Physical Geography

Curriculum Requirement

Describe and understand key aspects of physical geography, including climate zones, biomes and vegetation belts, rivers, mountains, volcanoes and earthquakes, and the water cycle.

Biomes and Vegetation Belts

What is a Biome?

A biome is a very large area with a specific climate (the typical long-term weather) and unique plants and animals that are adapted to live there.

🐒

The Tropical Rainforest

An incredibly wet and warm biome found near the Earth's equator.
Key Features: Tall, dense trees, huge biodiversity, and high rainfall all year round.

💡 Fun Facts

  • Tropical rainforests like the Amazon cover only about 6% of Earth's surface but are home to more than half of all the world's plant and animal species!
  • The tall trees form a leafy 'canopy' high above the ground, which blocks out most of the sunlight from reaching the forest floor.
  • Many of the plants we use in our homes, for food and medicine, originally came from rainforests, including chocolate, bananas, and pineapples.
❄️

The Arctic Tundra

A vast, cold, and treeless biome found in the Arctic regions.
Key Features: Frozen ground (permafrost), low-growing plants like mosses and shrubs, and animals with thick, warm coats.

💡 Fun Facts

  • In the tundra, the ground beneath the surface, called permafrost, stays frozen all year round, sometimes to a depth of nearly a mile.
  • During the summer, the sun shines 24 hours a day, but it is not strong enough to melt the deep permafrost.
  • Animals like the Arctic fox and ptarmigan have coats that turn white in winter to camouflage them against the snow.
🦒

The African Savanna

A hot, grassy biome with widely spaced trees, found between rainforests and deserts.
Key Features: Large open grasslands, long dry seasons, and herds of large mammals.

💡 Fun Facts

  • The savanna is home to the largest land animals on Earth, including elephants, giraffes, and rhinos.
  • Wildfires are a vital part of its life cycle, clearing away old, dry grass and helping new plants to grow.
  • Some trees, like the baobab, store water in their huge trunks to survive the long dry season.

The Water Cycle

What is the Water Cycle?

The water cycle is the name for the continuous journey that water takes as it moves from the land and oceans, into the air, and back again.

☀️

Evaporation

The process where a liquid, like water, turns into a gas, called water vapour.
Where it happens: From the surface of oceans, rivers, lakes, and even puddles.

💡 Fun Facts

  • The Sun's energy powers evaporation. It gives water molecules the energy to warm up, move faster, and escape into the air.
  • You can see evaporation in action when a puddle dries up on a sunny day.
  • Salt from the ocean does not evaporate with the water, which is why rain is fresh water.
☁️

Condensation

The process where water vapour in the air gets cool and changes back into liquid water droplets.
Where it happens: High up in the atmosphere to form clouds.

💡 Fun Facts

  • A cloud is made of billions of tiny water droplets or ice crystals that have clumped together around microscopic specks of dust or pollen in the air.
  • You can see condensation on a cold day when you breathe out, creating a mini-cloud of water vapour.
  • The dew you see on grass in the morning is another example of condensation happening close to the ground.
🌧️

Precipitation

Water that falls from the clouds towards the ground.
What it includes: Rain, hail, sleet, or snow.

💡 Fun Facts

  • Precipitation happens when the water droplets in a cloud get so big and heavy that the air can't hold them up any more.
  • Raindrops aren't always tear-shaped! Small ones are perfectly round, while larger ones get flattened on the bottom as they fall.
  • Not all rain reaches the ground; some evaporates on the way down, in a phenomenon called 'virga'.
💧

Collection

The process where water from precipitation is collected in rivers, lakes, and oceans.
Where it happens: In bodies of water or underground in the soil.

💡 Fun Facts

  • Some water soaks deep into the ground and is stored there as 'groundwater'.
  • This collected water can then evaporate again, starting the entire cycle over.
  • The same water has been moving around our planet in this cycle for billions of years. The water in your drink could have once been drunk by a dinosaur!

Activities & Reflections

Activities

Biome in a Box

Create a diorama in a shoebox for a specific biome. Use craft supplies and natural materials to show the landscape and the animals and plants that are adapted to live there.

Water Cycle in a Bag

Seal a small amount of water (you can add blue food colouring) in a clear plastic bag and tape it to a sunny window. Pupils can observe evaporation, condensation, and precipitation in miniature.

Journey of a Raindrop

Ask pupils to write or draw a short story about the journey of a single raindrop, describing the different stages of the water cycle it goes through.

Reflections

Self-Reflection (Exit Ticket)

Ask pupils to draw a quick diagram of the water cycle and label the four main stages.

Paired Reflection (Think-Pair-Share)

Ask pupils to discuss with a partner: How is the Arctic Tundra biome different from the African Savanna biome? Name two differences.

Group Reflection

In small groups, ask pupils to imagine they are an animal living in the rainforest. What is the most important feature of the rainforest for their survival?

Whole Class Share-Out

As a class, discuss: The water we drink today has been on Earth for billions of years. What does this tell us about why we need to keep our rivers and oceans clean?
