PSLE Situational Writing 3: The Science Fair

Practice problems · 3 questions · Primary school · Updated 21 Sept 2026

A formal email to a teacher, asking for something. That makes the tone matter as much as the facts.

The situation​

Rachel and her brother read a notice in the newspaper over breakfast. The fair falls on a Friday, which is when Rachel has Science Club.

A cartoon of two primary school pupils reading a newspaper notice about a young scientists fair, beside the notice itself.

Visual source: the notice holds the facts. The pupils point out the problem you have to solve.

Text version of the notice

Young Scientists Fair

Open to every primary school in Singapore.

  • Friday 15 August, 3 p.m. to 6 p.m.
  • Science Centre, Hall B
  • Free entry for pupils with a school letter
  • Pupils may enter one project each
  • Closing date for entries: Monday 28 July

Every entrant must be accompanied by a teacher or parent. Projects must fit on one table.

The two pupils are saying:

  • "The fair is on a Friday afternoon. That is when you have Science Club."
  • "Then you will have to ask Mrs Lim to excuse you."

Your task​

Imagine you are Rachel. Write an email to Mrs Lim, the teacher in charge of the Science Club, asking to be excused from Science Club on Friday 15 August so that you can enter the fair.

Your email must include:

  • what the fair is, and when and where it is held
  • why you want to go
  • what you are asking Mrs Lim for
  • what you will do about the Science Club work you miss
  • that every entrant must be accompanied by a teacher or parent
  • a polite close that asks for her reply

Check your plan​

Mrs Lim is your teacher. Which opening and sign-off pair is right?

Show answer & explanation

Answer: (B) Dear Mrs Lim, … Yours sincerely, Rachel

The correct answer is (B). You know this teacher’s name, so you open "Dear Mrs Lim" and close "Yours sincerely". (A) is too casual for a request to a teacher. (C) pairs "Yours faithfully" with "Dear Sir or Madam", which is what you use when you do not know the name, and you do know hers. (D) is not a greeting at all, and "Regards" is for a note between colleagues.


You are asking to miss a session. Which sentence makes the request easiest to say yes to?

Show answer & explanation

Answer: (B) I will ask a friend what happened at Science Club, and I will catch up on the work before the next session.

The correct answer is (B). It shows you have thought about the cost to the club, not only about what you want. (A) argues that her session matters less, which is rude. (C) announces instead of asking. (D) is pressure rather than a reason, and it contradicts the situation: the clash is yours, not the whole class’s. The task asks what you will do about the work you miss, so (B) is also one of the things you were asked for.

Write your email​

✍️ Your turn

Write Rachel's email to Mrs Lim. Cover all six points in the list above. Stay polite throughout, and take the date, the time and the place straight from the notice.

The model​

Open the model email

To: [email protected] Subject: Request to be excused from Science Club on 15 August

Dear Mrs Lim,

I am writing to ask whether I may be excused from Science Club on Friday 15 August.

There is a Young Scientists Fair that afternoon, from 3 p.m. to 6 p.m., at the Science Centre in Hall B. It is open to every primary school in Singapore, and each pupil may enter one project. I have been working on a project about how quickly different soils drain, and I would like to enter it. Entries close on Monday 28 July, so I need to decide soon.

The notice also says that every entrant must be accompanied by a teacher or parent. My mother has said she can bring me, so the club would not need to send anyone.

I know that missing a session is not ideal. If you allow it, I will find out from a friend what the club covered, and I will finish the work before the following session.

I would be grateful if you could let me know whether this is all right. Thank you for considering my request.

Yours sincerely, Rachel Primary 6 Resilience

Why this scores​

What the model doesWhy it works
"I am writing to ask whether I may be excused"The purpose is clear in the first line
Gives the date, time and hall from the noticeThe facts are taken exactly as printed
Says why the fair matters to her, with a real projectA reason about her own project
Settles the accompanying adult before being askedRemoves the objection Mrs Lim would raise first
Offers to catch up on the club workMakes a yes easier to give
Asks for a reply and thanks herA polite close that still asks for something

Notice what the model does not do. It never argues that the fair matters more than Science Club, and it never assumes the answer is yes.
