Explaining the Water Cycle: Nature's Recycling Process
The water cycle, a crucial natural phenomenon, illustrates how water circulates in the environment. Evaporation, condensation, and precipitation are key stages that define this continuous process, sustaining life on Earth.

Today you are going to write another explanation text about a topic of your choice. You can choose to write about whatever you would like. You will need to research the topic you want to write about, then use the features we have looked at to write your text.
Use these headings to help you write the explanation text. Title Introduction Main body of text Conclusion Technical language
These are the features you need to include Written in the present tense, in formal language Text arranged into numbered points Sub-headings to separate sections of text Time connectives, such as: first, then, next, later, finally. Technical vocabulary (sometimes in bold), for example: if the text is about how a car is made, it may include words such as 'ignition', 'engine' and 'bonnet' Glossary to explain technical vocabulary Diagrams with labels Pictures with captions
Title (does this clearly show what you are explaining?): How to change your television channel using the Tellyscope 2000 . Introduction (How will you introduce your explanation text?) Start with a rhetorical question, explain how my machine can help solve a problem, explain how it will change people s lives.
Main body of text (full explanation of how machine works) Include detailed explanation of what you have to do to make the machine work and how it functions. Use a range of technical language here and make sure you have included causal and time conjunctions
Conclusion Explain how this machine will change people s lives. What to do if the machine does not work or is faulty. Technical vocabulary Make a list of the technical language you are going to include.
The water cycle The water cycle is also known as the hydrological cycle. There is the same amount of water on the Earth now as there was when the Earth began. The water cycle is how the earth's water recycles itself. The cycle includes precipitation, evaporation, condensation, and transpiration. Earth's water keeps changing from liquid water to vapour and then back again. This cycle happens because of the sun's heat and gravity. How does the Water Cycle work? 1. First of all, water molecules from lakes, rivers, streams, reservoirs, and the sea get heated up by the sun and then turn into vapour that rises into the air. 2. Next, these water molecules form into clouds, this is because a process called condensation occurs. 3. When the air and the water cool, they form drops of water which then fall to the earth as rain. If they are frozen, they become snow or sleet. 4. Once the water reaches the ground, it can flow across the land until it reaches rivers, lakes, streams, or the sea. It can also sink into the ground and flow because of gravity through gaps in rock, gravel and sand. Because of this, it reaches these bodies of water too. 5. Now the cycle begins again, when water is evaporated once more. Why is water important? Many of us think water will always be there for us when we want it. Without water, living things would die. You will die if you go without water for more than a week. Plants will die without water and that would kill all of the animals that eat the plants.
How to Fly a Hot Air Balloon A hot air balloon consists of a basket, four big gas tanks, a burner and the balloon or envelope . First, the pilot puts four nylon poles into sockets on top of the basket. Then she puts the burner on top of the poles. Next, she connects the cables to the burner frame. The cables also go under the basket in order to hold everything together. After this, she connects the hoses from the full gas tanks to the burner so that she can test it. Next, two people hold the mouth of the balloon open while it is filled with cold air from the fan until it is quite fat and tight. Now for the difficult bit. The pilot lies on the ground, half in the basket. She turns on the gas burner and points the flame into the mouth of the balloon. This is so that the balloon slowly stands up. When the pilot is ready to go, she heats up the air in the balloon a bit more. This results in the air in the balloon to be hot enough to get the balloon to rise off the ground.
You need to present your work in an interesting way. As explanation texts often have technical drawings and pictures, you can present your text on a poster with drawings of your contraption. You could make a powerpoint presentation like this one to present your explanation text. How you choose to present your work is up to you, but you will have two days to write your explanation and find a way of presenting it, so your work should be accurate and well presented.
Use the success criteria to help you I have written in the present tense, in formal language I have arranged text into numbered points I have included sub-headings to separate sections of text I have used time connectives, such as: first, then, next, later, finally. I have included technical vocabulary (sometimes in bold), for example: if the text is about how a car is made, it may include words such as 'ignition', 'engine' and 'bonnet I have included a glossary to explain technical vocabulary I have added diagrams with labels
