Biomes Intro

Overview

In this lesson (3 of 20) students begin an introductory exploration of biomes and how climate shapes their plant and animal characteristics. Using a mix of guided discussion and a sorting task, students build a clear vocabulary and foundation for later sustainability case studies.

Learning intentions

• Students will explain what a biome is and identify its key characteristics.
• Students will connect climate factors (temperature and rainfall) to biome features.
• Students will describe how human activity can affect biomes using simple evidence-based reasoning.
• Students will communicate biome information clearly using geographical/biome terminology.

Success criteria

• I can explain what a biome is in my own words.
• I can match at least 3 biome types to the climate that supports them.
• I can describe key living features (plants/animals) for a selected biome using clear sentences.
• I can use accurate terms (biome, climate, adaptation, vegetation) in my explanations.

Curriculum links

• Geography: Students assess different approaches to the management and protection of places and environments through analysing human-environment interactions.
• Geography: Students explain how features and characteristics of places and environments change over time, by linking biome traits to climate conditions and seasonal variability.
• Geography: Students select and apply concepts and terminology to communicate geographical information for different audiences.
• Science integration (environmental sustainability): Students analyse the impact of human activity on the natural world when considering how biomes can be affected.

Lesson structure (60 minutes)

1. 0–8 min · Hook + retrieval. Teacher projects a striking image collage of four contrasting environments and asks, “What makes each place feel like a different ‘world’—climate, plants, animals, or something else?” Students do a quick think-write, then share with a partner. Use the introduction slides for the hook image collage and prompts.

2. 8–18 min · Direct teaching (biomes basics). Teacher defines biome (a large regional ecosystem shaped by climate) and models a “climate → vegetation → animals” chain using one example (e.g., grassland or desert). Students take brief guided notes on the chain and underline any unfamiliar terms. Use the introduction slides for the definition, model example, and term callouts.

3. 18–28 min · Mini-lesson: climate indicators. Teacher explains two climate indicators students will use today: average temperature and rainfall/seasonality; provides a simple “climate card” summary for each biome. Students complete a one-minute “check for understanding” by pointing to the correct climate card for the teacher’s statement. Use the introduction slides to display the climate cards and statements.

4. 28–43 min · Core activity: biome sorting & explanation. Teacher distributes the biome sorting worksheet and explains the task: students work in pairs to sort 6–8 “biome clues” (e.g., long dry season, broadleaf trees, very cold winters) into 4 biome categories (tropical rainforest, temperate forest, desert, tundra) and write one evidence sentence for each match. Students then rotate one partner role to test each other’s reasoning. Use the biome sorting worksheet; circulate for misconceptions about rainfall vs temperature and about biome meaning.

5. 43–52 min · Whole-class discussion: human impact link. Teacher prompts: “If people change the climate or land use, what might happen to the biome?” Students contribute one idea each, and the class builds a short “impact ideas” list (e.g., habitat loss, changed rainfall patterns, invasive species). Teacher connects back to sustainability without going deep—this is an introduction lesson. Use the introduction slides for the discussion scaffold (sentence starters and an ideas table).

6. 52–58 min · Plenary: success criteria check. Teacher returns to the biome chain model on the introduction slides and asks students to answer: “Which biome best matches today’s clue set, and why?” Students give a one-sentence response using the sentence frame on the board/slide. Teacher quickly assesses accuracy and vocabulary use.

7. 58–60 min · Exit ticket (quick written evidence). Teacher collects the final portion of the biome sorting worksheet (or a folded “bottom box”) where students complete: “A biome is… Climate affects biomes because…” Teacher checks for correct biome definition and at least one correct climate-to-feature link.

Resources

• the introduction slides
• the biome sorting worksheet
• Coloured pens or pencils for pairing tasks (optional)
• Display board/markers for sentence frames
• Timer visible to students
• A4 laminated “biome clue cards” (optional teacher-made support if available)

Assessment

• Formative during hook: partner sharing and initial misconceptions noted.
• Formative during sorting: teacher observation of pair reasoning and correct climate-to-biome matching.
• Summative for this lesson (lightweight): exit ticket sentence checks for biome definition and one evidence-based climate link.

Differentiation

• Visual supports: the introduction slides includes icons for temperature/rainfall and colour-coded climate indicators.
• Sentence starters on the discussion slide and worksheet help students write evidence sentences (e.g., “Because the climate has…, the vegetation…”).
• Support for learners needing scaffolds: provide a “biome clue to indicator” mini key card during the sorting task (teacher keeps a small set for fast access).
• Extension for advanced learners: after sorting, students add a brief adaptation note—choose one plant or animal trait and explain how it helps survival in that biome.
• EAL: allow drawing + labelled sentences; pre-teach “rainfall”, “seasonality”, “temperate”, and “adaptation” using the slide glossary.

Extension (optional)

• Students write a short reflection on a chosen biome: “I chose ____. One climate feature is ____. One living feature is ____. One way humans could affect this biome is ____. ” (Completed at home or as final 5 minutes next lesson if needed.)
