The diagram illustrate the process of build and oprate a homemade water clock.

Three are seven stages of the own water clock construct. In the first stage is tap on and after cover with hole finger. In the next top bottle fill to overflow and than fouth stage check the level constant of water beacuase it helps us to drain water or not.

in the bottem stage, check finger it is away from the hole after that check levels of minute water fill lower container. Finally once the water is fill last the whole process can repeat.

Overall, the process describe the seven stage of buld own water tank. Every stage is play imporatant role if any one missed water clock ia not able to build.

Task Achievement / Task Response: Band 4.5

You identify the subject as a homemade water clock and mention several relevant stages, including turning on the tap, filling the upper bottle to overflow, releasing the hole, and repeating the process. However, the account is incomplete and some steps are unclear or inaccurate: “check the level constant” does not explain that the water level is kept constant by the overflow, and “check levels of minute water fill lower container” does not clearly describe marking the lower bottle to show levels per minute. The construction details, such as the stand, straw, glue, tape, and lower bottle with its neck removed, are omitted. The overview mostly repeats that there are seven stages rather than summarising how the apparatus works. The response is also 24 words below the required minimum, limiting the detail provided.

Coherence and Cohesion: Band 5.5

The response follows the general order of the process, using phrases such as “In the first stage,” “In the next,” and “Finally,” so the reader can recognise a sequence. The short paragraphs also separate the process from a concluding overview. However, progression is not consistently clear because several stages are compressed into long, awkward sentences, and references such as “the bottem stage” and “after that check levels” do not make the sequence precise. The final paragraph repeats the idea that there are seven stages without adding a clear summary. Use one sentence for each main phase and connect them with accurate sequencing language, while making sure each reference identifies the relevant bottle or water level.

Lexical Resource: Band 5.0

You use some task-related vocabulary, including “tap,” “overflow,” “hole,” “finger,” and “lower container,” which helps establish the topic. However, the range is limited and several word choices or forms make the process difficult to understand: “water clock construct,” “check the level constant,” and “levels of minute water fill lower container” are not natural or precise descriptions. Spelling errors such as “oprate,” “bottem,” “beacuase,” and “imporatant” are also noticeable. Aim for accurate process vocabulary and common collocations, for example “attach the bottle to a stand,” “maintain a constant water level,” and “mark the water level at one-minute intervals.”

Grammatical Range and Accuracy: Band 4.5

The response attempts to describe a sequence using both simple statements and longer clauses, but grammatical errors are frequent and sometimes obscure the intended meaning. For example, “The diagram illustrate” has subject–verb disagreement, while “Three are seven stages” and “In the first stage is tap on” have faulty sentence structures. Verb forms and articles are also often missing or incorrect, as in “the water is fill” and “the process describe.” Capitalisation and punctuation are inconsistent, particularly where a new sentence begins with lowercase “in.” Build accurate simple sentences first, such as “First, turn on the tap and cover the hole with a finger,” then add a few correctly formed clauses to show how the stages relate.
