IELTS Writing Task 1 question

The diagram below shows the process for making a water clock.

Write a report for a university lecturer describing the information below.

HOW TO BUILD YOUR OWN WATER CLOCK

Student answer (Band 5.0)

The diagram illustrates different points how to build your own water. We have total of five stages which start from the tap and end with the plastic bottle (neck cut off).

Overall, in the given diagram we have several major sectors that has its own importance in the proces, we have a tap, cube and plastic bottles. The most beneficial parts are tap and plastic bottle.

We have seven different stages that start from the tap,initial the water step out from the tap and entered to the large plastic bottle,in plastic bottle we have straw,tape and glue if the water filled up in the bottle then extra water will automaticaly released.

Gradually, the next round start from level constant ,there the water is leved up in the bottle after that we have finger away from hole, as we know that we have two bottles the nest process is stepping water from the tiny bottle to large bottle there the water levels per minute.The last stage is empty and repeat process for timings things that held in the the small plastic bottle (neck cut off).

Task Achievement / Task Response: Band 5.0

You identify the water-clock process and mention several relevant components, including the tap, bottles, straw and overflow. You also refer to the final instruction to empty and repeat the process. However, the account only partially describes the diagram: the opening says there are five stages, then later says seven, and the sequence is not reported accurately. In particular, covering the hole with a finger and filling the upper bottle until it overflows are important early steps, while the lower bottle collects the dripping water and is marked with calibration lines. The overview also calls the apparatus “sectors” and does not clearly summarise how it works. Give a concise, accurate overview, then describe all seven stages in order and distinguish the upper and lower bottles.

Coherence and Cohesion: Band 5.0

There is some paragraphing, and the response attempts to move from an introduction and overview to details of the process. Sequencing expressions such as “Gradually,” “after that” and “The last stage” help signal progression. However, the overall organisation is difficult to follow because the introduction says there are five stages, while the body says seven, and the process is not consistently presented in diagram order. Connections between ideas are sometimes unclear: “the next round start from level constant” does not explain how this relates to the previous step, and the sentence about water moving between the bottles is confusing. Plan the report around the actual sequence, using one paragraph for the overview and one or two for the stages, with clear references to the upper and lower containers.

Lexical Resource: Band 5.0

You use some task-related vocabulary, including “tap,” “straw,” “glue,” “plastic bottle” and “levels per minute,” so the reader can recognise the general subject. However, the range is limited and several word choices or collocations make the description unclear. “Different points how to build your own water” is not a natural way to introduce the process, while “cube” does not accurately name a component shown. Phrases such as “water step out” and “stepping water” also obscure the intended actions. Spelling errors, including “automaticaly” and “proces,” further reduce control. Build a small set of precise process terms—such as “attach,” “overflow,” “drip,” “collect” and “mark”—and use them consistently for the apparatus and its stages.

Grammatical Range and Accuracy: Band 5.0

The response attempts to combine ideas in longer sentences, for example with “if” and “after that,” but these structures are often faulty, and sentence control is inconsistent. Errors include “We have total of five stages,” “the next round start,” and “the water is leved up,” where articles, verb forms or sentence construction are not controlled. Some sentences run several actions together without clear punctuation, as in the description beginning “We have seven different stages.” This makes the sequence harder to understand. Practise writing short, accurate process sentences first, using the present simple passive where appropriate—for example, “The upper bottle is attached to the stand”—then add subordinate clauses only when their relationships are clear.
