Task Achievement / Task Response — Band 4.0

The student attempts to describe the process of making a water clock, covering some basic aspects such as the materials needed and general steps like turning on the tap and covering holes with fingers. However, the response falls short of fully and accurately reporting the visual data. Key stages from the diagram, such as using a straw as an overflow drain, marking calibration lines on the lower bottle, and specific numbered stages, are either missed or described so vaguely that the process is difficult to follow. Furthermore, the inclusion of irrelevant personal precautions (such as wearing a mask or lab coat and performing the experiment at school rather than at home) detracts from the academic tone required for Task 1. Ideas are limited and under-developed, aligning the response with Band 4.

Coherence and Cohesion — Band 4.0

The organisation of the text is weak. While the writer attempts to use some sequence markers such as 'Beginning with' and 'Subsequently', the overall progression lacks clarity. The text is presented in one continuous, poorly structured block rather than logical paragraphs, and punctuation is erratic. Referencing is frequently unclear, leaving the reader confused about which bottle or action is being referred to (e.g., 'Adjust the water level of second bottle with first one'). Cohesive devices are inadequate or misused, resulting in a response that lacks logical flow and arrangement, consistent with Band 4.

Lexical Resource — Band 4.0

The vocabulary used is very basic, repetitive, and restricted to simple terms related to the task (e.g., 'plastic bottles', 'straw', 'stand', 'tap', 'finger'). There are numerous spelling errors ('illustrate' instead of illustrates, 'consisits', 'Begning', 'Allign', 'beacuse', 'agaiN', 'glaps', 'horm', 'libraray') and word choice issues. The writer attempts some less common vocabulary related to lab safety, but these are misspelled and inappropriate for an academic report. The limited range of vocabulary and frequent errors that strain the reader place this criterion at Band 4.

Grammatical Range and Accuracy — Band 4.0

The grammatical range is extremely limited, relying heavily on simple imperative sentences and fragmented clauses. There is a lack of control over basic sentence structures, leading to numerous grammatical errors, missing prepositions, and incorrect verb forms (e.g., 'The diagram illustrate', 'with straw attached', 'away your finger', 'Some time it become danger'). Punctuation is faulty throughout, and capitalisation is misused. Errors are frequent and often distort the meaning of the sentences, making it difficult for the reader to follow the intended instructions. This performance corresponds to Band 4.
