Now, let’s look at sample essays for different band scores.
Sample Essay 1 (Band 8-9)
Space technology has emerged as a promising solution to tackle the global water crisis, and I strongly agree that it can play a crucial role in addressing this pressing issue. This essay will explore how satellite technology and space-based observations contribute significantly to water management and conservation efforts.
Firstly, space technology provides invaluable data for monitoring and managing water resources on a global scale. Satellites equipped with advanced sensors can track changes in water bodies, measure soil moisture levels, and detect underground water reserves. This information is crucial for policymakers and water management authorities to make informed decisions about water allocation and conservation strategies. For instance, NASA’s GRACE (Gravity Recovery and Climate Experiment) satellites have been instrumental in mapping groundwater depletion in various regions, allowing for timely interventions to prevent water shortages.
Moreover, space-based observations enable accurate weather forecasting and climate modeling, which are essential for predicting and mitigating water-related disasters. By analyzing atmospheric data collected from satellites, scientists can forecast droughts, floods, and other extreme weather events with greater precision. This foresight allows communities to prepare for water-related challenges and implement appropriate measures to conserve water resources. For example, farmers can adjust their irrigation practices based on satellite-derived weather predictions, leading to more efficient water use in agriculture.
Additionally, space technology facilitates the development of innovative water purification and desalination techniques. Research conducted in space stations has led to advancements in water recycling systems, which can be adapted for use on Earth. These technologies can help address water scarcity in regions with limited freshwater resources by making seawater and contaminated water potable. The International Space Station’s water recovery system, which recycles urine and sweat into drinkable water, serves as a model for developing similar systems for use in water-scarce areas on Earth.
While some may argue that investing in space technology diverts resources from more immediate water management solutions, the long-term benefits of space-based innovations far outweigh the initial costs. The global perspective and technological advancements gained from space exploration are invaluable in addressing water scarcity on a planetary scale.
In conclusion, space technology plays a vital role in addressing global water scarcity by providing crucial data for water resource management, improving weather forecasting, and inspiring innovative water treatment solutions. As we continue to face growing water challenges, harnessing the power of space technology will be essential in ensuring sustainable water management for future generations.

Space Technology Addressing Water Scarcity
Sample Essay 2 (Band 6-7)
In recent years, the use of space technology to solve global problems has become more common. I agree that it can help address water scarcity to some extent, but I think there are limitations to its effectiveness.
One way space technology can help is through satellite monitoring. Satellites can observe large areas of land and water, providing information about water sources and usage. This data can help governments and organizations make better decisions about water management. For example, satellites can detect underground water reserves or track changes in river flows, which is useful for planning water distribution.
Another benefit of space technology is improved weather forecasting. By using satellite data, scientists can predict rainfall patterns and droughts more accurately. This information is valuable for farmers and water authorities to plan their water use. It can also help in preparing for water-related disasters like floods.
Space research has also led to the development of water purification technologies. Some water filtering systems used in space stations have been adapted for use on Earth, helping to clean contaminated water in areas where clean water is scarce. This shows how space technology can have practical applications for solving water problems.
However, there are limitations to what space technology can achieve. It cannot directly create new water sources or transport water to dry areas. The cost of space technology is also very high, which means it might not be accessible to all countries, especially those that need it most.
In conclusion, while space technology can contribute significantly to addressing water scarcity through monitoring, forecasting, and inspiring new technologies, it is not a complete solution. It should be used alongside other methods of water conservation and management for the best results.

Explanation of Band 6-7 Score
This essay demonstrates the characteristics of a Band 6-7 score for the following reasons:
Task Response: The essay addresses the task and presents a clear position, but the discussion of the extent of agreement could be more developed.
Coherence and Cohesion: The ideas are organized logically, but the links between paragraphs could be stronger. Some cohesive devices are used, but not always effectively.
Lexical Resource: There is a sufficient range of vocabulary related to the topic, but it lacks the sophistication and precision of higher band scores.
Grammatical Range and Accuracy: The essay uses a mix of simple and complex sentence structures, with some errors that do not impede communication.
Development of Ideas: Main points are supported with relevant ideas, but the examples and explanations could be more detailed and specific.
Sample Essay 3 (Band 5-6)
Water scarcity is a big problem in many parts of the world. Some people think space technology can help solve this problem. I partly agree with this idea.
Space technology can be useful for water scarcity in some ways. Satellites in space can take pictures of Earth and show where water is located. This information helps people know where to find water. Also, satellites can help predict weather, which is important for knowing when it will rain.
Another good thing about space technology is that it can help clean water. Scientists who work on space stations have made special filters for water. These filters can be used on Earth to make dirty water clean for people to drink.
However, space technology is very expensive. Many poor countries cannot afford to use it. Also, it cannot make new water appear in places where there is no water at all.
In my opinion, space technology is helpful but not enough to solve all water problems. We need to use other ways to save water too, like fixing leaky pipes and using less water in our daily lives.
In conclusion, I think space technology can help with water scarcity, but it is not the only solution. We need to use it together with other methods to really solve the problem of water scarcity.
