Extreme weather: flooding (non-statutory Climate Change & Sustainability)

Living things and the environment

Unit Summary

This unit focuses on grouping living things and using classification keys to identify and name them in various environments. It explores how environmental changes can pose dangers to organisms. Emphasis is on asking questions, collecting data, and using evidence to support conclusions.

Lesson Summary

You will learn to explain why more extreme weather leading to flooding can affect environments.

Key Notes

  • Flooding occurs when an area of land is covered with water, especially from rain.
  • Floods can cause damage to crops, when air cannot get the the roots and they rot.
  • Floods affect some parts of the world more than others.
  • The air all around our planet is warming up, and warmer air can hold more water.
  • The extra water in the air falls as extra rain, and can cause flooding.

Vocabulary To Learn

  • flooding: Flooding is the covering or submerging of normally dry land with a large amount of water.
  • crop: A crop is a plant that is grown to be sold, often as food.
  • waterlogged: Land which is waterlogged is full of water or almost covered by a layer of water.
  • extreme: Extreme means very large in amount; much more than normal.
  • climate: Climate is weather patterns over a long period of time.

Common Mistakes To Avoid

  • Children may think that it doesn't rain very much in countries with warmer climates.

3 Quick Questions (With Answers)

1. Explain the scientific idea in this lesson using two key points.

Flooding occurs when an area of land is covered with water, especially from rain. Floods can cause damage to crops, when air cannot get the the roots and they rot.

2. Define this scientific word and use it in context. 'flooding'

Flooding is the covering or submerging of normally dry land with a large amount of water. Include the word in a full scientific explanation, not as a single label.

3. Correct this common scientific misunderstanding.

Mistake: Children may think that it doesn't rain very much in countries with warmer climates. Correction: Through the lesson, and drawing on children from other countries in your class, discuss the rainfall and weather to illustrate this is not the case. The data within the slides will help illustrate this.
