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 6.0)

The diagram shows the procedure of how to build a water clock all by yourself.

Overall, the process has 7 defferent steps. Moreover, we will need some additional items to make the clock, items like a stand, tape, straw, tap water, two water bottle and a pen for marking.

Starting from the scratch, it first require to make a hole in bottom and on the neck part of the bottle before attaching it to the stand with a tape. Secondly, cut the other bottle in half, using the bottom part as a container, putting it on the surface of the stand. Attach a straw to the neck hole with the help of a glue for better air flow. Cover the bottom hole with a finger untill the bottle overflows from the straw. After staying the reach the water to a constant level, move the finger away from that hole.

It then, starts dropping down the water in a constant speed. Mark the levels per minute on the container. The clock is ready now, we can empty the bottom part and repeat the process for timing things.

Task Achievement / Task Response: Band 6.5

You cover the main purpose and sequence, including the seven stages, the overflow straw, the constant water level, marking levels per minute, and repeating the process. The overview also identifies the materials and the overall number of steps. This gives the report a clear, relevant account of the diagram. However, some construction details are inaccurate or unclear: the diagram shows a hole at the base of the upper bottle, not a hole in its neck, and the straw is fixed near the top as an overflow drain rather than attached to the neck hole for airflow. The account of preparing and attaching the bottles is also less precise than the later operating stages. More exact description of the apparatus would strengthen coverage.

Coherence and Cohesion: Band 6.5

The report has a recognisable structure: an introduction, an overview, construction details, and then the clock’s operation. Sequencing expressions such as “Starting from the scratch,” “Secondly,” and “It then” help the reader follow the process, and the final sentence gives a clear ending. The progression is generally logical, but some links are mechanical or awkward, particularly “After staying the reach the water to a constant level,” which makes the transition between filling and releasing the water difficult to follow. The construction steps are also compressed into one paragraph, while the operating stages are separated. Use clearer stage-to-stage links and divide the description into more balanced paragraphs to make the progression smoother.

Lexical Resource: Band 5.5

You use relevant process vocabulary, including “attach,” “container,” “overflows,” “constant speed,” and “levels per minute,” so the reader can understand the basic procedure. There is some variety in how you describe the stages, but several word-choice, collocation, and spelling problems reduce precision. For example, “two water bottle” is inaccurate in form, “better air flow” does not describe the straw’s overflow function, and “starts dropping down the water” is an unnatural phrase. “Defferent” and “untill” are also misspelled. Aim for precise technical wording and check spelling; terms such as “upper bottle,” “overflow straw,” and “water drips” would describe the diagram more naturally.

Grammatical Range and Accuracy: Band 5.0

You attempt a mixture of simple sentences and longer structures, including sequencing clauses and instructions, and the main meaning is usually recoverable. However, errors occur often enough to make some sentences difficult to process. Examples include “it first require,” where the verb does not agree with its subject, and “After staying the reach the water to a constant level,” which has a faulty clause structure. The sentence beginning “Starting from the scratch, it first require” also has an unclear subject, and “It then, starts” uses punctuation incorrectly. Practise forming clear passive process descriptions and checking subject–verb agreement, articles, and clause structure. More accurate sentence construction would make the sequence easier to follow.
