HOW TO BUILD YOUR OWN WATER CLOCK

Student answer (Band 4.5)

The picture describes the water clock processing method.

Overall, totall seven stages take place in the whole process.First of all,the materials required to make the water clock is collected.A suitable container is made to hold the water.A small hole is than made to allow water to flow out gradually. After that,water is pour into container as the water slowly flows through the gole the level of water inside the cobtainer begin decreasing.

Then straw is used to keep the level of water constan,furthermore fingers are keep away from the hole of container.The measurements and marking

Task Achievement / Task Response: Band 4.0

The response identifies the topic and signals that the process has seven stages, but it describes the diagram only minimally. It mentions collecting materials, making a hole, adding water and marking measurements, yet several key stages and components are missing or unclear: the tap, the upper and lower bottles, the overflow straw, the constant water level, and the final emptying and repetition for timing. The statement that the straw keeps the water level constant misrepresents its role; it drains excess water to maintain a constant level in the upper bottle. The report also stops mid-sentence at “The measurements and marking”. It is 55 words below the required minimum, which contributes to the limited coverage. Develop a complete, accurate account of the setup and sequence.

Coherence and Cohesion: Band 4.5

There is a basic attempt to organise the process in sequence, using “Overall”, “First of all” and “After that”. This gives the reader some sense of progression, and the response begins with a general statement before describing stages. However, the sequence is not carried through to a clear ending, and the final phrase, “The measurements and marking”, is incomplete. Several ideas are crowded into one paragraph, while transitions such as “furthermore” do not clearly show the relationship between the steps. Punctuation spacing is also inconsistent, making the text harder to follow. Use separate overview and process paragraphs, connect each stage in order, and finish with the clock’s repeated use for timing.

Lexical Resource: Band 5.0

The response uses some relevant process vocabulary, including “container”, “hole”, “flow”, “straw” and “measurements”, so the basic subject is recognisable. However, the range is limited and some word choices are inaccurate or unclear. “Water clock processing method” is an awkward description of the diagram, and “the gole” and “cobtainer” appear to be spelling errors that interrupt reading. “The measurements and marking” does not express a complete idea. Choose precise terms for the apparatus and its function, such as “upper bottle”, “overflow straw”, “calibration marks” and “lower container”. Check spelling carefully and use process verbs such as “attach”, “drain” and “mark” to describe the stages more clearly.

Grammatical Range and Accuracy: Band 4.5

The response attempts both simple and linked sentences, for example, “After that, water is pour into container as the water slowly flows…”. However, errors are frequent and sometimes make the process difficult to understand. Verb forms and agreement are often incorrect: “materials … is collected”, “water is pour”, and “fingers are keep away” should use appropriate passive forms. Articles are missing in “into container”, and the sentence beginning “After that” runs several stages together without clear punctuation. The final fragment, “The measurements and marking”, is not a complete sentence. Practise accurate passive constructions for process descriptions, and check subject–verb agreement, articles and sentence boundaries before finishing.
