HOW TO BUILD YOUR OWN WATER CLOCK

Student answer (Band 5.5)

The diagram depicts the process that how to build our own water clock.

Overall, it is clearly seen that this diagram consists of seven various steps. These steps start from tap on and end at empty and repeat process for timing things. Several major steps are include in this process diagram such as cover hole with our finger and make the level constant.

Initially, we bound the bottle with stand with the assist of tape. We aslo attach the straw at the top of the bottle through the glue. Then, we tap on the null and after that we cover the hole with our any finger that is located on the bottom of plastic bottle. Afterwards, we fill the bottle with water till the level of the straw.

Moreover, when the water filled in bottle till the straw then we pull back our finger on the hole. Subsequently, we analyze the speed of water per minute that drops on the another cut of plastic bottle. Thereafter, we will empty the bottom bottle and we perform this process again. In this way, we create our own water clock.

Task Achievement / Task Response: Band 6.0

You cover the main sequence and provide an overview that identifies seven stages, from turning on the tap to emptying and repeating the process. Several details are also relevant, including attaching the upper bottle to a stand, using a straw, releasing the hole, and collecting water in the lower bottle. However, some stages are unclear or imprecise: “tap on the null” does not identify the tap clearly, and “analyze the speed of water per minute” does not explain that the lower bottle is marked to show the water level over time. The description also says the straw is attached “at the top,” rather than clarifying its overflow function. Develop these key features more precisely to make the process fully clear.

Coherence and Cohesion: Band 6.0

The response has a coherent overall arrangement: an introduction and overview are followed by the construction and operating stages in broadly chronological order. Sequencing expressions such as “Initially,” “Then,” “Afterwards,” and “Subsequently” help the reader follow the process. However, the progression is occasionally mechanical, and some links do not make the relationship between steps clear. For example, “Moreover” introduces the release of the finger, which is a continuation rather than an additional point, while “when the water filled in bottle till the straw” repeats the previous filling information. Paragraphing is present but could better separate the overview from the detailed stages. Use fewer, more precise transitions and ensure each sentence adds a distinct step.

Lexical Resource: Band 5.0

You use enough process-related vocabulary to communicate the general procedure, including “attach,” “straw,” “hole,” “drops,” and “repeat.” There are also attempts at more specific wording, such as “level constant” and “speed of water per minute.” However, several word choices and collocations are noticeably inaccurate or unnatural, which makes some details harder to understand. “Tap on the null” is unclear, “bound the bottle with stand” is not the natural expression for fixing it in place, and “another cut of plastic bottle” does not clearly name the lower container. Spelling errors such as “aslo” also reduce accuracy. Build a more precise set of terms for the apparatus and use natural process collocations consistently.

Grammatical Range and Accuracy: Band 5.0

You attempt both simple and more complex sentence forms, including a time clause beginning “when” and sequencing clauses with “after that” and “thereafter.” The overall meaning is usually recoverable, but errors in verb forms, articles, agreement, and sentence construction are noticeable. For example, “Several major steps are include” combines incompatible verb forms, while “when the water filled in bottle” needs a more accurate tense and article pattern. “We fill the bottle” also shifts into the present tense after past-tense narration, and “we perform this process again” continues that inconsistency. Practise describing processes consistently in the present simple, and check article use and verb forms when combining clauses.
