on aquatic ecosystems. It's important that we understand the complexity and significance of these biomes, and our impact on them, so that we can work towards their conservation and sustainable use.

Practical Activity

Activity Title: "Exploring Aquatic Biomes: Creating an Underwater Ecosystem"

Objective of the Project:

The goal of this project is to create a model of an aquatic biome, either freshwater or marine, and examine how its various components (plants, animals, water, etc.) interact with each other and with the environment. By doing so, you will gain a deeper understanding of the complexity and fragility of these ecosystems, and how they are impacted by human activities.

Detailed Description of the Project:

In this project, each group will create a model of an aquatic biome of their choice. The model should accurately represent the key features and organisms of the chosen biome. The students will then analyze and discuss their model, identifying the different components of the ecosystem and describing their interactions. Finally, they will consider the potential impacts of human activities on their chosen biome.

Necessary Materials:

1. Large plastic container or aquarium (to create the model)
2. Rocks, sand, and soil (for the bottom of the model)
3. Water (to fill the model)
4. Plants and small, non-living, plastic animals (to populate the model)
5. Research materials (books, web resources, etc.)
6. Notebooks and pens (for taking notes)

Detailed Step-by-Step for Carrying Out the Activity:

1. Research: Begin by researching the characteristics and inhabitants of your chosen aquatic biome. This will help you in creating an accurate model. Use the provided resources and any other relevant sources.

2. Planning: Sketch a plan for your model, indicating where different elements (plants, animals, etc.) will be placed.

3. Creating the Model: Build your model in the plastic container or aquarium. Start by adding the rocks, sand, and soil to create the bottom. Fill the container with water. Add the plants and plastic animals according to your plan.

4. Observing: Once your model is complete, spend some time simply observing it. Take note of the interactions between the different components. How do the plants and animals interact with each other and with the environment? What role does each component play in the ecosystem?

5. Discussion: As a group, discuss your observations and findings. Use your research to explain why certain interactions are occurring and what they mean for the overall health of the ecosystem.

6. Human Impact: Consider how human activities might impact your chosen aquatic biome. This could include pollution, overfishing, or habitat destruction. Discuss the potential consequences of these impacts on the ecosystem.

7. Reporting: Finally, prepare a report detailing your project. The report should be structured into four main sections: Introduction, Development, Conclusions, and Used Bibliography.

   a. Introduction: Give an overview of your chosen aquatic biome, why you chose it, and what you aimed to learn from the project.

   b. Development: Detail the steps you took to research, plan, create, and observe your model. Discuss your findings and any interesting observations or insights you gained.

   c. Conclusions: Summarize the main points of your project. What did you learn about your chosen aquatic biome and its inhabitants? What did you learn about the interactions between the components of the ecosystem? What are the potential impacts of human activities on your chosen biome?

   d. Used Bibliography: List all the resources you used for your research, including books, web pages, and videos.

The project should take approximately two to four hours per student to complete and be delivered within one week from the time of assignment. It should be carried out in groups of 3 to 5 students. At the end of the project, each group will present their model and their findings to the class.
