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 illustrate the process for making a water clock.

In the diagram water clock made by two bottles , straw and stand on which two bottles are hold.

In making first take two bottles and hold on the stand of the edge and than the lower bottles neck cut off . Secondly make hole under the upper bottle and than putt the straw on upper bottle with the help of glue.

In working process first on the tap water and cover the hole with finger . Thirdly fill top bottle to overflow and wait until level constant if water will be more than constant level its automatically remove from the bottle with the help of straw . After level constant finger away from hole. On the second bottle their are levels per minute printed . This is how water clock build and work. If water bottles are filled with time and than empty and repeat process for timing things .

This is how to build your own water tank.

Task Achievement / Task Response: Band 5.0

You cover the main idea that the diagram shows both construction and operation, and you include several relevant stages: making a hole, attaching the straw, allowing water to overflow, and using the lower bottle’s markings. However, the account is only partly accurate and developed. The stand and the bottles’ arrangement are described unclearly, and “hold on the stand of the edge” does not explain that the upper bottle is taped to the stand while the cut-neck bottle sits below it. The sequence is also confused: the tap is turned on and the hole covered before the upper bottle is filled. Your final reference to a “water tank” contradicts the task. A clearer overview and a more precise, complete sequence would strengthen the report.

Coherence and Cohesion: Band 5.5

The response has a basic overall order: it first mentions the equipment and construction, then describes how the clock works. Sequencing expressions such as “Firstly,” “Secondly,” “Thirdly,” and “After” help the reader follow some stages. However, progression is uneven because the construction and operating instructions are mixed together, and the sequence markers do not consistently match the diagram’s order. For example, “In working process first on the tap water” is followed by “Thirdly fill top bottle,” leaving the relationship between steps unclear. Several ideas are joined in long, loosely connected sentences, while paragraphing is limited. Group the construction steps separately from the operating stages and use clear references to connect each step.

Lexical Resource: Band 5.0

You use some task-relevant vocabulary, including “straw,” “stand,” “overflow,” “hole,” and “levels per minute,” so the reader can identify the main components and actions. However, the range is limited and several word choices or combinations are inaccurate, which sometimes makes the description difficult to interpret. “Water tank” is not an appropriate name for the device, and “two bottles are hold” does not clearly describe how they are supported. Phrases such as “on the second bottle their are levels per minute printed” also lack precise vocabulary for the markings. Aim for accurate process language and natural collocations, such as “attach,” “secure,” “calibration marks,” and “water flows through.”

Grammatical Range and Accuracy: Band 4.5

You attempt to describe a sequence using both simple statements and longer clauses, including a conditional construction in “if water will be more than constant level.” However, sentence structures are limited, and errors in verb forms, agreement, articles, and sentence construction occur frequently. Examples include “The diagram illustrate,” “two bottles are hold,” and “This is how water clock build and work.” The conditional sentence is also not formed accurately, making the relationship between the water level and overflow harder to follow. Some punctuation and spacing problems further interrupt the flow. Practise accurate present-simple passive forms for processes, such as “the bottle is attached,” and build longer sentences around one clear action at a time.
