Activity 1.1: Question the Answer
1Come up with a curious, creative, and fun question that could lead to the answer: 'Just add some milk.'Show solution
This is an open-ended creative activity. There is no single correct question. The idea is to think imaginatively about situations where this answer would make sense.
Some possible questions:
(i) 'My porridge has become too thick and lumpy — what should I do?'
(ii) 'How can I make this cup of tea less bitter and more creamy?'
(iii) 'The mashed potatoes are too dry and stiff — how do I fix them?'
(iv) 'My little sister refuses to drink her Horlicks because it tastes too strong — what can I do?'
Note: Any creative, thoughtful question that logically leads to the answer 'Just add some milk' is perfectly acceptable. The purpose of this activity is to practise thinking like a scientist — by asking good questions rather than only finding answers.

2Come up with a curious, creative, and fun question that could lead to the answer: 'Because the cat's teeth were crooked.'Show solution
This is an open-ended creative activity. There is no single correct question. Think of funny, imaginative, or even absurd situations where this answer would fit.
Some possible questions:
(i) 'Why did the cat's bite leave such a strange zigzag mark on the butter?'
(ii) 'Why did the dentist open a clinic especially for cats in our neighbourhood?'
(iii) 'Why did the cat keep dropping the fish it caught from the pond?'
(iv) 'Why did the vet say the cat needed braces?'
Note: Any imaginative question that logically or humorously leads to the answer 'Because the cat's teeth were crooked' is perfectly valid. The goal is to practise creative and scientific thinking.
