Lesson: Biomes and Vegetation

Year: 6 | Subject: Geography | Time Allocation: 100%

Class/Set: ____________ Date/Term: ____________

LO (WALT): To describe and understand the key characteristics of global biomes and their specific vegetation.

Success Criteria (WILF):

1. I can define a 'biome' as a large distinct community of flora and fauna.
2. I can locate major biomes on a world map using climate zones as a guide.
3. I can explain how specific vegetation has adapted to the climate of its biome.

1. Starter (15%)

• Activity: 'Climate Connections' Retrieval.
• Display: Images of a desert, a tropical rainforest, and the Arctic tundra.
• Question: Ask students to list three adjectives to describe the climate (temperature and rainfall) for each image on mini-whiteboards.
• Challenge: Can students identify which of these areas would have the highest biodiversity? Introduce the term 'biodiversity' if unknown.

2. Main Activity (70%)

Teacher Input:

• Define: Explain that a biome is a large geographical area of distinctive plant and animal groups which are adapted to that particular environment.
• Examine: Use a world map to show the distribution of biomes. Point out the latitudinal patterns (e.g., rainforests near the Equator, Tundra near the poles).
• Contrast: Compare the 'Tropical Rainforest' biome with the 'Hot Desert' biome. Focus on Tier 3 vocabulary: Precipitation, Humidity, and Adaptation.
• Model: Show a 'WAGOLL' (What A Good One Looks Like) of a vegetation analysis. Demonstrate how a cactus stores water in its succulent stem to survive low precipitation.

Student Task:

• Task 1 (Mapping): Label a blank world map with the following biomes: Tropical Rainforest, Hot Desert, Savannah, and Tundra. Use a colour-coded key to show different climate zones.
• Task 2 (Classification): Complete the 'Vegetation Match' table. Students must match the plant (e.g., Liana, Orchid, Baobab tree, Moss) to the correct biome and provide one reason why it grows there.
• Task 3 (Reasoning): Write a short paragraph explaining why vegetation in the Tundra is low-growing and moss-like, compared to the 'Emergent Layer' trees in a rainforest. Use the word 'permafrost' in the explanation.
• Support: Provide a 'Word Bank' containing: humidity, equator, arid, canopy, adaptation, and precipitation.

3. Plenary (15%)

• Check: 'Biome Bingo'. Read out a description (e.g., "This biome has high temperatures and high rainfall all year round"). Students must name the biome.
• Consolidate: Reflect on the LO. Ask students: "If the global temperature rises by 2°C, how might the boundaries of these biomes change?"

4. Resources

• World Map templates and coloured pencils.
• Biome Profile Fact Sheets.
• 'Vegetation Match' Table (Student Version).
• Mini-whiteboards and pens.

⚠ TEACHER’S GUIDANCE

• Pedagogical Pulse: 💡 Ensure students do not confuse 'Biomes' with 'Countries'. Reinforce that a single biome can span multiple continents. When discussing vegetation, encourage students to think about 'cause and effect'—how the physical climate causes the biological adaptation.

Task 1 Answer (Mapping):

• Rainforest: Central South America (Amazon), Central Africa (Congo), SE Asia.
• Hot Desert: Northern Africa (Sahara), Central Australia.
• Tundra: Far Northern Canada, Russia, and Greenland.
• Savannah: Central/Eastern Africa, parts of South America.

Task 2 Answer (Classification):

Plant	Biome	Reason for Adaptation
Liana	Rainforest	Climbs trees to reach sunlight in the dark canopy.
Cactus	Hot Desert	Succulent stem to store water; spines to reduce transpiration.
Baobab	Savannah	Thick bark to protect against seasonal fires; water storage in trunk.
Moss	Tundra	Low-growing to avoid harsh, cold winds and survive on thin soil.

Task 3 Answer (Reasoning):

• Expected Response: Tundra vegetation is small and low-growing because the ground is often frozen (permafrost), preventing deep roots. The temperature is too cold for large trees. In contrast, rainforests have high precipitation and heat, allowing trees to grow very tall to compete for sunlight.
