Exit quiz

______ occurs when land that is usually dry is covered with water, often as a result of heavy rain.
- 'Flooding' ✓
What can happen to crops when they are waterlogged?
- They are damaged as the air cannot get to the roots. ✓
- The crops grow really well as they need lots of water.
- Nothing, as crops are plants and they need water.

- Farmers use more water on their crops which causes fields to flood.
- Warmer air can hold more water. The extra water in the air falls as extra rain. ✓
- People are hot so they need more rain to keep themselves cool.
- Warmer air makes the land turn to water.

Lesson Details

Key learning 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.
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.

Common misconception

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

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.
