Write a report for a university lecturer describing the information below.

HOW TO BUILD YOUR OWN WATER CLOCK

Student answer (Band 4.5)

First step in building in water clock is to take strand,a tape,plastic bottle,straw,pencil for scaling and glue.now you have equipments which are going to be used in makind such a wonderfull model.now we going toward our fist step in making this wonderfull piece of model first take a water bottle and cut it into halves and then tapped upper half with bottle neck to verticle pipe of your strand and place other half bottle on the board of strand and our second step is going to insert straw in half of necked bottle . third step is cover upper half of bottle with card bord and then punch hole in it .our fourth step is to scale bottle part which was placed ob stran d with pencil that you have taken and mange equal spacing between all lines . now our water clock model has been prepared . lets experiment the model which we have prepared . open tap and let check it that it is working or not.

Task Achievement / Task Response: Band 4.5

The response recognises that the task concerns constructing and testing a water clock, and it includes several relevant components, such as bottles, a stand, a straw, and calibration marks. However, important stages are misreported or invented: the diagram shows the upper bottle attached to a stand, a straw glued near its top as an overflow drain, and water dripping through a hole into the lower bottle. Instead, you describe cutting a bottle in half, attaching the upper half “with bottle neck,” covering it with cardboard, and punching a hole in that cover. The numbered operating sequence—covering the hole, filling the upper bottle to overflow, marking levels, and repeating for timing—is not accurately explained. A clearer account of the actual construction and stages, with a concise overview, would make the report more complete and relevant.

Coherence and Cohesion: Band 4.5

There is a basic chronological intention: you introduce materials, describe construction, and then move to testing with “now our water clock model has been prepared.” This gives the reader a broad sense of progression. However, the report is presented as one long paragraph, and the sequence is difficult to follow because steps are inconsistently numbered: “our second step” is followed by “third step” and “our fourth step,” while the first construction action is not clearly separated. Connectors such as “now,” “and then,” and “our” are repeated, and some references, including “other half bottle” and “bottle part,” are unclear. Use separate paragraphs for the apparatus and operation, and organise the stages with precise sequencing and clear references.

Lexical Resource: Band 4.5

You use some task-related vocabulary, including “straw,” “glue,” “pencil,” “scale,” and “tap,” so the reader can identify the general subject. However, the range is basic and several choices are inaccurate or unclear for describing the diagram. “Strand” appears to mean “stand,” “necked bottle” is not a clear description of the lower container, and “wonderfull piece of model” is informal and repetitive. Spelling errors such as “makind,” “verticle,” “bord,” and “mange” also make the description harder to read. Aim for precise process vocabulary and standard spelling—for example, describe the bottle as “secured to a stand,” the straw as an “overflow outlet,” and the marks as “calibration lines.”

Grammatical Range and Accuracy: Band 4.5

The response attempts to connect actions using longer sentences, for example, “first take a water bottle and cut it into halves and then…” This shows an effort to describe a sequence, but sentence structures are mostly simple or joined by repeated “and,” and frequent grammatical errors sometimes obscure the intended relationships. Examples include missing articles and subjects in “First step in building in water clock,” “now we going toward,” and “open tap,” as well as faulty verb forms in “then tapped upper half” and “let check it.” Agreement and prepositions are also unreliable, as in “which was placed ob strand.” Use complete sentences with consistent imperative forms for instructions, or passive forms for a report, and check articles, verb forms, and sentence boundaries.
