1. Weather When you hear the word ‘weather,’ what do you think of? Talk to your partner. How many different words can you come up with to describe the weather?

2. Weather Perhaps you came up with some of these: What is your favourite type of weather and why? sun wind r ain thunder snow ice fog cold hot cloudy hail

3. What Is Weather? Weather describes the conditions outside in a particular place at a particular time.  You can see what the weather is like when you look out of the window. It can be hot or cold, wet or dry, windy or calm, sunny or cloudy, or stormy with thunder and lightning.  Weather often changes during the day and from one day to the next. Many different elements create the weather. These include: temperature  wind rain

4. Temperature Temperature is a measure of how hot or cold it is.  The sun provides heat. It can make you feel warm on a sunny day.

5. Wind Wind is moving air. You can’t see it but you can feel it on your face. You can see it blowing things like leaves and trees. The wind can be strong or gentle.

6. Rain Rain Clouds are made up of tiny droplets of water. The water falls to the ground when it rains.  This is called precipitation.

7. What Is Climate? Climate describes the usual weather conditions of an area over a long period of time.  For example: • The United Kingdom has warm summers and cool winters.  • July and August are usually the warmest months in the UK. •December, January and February are often the coldest months. • It rains throughout the year.

8. What Is Climate? Different areas of the world have different climates. These are called climate zones. Countries near the equator have hotter climates while the Arctic and Antarctic have much colder climates.  Climate can affect many things such as which plants can grow.  Many animals are specially adapted to the climate they live in.

9. Let’s explore the weather in different seasons in the UK… The year is divided into four seasons in the UK.  These are spring, summer, autumn and winter.  Each season has different weather patterns. The Seasons

10. Spring Spring is in March, April and May. It is often windy and rainy. The temperature begins to get warmer. It stays lighter for longer in the spring months.

11. Summer Summer is in June, July and August. The sun is much stronger.  The temperature is warmer than in any other season. There is usually less rain too.

12. Autumn Autumn is in September, October and November. The weather turns chillier and windier. There are often lots of rainy days. The days become shorter and the nights last longer in autumn.

13. Winter Winter is in December, January and February. It is often cold and sometimes frosty.   It has to be freezing or below to snow. It is darker for longer during the winter months.

14. The Seasons Seasons in other countries may be very different to the UK. It is summer in Australia in December, January and February. The weather is usually very warm.  Winter in Russia lasts from November to March. There is often thick snow in the winter months.

15. Rainbow red Rainbows can be seen when it is raining in one part of the sky and sunny in another. An arch of different colours appears when sunlight shines through the rain.  Do you know the seven colours of the rainbow? Talk to your partner. yellow orange green blue indigo violet

16. Snow and Hail Snow is frozen water that falls to the ground as soft, white ice crystals.  Tiny ice crystals form high up in the sky when it is very cold. They can form a layer of snow on the ground. Hail is lumps of solid ice that fall from storm clouds.  Hailstones are made when raindrops are blown by wind to the tops of clouds where they freeze. Sometimes hailstones can be big enough to damage cars!

17. Thunderstorms Thunderstorms start inside a cloud.  Lightning happens when water droplets inside a cloud freeze and then crash into each other. This creates a huge spark of electricity that flows between clouds or between a cloud and the ground.  Lightning heats up the air very quickly.  This creates a huge vibration in the air.   We hear this vibration as a loud bang or a rumbling sound.  This is called thunder.

18. Extreme Weather In some places around the world, the weather can be extreme and this can be dangerous.  Extreme weather can include: heatwaves hurricanes very heavy rainfall People need to take special care in extreme weather. It can affect our surroundings as well as us.

19. Weather The weather affects us all. It affects the games you play, the clothes you wear, how you feel, what you eat, what plants can grow and many other things. What is the weather like where you live today? What is your favourite type of weather and why? Weather
