HOW TO BUILD YOUR OWN WATER CLOCK

Student answer (Band 6.5)

The diagram presents the process of manufacturing a water clock.

Overall, it is clear that there are seven stages in the process of constructing a water clock, beginning with water filling in bottle and ending with a fully functioning water clock.

To begin with, a plastic bottle is placed in a stand with the help of tape then water is usually added till the top through the tap. water level is predicted through the straw which is fitted in bottle with the help of glue. Moreover, there should be a hole at the bottom of bottle, but before adding water the hole is covered with a finger until water starts overflowing through straw. In the next step a plastic bottle without neck is placed under the bottle to use as a container to check the levels per minute after seeing the water level constant, finger is put away from the hole. Now in the 6 step of building a water clock, as the water starts dripping in the container levels per minutes are checked. Last but not the least this process is repeated many time for timing things. As a result, the water clock is ready.

Task Achievement / Task Response — Band 6.5

The response covers all stages of the process, from the initial setup to the final timing function. The overview is clear and identifies the number of stages. However, the description of the steps is somewhat mechanical and lacks a logical flow in terms of how the components interact. For instance, the explanation of the hole and the finger is slightly confusing and could be more precisely described to ensure the reader fully understands the mechanics of the water clock. While all parts of the task are addressed, the development of the process description could be more refined to achieve a higher band.

Coherence and Cohesion — Band 6.5

The response is organized into a logical sequence, moving from the initial setup to the final operation. Cohesive devices such as 'To begin with', 'Moreover', and 'In the next step' are used to guide the reader through the process. However, the paragraphing is insufficient; the entire body of the report is contained in a single paragraph, which hinders the overall structure. Additionally, some transitions feel a bit repetitive or forced. Improving the paragraph structure and using a wider variety of linking words would enhance the flow and clarity of the report.

Lexical Resource — Band 6.5

The vocabulary used is generally adequate for the task, with terms like 'manufacturing', 'constructing', and 'functioning' used appropriately. However, there are some inaccuracies in word choice and collocation, such as 'water filling in bottle' (should be 'filling the bottle with water') and 'timing things' (which is vague). The range of vocabulary is somewhat limited, and the student relies on basic phrasing to describe the technical steps. To improve, the student should focus on using more precise technical terminology and improving collocations related to process descriptions.

Grammatical Range and Accuracy — Band 6.5

The response contains a mix of simple and complex sentence structures. There are several grammatical errors, particularly regarding articles ('in a stand', 'at the bottom of bottle') and prepositions. Some sentences are slightly awkward, such as 'water level is predicted through the straw which is fitted in bottle with the help of glue'. While these errors do not significantly impede communication, they occur frequently enough to prevent a higher score. Focusing on article usage and sentence construction would help improve the overall grammatical accuracy.
