Task Achievement / Task Response: Band 4.0

The response identifies that the diagram has seven stages and mentions several materials, so it shows some awareness of the task. However, the process is only minimally described and important details are missing or inaccurate: the straw is an overflow drain, not the hole from which water is released, and the water drips through a hole at the base of the upper bottle into the lower one. The account also does not clearly explain how the apparatus is assembled or how the lower bottle is marked to measure levels per minute. The overview is vague, and the final claim about repeating the process “to create” the clock is misleading. The response is also 13 words below the required minimum, limiting its development.

Coherence and Cohesion: Band 5.0

There is a basic attempt to organise the report: an opening statement is followed by a summary of the stages, and sequencing words such as “then,” “after this” and “after completing” help show order. However, the response has only two paragraphs, with the process compressed into one long, difficult-to-follow sentence. The stages are not clearly separated, and the sequence becomes confusing when the writer moves from filling the bottle to maintaining a constant level and then refers to water coming through the straw. Repetition of “then” and “process” also makes the progression mechanical. Use separate sentences for the construction and operation, and connect each stage with precise sequencing language.

Lexical Resource: Band 5.0

The response uses some relevant task vocabulary, including “plastic bottle,” “straw,” “tap,” “overflow” and “level,” which helps identify the subject. However, the range is limited and several word choices or collocations are inaccurate, sometimes making the process unclear. For example, “water making in clock” does not naturally describe the task, and “water coming in the straw” misidentifies the route of the water. “Create water clock” is repeated even though the clock is already assembled before it is used. Spelling errors such as “intiate,” “untill,” “mantain” and “deffects” are noticeable. Aim for precise process vocabulary, such as “assemble,” “drip,” “calibrate” and “measure,” and check spelling carefully.

Grammatical Range and Accuracy: Band 5.0

The response attempts a few longer structures, including “Wait until the bottle is filled to overflow and maintain the level of water,” but control is uneven. The opening has a subject–verb agreement error in “This diagram illustrate,” and articles and sentence structure are problematic in phrases such as “process of water making in clock.” The long sentence beginning “Wait” joins several stages without clear grammatical boundaries, and the shift between instructions and description makes the sequence harder to follow. Capitalisation is also inconsistent, as in “We” after a comma. Use complete sentences with a consistent present simple or passive form, for example, “Water is allowed to fill the upper bottle until it overflows.” Punctuate each stage separately.
