Original practice questions with worked answers
Attempt each question before expanding its answer. These examples were written for this page; they are not extracts from a downloadable booklet or an official assessment paper.
1. States of matter
Question: Name the state of water in an ice cube, a glass of water and water vapour.
Show answer and explanation
Ice is solid, liquid water is liquid, and water vapour is gas. A change of state changes the physical form of the water; it does not make the water become a different substance.
2. Separating a mixture
Question: How can a mixture of dry beans and small stones be separated safely for a classroom demonstration?
Show answer and explanation
The larger visible pieces can be separated by careful hand picking under teacher guidance. Explain which visible difference is used. Materials handled during a demonstration should not automatically be treated as ready-to-eat food.
3. Safe observation
Question: A learner finds an unknown liquid in the classroom. Should the learner taste it to identify it? Explain.
Show answer and explanation
No. Do not taste or closely smell an unknown substance. Leave it alone and tell the teacher. A good answer identifies the unsafe action and gives a safe next step.
How to review your Science and Technology answers
- Read the instruction. Identify whether you need to name, explain, compare, calculate or give an example. Answer the task that was actually set.
- Make your reasoning visible. Show working for a calculation or give the detail that supports a written answer. A correct result without understanding is difficult to apply to a new question.
- Correct one difficulty. Record the error and explain the change needed. Try a similar example later without copying the worked answer.
Teachers and parents can use a short set to start a discussion, identify a misunderstanding and select a follow-up task. These activities provide focused practice; they do not certify coverage of every curriculum outcome or replace classroom teaching.
