HOW TO BUILD YOUR OWN WATER CLOCK

Student answer (Band 6.0)

The process diagram illustrates a way of making water clock in seven steps.

overall,we need two bottles connected to the stand. In the beginning we need to fill the first plastic bootle from the tap and in the end we need to empty the second plastic bottle and repeat the process for fixting the timing thing.

To begin with,we need a stand and with the help of tape we have to attach a bottle in the upper part of the stand.Then we have to turn on the tap and fill water until it start overflowing.In the upper corner at the water level of the jar,we will attach a straw so that extra water can go away. After that we have make a hole under the bottle and cover it with finger.

Moreover,we need to set up another bottle under the first one. Then we need to leave the hole from first bottle free so that the water from upper portion can flow to the second bottle.In the next process,we have to check the level of water coming in every minute. After the tranferring process is finisher we need to empty the bottles and repeat the whole process to examine the timing.

Task Achievement / Task Response: Band 6.0

The report identifies the diagram as a seven-step process and includes several key features, such as attaching the upper bottle to a stand, using a straw for overflow, allowing water to pass into a lower bottle, and repeating the process. The opening overview also captures the broad arrangement and the final action. However, some stages are reported in the wrong order: the hole should be covered before the upper bottle is filled, and the water level is kept constant before the finger is removed. The account also says to empty both bottles, whereas the instructions specify emptying and repeating the process. Clarifying the calibration marks on the lower bottle and explaining that they show levels per minute would make the description more complete and precise.

Coherence and Cohesion: Band 6.0

The response has a recognisable overall structure: an introduction and overview are followed by a sequence of procedural details. Connectors such as “To begin with,” “After that,” and “Moreover” help signal progression, and the main stages can generally be followed. However, the sequence is not consistently logical, particularly where filling and covering the hole are placed in a different order from the diagram. “Moreover” does not clearly express the relationship between setting up the lower bottle and the preceding steps, while “In the next process” is vague. The overview and body also repeat the instruction to empty and repeat. Grouping the setup first, then the water-flow stages, and finally the timing and reset would create clearer progression and referencing.

Lexical Resource: Band 5.5

The response uses enough process vocabulary to communicate the main actions, including “attach,” “overflowing,” “straw,” “flow,” and “level.” It also attempts more specific wording, such as “upper portion” and “transferring process.” However, several spelling and word-choice errors reduce precision: “bootle,” “fixting,” “tranfering,” and “finisher” appear in place of the intended forms, and “timing thing” is too informal and imprecise for a report. Some phrases are also unnatural, such as “leave the hole … free” and “check the level of water coming in every minute.” Use accurate process terms and collocations, for example “uncover the hole,” “mark the water level,” and “measure time.”

Grammatical Range and Accuracy: Band 5.5

There is a mix of simple and more complex sentence forms, including clauses with “so that” and “until,” and the meaning is generally understandable. Some grammatical errors remain, particularly with articles, verb forms, and sentence construction. For example, “making water clock” needs an article, “until it start overflowing” has incorrect subject–verb agreement, and “After that we have make a hole” uses an incorrect verb form. The sentence beginning “overall,we need” also needs appropriate capitalisation and punctuation, while several sentences would benefit from commas after introductory phrases. Aim to use consistent present simple forms for the process and check articles and agreement when revising.
