The process diagram illustrates how u can manufactured your water clock .

Overall,the process pass by seven stages , the first stage is the important to began this building also both satge 2 and 5 be an imporant stages to get the final water clock , While this process contained some matriel such as plastic bottle,tape and stand, straw .

The first stage is tap on,then cover the hole of the plastic bottle with fingers of your hands where the bottle fils with the water, let it fill to the top , after that the water become in constant level , using the glue and straw there, while pushing fingers away from the hole , the water will falls in the next plastic water (neck cut off), by levels in differents minutes , in the end of the process the plastic bottle will be empty , so u can repeat the process again and again .

Task Achievement / Task Response: Band 5.5

You identify the diagram as a seven-stage process and mention several relevant components, including the tap, bottle, straw, glue and stand. You also describe the water overflowing and the final instruction to repeat the process. However, some important details are unclear or inaccurately presented: the upper bottle is filled until water overflows, and the lower bottle is used to collect the dripping water and is marked with levels; these functions are not explained clearly. The overview that stages 1, 2 and 5 are especially important is not supported by the diagram, and the sequence is muddled when materials and actions are combined. To develop the report further, give a clear overview of how the apparatus works, then describe the construction and stages in order.

Coherence and Cohesion: Band 6.0

The response has a recognisable overall structure: an opening overview is followed by a description of the stages, and sequencing expressions such as “then,” “after that” and “in the end” help show progression. This gives the reader a basic route through the process. However, the overview sentence is crowded with several ideas, and the main paragraph combines construction details, water movement and stage instructions without clear grouping. For example, “using the glue and straw there” interrupts the account of the water flow, while “by levels in differents minutes” does not clearly connect to the calibration marks. Organise the report into clearer stages or groups, and use references such as “the upper bottle” and “the lower container” consistently to make relationships easier to follow.

Lexical Resource: Band 5.0

You use some task-related vocabulary, including “plastic bottle,” “straw,” “glue,” “constant level” and “repeat the process,” so the reader can recognise the subject. However, the range is limited and several word choices or forms make the description difficult to interpret. “The process pass by seven stages” is not a natural way to describe a sequence, and “the water will falls” and “levels in differents minutes” are unclear expressions. There are also noticeable spelling errors, such as “imporant,” “matriel” and “satge.” Aim for precise process vocabulary and check spelling and word forms; for instance, describe water as “dripping into the lower bottle” and the marks as “calibration lines.”

Grammatical Range and Accuracy: Band 5.0

You attempt both simple statements and longer sentences with sequencing clauses, as in “after that the water become in constant level.” This shows an effort to connect stages, but the range is limited and errors occur frequently enough to make some relationships unclear. Examples include “how u can manufactured,” “the process pass,” “the bottle fils,” and “the water will falls,” which show problems with verb forms and agreement. Articles and sentence boundaries also need attention: “the first stage is the important” and the long final sentence would be clearer if divided into shorter sentences. Practise accurate present-simple passive forms for processes, such as “The bottle is filled,” and check subject–verb agreement and punctuation when joining steps.
