Find the flaw
A student's report on enzyme activity contains four errors. For each error below, identify which report section it appears in, describe the error, and write a corrected version.
| Student's writing | Report section | What is wrong? | Corrected version |
|---|---|---|---|
| "The results were good because the enzyme worked better at higher temperatures." | |||
| "We found that the experiment was successful." | |||
| "Add a bit of solution to the test tube." | |||
| The Discussion section is a word-for-word copy of the Results section. |
Write a structured conclusion
Scenario
Investigation aim: "Does temperature affect the dissolving time of salt in water?"
Hypothesis: "As temperature increases, dissolving time will decrease."
Results: 20 °C → 85 s | 40 °C → 41 s | 60 °C → 17 s
(a) Restate the aim and answer it directly. (Use past tense, no "I/we" language.)
(b) Reference at least two specific data values from the results to support the conclusion.
(c) Identify one source of error in this investigation and suggest one improvement.
1. Rewrite this sentence in correct scientific style: "I heated the solution because I thought it would work better."
2. A student's conclusion says "the experiment proves that temperature always makes things dissolve faster." Identify two problems with this statement.
