IELTS Writing Task 1 question

The diagram below shows the process for making a water clock.

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

HOW TO BUILD YOUR OWN WATER CLOCK

Student answer (Band 5.5)

The provided process chard illustrate information about the steps required to make our own water clock.

Overall, the stand contain a bottle and with hole and a small pipe attached to it and a beaker at the bottom stand which collects the water droplets felling from bottle and show time and we need to empty it for using it again.

Turning to the process, first we require a l-shape stand, a transparent bottle, a beaker, straw, glue, a tap and tape.

First we attach the bottle to the top of stand using a better water resistant tape and hole the bottle from center of its bottom and from it top and paste a straw to top hole by using glue. Now we paste marked container to bottom of stand which is marked according to calculate time. The beaker is made up of water bottle whose neck is cut off. now when we place the project under the tap we keep the finger placed over hole till the bottle fill up to where we attached the straw after removing the finger the droplets start collecting into beaker and show its level per minute.

Task Achievement / Task Response: Band 6.0

You cover the main purpose and several key stages: the upper bottle is fixed to a stand, water is allowed to fill to the straw, and the lower container collects the dripping water so its level can indicate time. The overview also recognises that the clock can be reused. However, some details are unclear or inaccurate: the diagram shows a hole at the base of the upper bottle, not a hole at its top, and the straw is attached near the top as an overflow drain. The numbered sequence—turning on the tap, covering the hole, filling to overflow, then removing the finger—is not presented clearly in order. Explain the calibration and final empty-and-repeat stage more precisely to make the account more complete.

Coherence and Cohesion: Band 6.0

The response has a recognisable overall structure, moving from an introduction and overview to a description of the materials and process. Sequencing words such as “first,” “now,” and “after removing the finger” help the reader follow the general procedure. However, the stages are not consistently separated or ordered: the paragraph shifts from assembling the apparatus to operating it, and the long final sentence combines several actions and outcomes. Some references are also difficult to follow, particularly “it” in the description of making holes and attaching the straw. Use distinct paragraphs for construction and operation, and connect each numbered stage with clear, consistent sequencing.

Lexical Resource: Band 5.5

You use relevant vocabulary for describing the apparatus and process, including “stand,” “straw,” “glue,” “droplets,” and “collects.” This gives you an adequate range for the topic, and the reader can generally identify the objects involved. However, several choices or forms are inaccurate or imprecise, such as “process chard,” “pipe” for the straw, “beaker” for the cut-off bottle, and “show time” for indicating elapsed time. “Better water resistant tape” is also an awkward description not supported by the diagram. Aim for precise process vocabulary and check spelling and collocations; for example, describe the lower bottle as a container and say that its marked water level indicates time.

Grammatical Range and Accuracy: Band 5.0

You attempt both simple and more extended sentence forms, including a sequence linked by “till” and “after,” and the overall meaning is usually recoverable. However, errors in agreement, articles, verb forms, and sentence construction occur in several places. For example, “the stand contain” should be “the stand contains,” while “the bottle fill up” needs a passive form such as “the bottle is filled.” The opening sentence also has an unclear structure, and the final sentence runs several steps together without clear punctuation. Use consistent present simple or passive forms for process descriptions, and divide long sentences so each action has a clear subject and verb.
