Sample questions

A few real prompts from the game to help you choose an activity for your class.

01
What does a plant need to make food?
- light, water and carbon dioxide
- minerals in soil, fertiliser and oxygen
- water, minerals and darkness
Read the explanation
It needs light, water and carbon dioxide - all three - to make food.
02
What makes a circuit complete?
- just a bulb
- an unbroken loop
- broken anywhere
Read the explanation
It must form an unbroken loop for current to flow.
03
Boiling water is which change of state?
- solid to liquid
- gas to liquid
- liquid to gas
Read the explanation
Water goes from liquid to gas - that is evaporation, or vaporisation.

What children will practise

A mixed Grade 4 review: what plants use to make food, a complete circuit, boiling water, the producer in a food chain, how the Moon shines, and the lungs in the respiratory system. Tagged ว 1.2 ป.4/1 (the job of leaves) and touching ว 3.1 ป.4/2 (the Moon).

What's in the worksheet

6 questions, multiple choice with three options each - Plants make food with light, water and carbon dioxide - A complete circuit is an unbroken loop - Boiling water is liquid to gas - The producer is the plant; the Moon shines by reflecting sunlight

How to use it in class

A 5-minute review before Grade 4 end-of-term tests, played solo. Use the gradebook results to pick a topic set to replay, such as QS-SCI-P4-PLANT-01 or QS-SCI-P4-MOON-01. In question 1 the distractor minerals, fertiliser and oxygen reflects a real misconception, so stop and explain. After question 5, ask why the Moon looks so bright when it has no light of its own. You can link it to a class and record it in the gradebook.

Common sticking points

- Question 1: choosing minerals, fertiliser and oxygen, believing plants eat soil and fertiliser. Separate them: fertiliser helps growth, but food is made in the leaf. - Question 5: choosing it makes its own light because the Moon looks so bright. Demonstrate with a ball and a torch. - Question 3: choosing gas to liquid, having seen drops on the pot lid. Ask what the water in the pot is turning into. - Question 3: the in-game explanation calls boiling evaporation, which is loose. Evaporation happens at the surface at any temperature, boiling throughout the liquid at the boiling point, though both turn liquid into gas. Separate them for the class.
