Introduction

Duration: (10 - 15 minutes)

The purpose of this stage of the lesson plan is to capture students' interest and provide an initial context that positions the importance of studying biomes. By presenting curiosities and interesting facts, the aim is to engage students and prepare them for a more detailed exploration of the characteristics and meanings of each biome.

Context

Begin the class by explaining that biomes are large areas of the planet that share similar climatic characteristics, flora, and fauna. Each biome has a unique biodiversity and plays a crucial role in the ecological balance of the Earth. Highlight that understanding biomes helps to comprehend how environmental conditions affect life and ecosystems around the world.

Curiosities

Did you know that the Amazon Rainforest, one of the most well-known biomes, is responsible for about 20% of the oxygen produced by photosynthesis on Earth? Or that deserts, despite their arid appearance, host a surprising variety of life adapted to extreme conditions? These curiosities show the diversity and importance of biomes on our planet.

Development

Duration: (60 - 70 minutes)

The purpose of this stage of the lesson plan is to provide a detailed and comprehensive understanding of the main biomes of the world. This section aims to deepen students' knowledge about the characteristics, locations, flora, and fauna of each biome. The proposed questions help consolidate learning and encourage the application of acquired knowledge.

Covered Topics

1. Grasslands: Explain the characteristics of grasslands, which are areas dominated by grasses and other herbaceous plants. Highlight their importance for agriculture and the types of grasslands, such as prairies and pampas, mentioning their geographical locations. 2. Deserts: Detail the characteristics of deserts, emphasizing low precipitation and extreme temperatures. Explain how plants and animals adapt to these conditions. Give examples of famous deserts, such as the Sahara and the Atacama Desert. 3. Temperate Forest: Describe temperate forests, which have well-defined seasons. Talk about the diversity of trees, such as oaks and beeches, and the varied fauna. Geographically locate these forests in regions like North America and Europe. 4. Tropical Forest: Explain the characteristics of tropical forests, highlighting the high biodiversity and constant precipitation. Discuss the ecological importance, mentioning the Amazon and other large tropical forests in Southeast Asia and Africa. 5. Savannah: Describe savannahs, which are biomes with predominantly grass vegetation and some sparse trees. Detail the climate with well-marked dry and rainy seasons and mention the typical fauna, including large mammals. Examples include the African savannah. 6. Tundra: Explain the tundra, characterized by cold temperatures, permafrost, and low-growing vegetation such as mosses and lichens. Geographically locate this biome in polar regions of the northern hemisphere, such as Alaska and Siberia. 7. Taiga: Detail the taiga, or boreal forest, which is dominated by conifers like pines and firs. Explain the cold climate with long winters and short summers. Geographically locate the taiga in areas such as Canada, Russia, and Scandinavia.

Classroom Questions

1. 1. What are the main differences between a temperate forest and a tropical forest? 2. 2. How do desert plants and animals adapt to the extreme conditions of this biome? 3. 3. Why do tundra and taiga have more limited biodiversity compared to other biomes?

Questions Discussion

Duration: (10 - 15 minutes)

The purpose of this stage of the lesson plan is to provide an opportunity to review and consolidate students' learning through a detailed discussion of the proposed questions' answers. This moment allows students to clarify doubts, connect concepts, and actively engage in applying the knowledge acquired about biomes.

Discussion

• 1. What are the main differences between a temperate forest and a tropical forest?

• Temperate forests have well-defined seasons, with cold winters and hot summers, while tropical forests have a warm and humid climate year-round. Biodiversity is greater in tropical forests due to the constant availability of water and stable temperatures, while temperate forests have a variety of species adapted to seasonal changes. Vegetation in tropical forests is dense and multi-layered, whereas in temperate forests, it is sparser with deciduous trees that lose their leaves in autumn.

• 2. How do desert plants and animals adapt to the extreme conditions of this biome?

• Desert plants, such as cacti, have adaptations like reduced leaves into spines to minimize water loss and deep roots to reach underground water reserves. Animals have adapted with nocturnal behaviors to avoid daytime heat and abilities to store water and nutrients. Examples include camouflage to protect themselves from predators and the capability to live with little water for long periods.

• 3. Why do tundra and taiga have more limited biodiversity compared to other biomes?

• Tundra and taiga have more limited biodiversity due to extreme climatic conditions. The tundra has permanently frozen soil (permafrost), which prevents many plants from growing, while the taiga has long and harsh winters that limit plant and animal life. The short growing season and low primary productivity result in fewer resources available to support a variety of species.

Student Engagement

1.  Questions for discussion: 2. 1. What are some examples of specific adaptations you know about in plants or animals from the studied biomes? 3. 2. How might climate change affect each of the discussed biomes? 4. 3. Which biome do you find most interesting and why? 5. 4. How do biomes influence human life and the economy of the regions where they are located? 6. 5. How can the conservation of biomes help preserve global biodiversity?

Conclusion

Duration: 10 - 15 minutes

The purpose of this stage of the lesson plan is to recap the main points studied, reinforcing the acquired knowledge. This moment allows students to consolidate information, understand the relevance of the content to their lives, and see how theory applies in practice, encouraging a deeper and more lasting understanding of the topic addressed.

Summary

• Biomes are large areas of the planet with similar climatic characteristics, flora, and fauna.
• Grasslands are dominated by grasses, which are important for agriculture.
• Deserts have low precipitation and extreme temperatures, with adapted flora and fauna.
• Temperate forests have well-defined seasons and a diversity of deciduous trees.
• Tropical forests have high biodiversity and constant precipitation, like the Amazon.
• Savannahs are characterized by grasses and some sparse trees, with well-marked dry and rainy seasons.
• Tundra has cold temperatures, permafrost, and low-growing vegetation found in polar regions.
• Taiga, or boreal forest, is dominated by conifers, with long winters and short summers.

The lesson connected the theory about the characteristics of biomes with clear and direct examples of each, showing how environmental conditions affect life and ecosystems. Discussions about the adaptations of plants and animals, as well as the geographical location of each biome, helped illustrate their practical applications in understanding the natural world.

Understanding biomes is crucial for comprehending the biodiversity and ecosystems of the planet. For example, knowing that the Amazon Rainforest is a major producer of oxygen helps us value its conservation. Additionally, knowing about deserts shows how life can adapt to the most extreme conditions, highlighting the resilience of nature and the importance of protecting these unique environments.
