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

HOW TO BUILD YOUR OWN WATER CLOCK

Student answer (Band 6.0)

The diagram displays the process for making a water clock, showing several stages involved in this production.

Overall, the process consists of total of seven stages, beginning with turning on the tap and ending with emptying the plastic bottle and repeating the process to check the timings, while the plastic bottle is attached with the stand using the tape.

The first step starts with turning on the tap and filled the plastic bottle with water, the fingers are place over the bottom of the bottle to stop the leakage.The next step involves to filled up the bottle till the top level in order to overflowing through the straw. Straw was attached with the plastic bottle using glue. After the water overflows, the level of water is maintained at a constant level by means of the straw.

In the next stage, the fingers are pulled away from the hole to transfer the water in to the next off necked cut bottle, which is marked with certain levels to check the water level per minute. The last step involves emptying the second bottle and repeating the same process for timing things.

Task Achievement / Task Response: Band 6.5

The report gives a clear overview of the seven-stage sequence, identifying the tap being turned on as the start and emptying and repeating the process as the end. It also includes key construction details, such as the straw fixed with glue and the upper bottle attached to a stand with tape. Most stages are represented, including the overflow and the marked lower bottle. However, some details are unclear or imprecise: “the fingers are place over the bottom” does not clearly explain that a finger covers the hole, and “check the water level per minute” does not accurately convey that the markings show levels per minute. The account is relevant and covers the process, but these points need clearer, more precise description.

Coherence and Cohesion: Band 6.5

The response is organised into an introduction, an overview and two paragraphs describing the stages, and the sequence is generally easy to follow. Time markers such as “The first step,” “The next step” and “In the next stage” help guide the reader through the process. The overview also usefully identifies the beginning and ending. However, some links between actions are awkward or unclear: the first paragraph combines filling the bottle and covering its hole in a way that makes their order difficult to follow, while “After the water overflows” does not clearly connect the constant water level to the next action. Use more precise sequencing and references to the upper and lower bottles to make progression smoother and less dependent on repeated “step” phrases.

Lexical Resource: Band 6.0

The response uses an adequate range of process vocabulary, including “attached,” “overflows,” “constant level,” “marked” and “repeating,” which helps communicate the main stages. It also attempts more specific terms such as “production” and “transfer.” However, several choices are inaccurate or unnatural for this diagram: “production” is less suitable than “construction” or “process,” “filled up … till the top level” is imprecise, and “next off necked cut bottle” is difficult to understand. “Check the water level per minute” also does not express the function of the calibration marks clearly. Aim for accurate collocations and concise labels for the apparatus, such as “lower bottle with its neck removed” and “markings indicating levels per minute.”

Grammatical Range and Accuracy: Band 5.5

There is a mix of simple and more complex sentence forms, including clauses with “while,” “in order to” and “which,” and the overall meaning is usually recoverable. However, some errors in verb forms, agreement and sentence construction remain. For example, “The first step starts with turning on the tap and filled” shifts from a gerund to a past-tense verb; “the fingers are place” needs a past participle; and “involves to filled up” uses an incorrect verb pattern. The sentence beginning “The next step involves” also needs clearer grammatical coordination. Punctuation is occasionally faulty, as in “leakage.The next step,” where a space is missing after the full stop. Check parallel verb forms and use “involves filling” or “involves removing” consistently.
