Task Achievement / Task Response: Band 2.5

The response makes only a minimal attempt to describe the process. It mentions a tap and a plastic bottle, which are relevant, but does not explain how the bottles are arranged, how water flows through the apparatus, or any of the seven stages. The overview, “in the diagram on the top it has a tap and then a plastic bottle is used,” is too vague to identify the process’s main features or outcome. The opening also focuses on introducing the report rather than describing the diagram. The response is substantially below the required 150 words, leaving too little information to address the task. To improve, give a clear overview and describe the construction and sequence, including the overflow straw, the lower bottle, and the repeated timing procedure.

Coherence and Cohesion: Band 3.5

There is a basic attempt to organise the response: an introductory sentence is followed by a sentence beginning “Overall,” which signals an overview. However, the ideas do not progress into a description of the process, and the second sentence ends before completing its point. The opening phrase “through this information make a report” does not clearly connect the task to the information that follows. With only two sentences, there is no paragraph development or sequencing of stages, and the reader cannot follow how the clock is assembled or used. Use a short introduction, a distinct overview, and then a logically ordered account of the construction and operating stages, with clear links such as “first,” “next,” and “finally.”

Lexical Resource: Band 4.5

The response uses a few relevant basic terms, including “tap,” “plastic bottle,” and “diagram,” so the subject is partly identifiable. However, the vocabulary is too limited to describe the apparatus or its operation, and several choices or spellings reduce clarity: “water click” appears to be an inaccurate term for “water clock,” while “univerdity lecture” is misspelled and “map” is not an appropriate label for this visual. The phrase “it has a tap” is also imprecise for describing a process diagram. Build a small set of accurate process terms, such as “upper bottle,” “overflow straw,” “drip,” and “calibration marks,” and use verbs such as “attach,” “fill,” and “measure” to convey the stages precisely.

Grammatical Range and Accuracy: Band 4.5

The response attempts more than one sentence pattern, but control is weak in both sentences. In “The map under illustrate that how you make your own water click,” the subject and verb do not agree, and the clause structure after “illustrate” is not grammatical. The following phrase, “through this information make a report,” lacks a clear subject and finite verb. In the second sentence, “we can see that in the diagram on the top it has” combines clauses awkwardly, while “a tap and then a plastic bottle is used” does not form a clear, well-controlled description. Aim first for accurate simple sentences with a clear subject and verb, then add controlled sequencing clauses, for example, “Water flows from the upper bottle into the lower container.”
