Sample questions

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

01
Sort the materials by how well they conduct heat.
Sort into
- conducts heat well
- does not conduct heat
- copper
- wood
- aluminium
- plastic
Read the explanation
Metals conduct heat well; wood and plastic do not.
02
Sort the materials by whether they conduct electricity.
Sort into
- conducts electricity
- an insulator
- copper wire
- rubber
- iron
- glass
Read the explanation
Metals conduct electricity; rubber and glass are insulators.
03
Sort the materials into groups.
Sort into
- breaks down easily
- takes a very long time to break down
- fallen leaves
- a plastic bag
- food scraps
- a glass bottle
Read the explanation
Some materials break down naturally; others take a very long time.

Game teaching guide

What children will practise

Sorts materials by four properties: conducting heat, conducting electricity, breaking down, and absorbing water. Questions 1 and 2 match indicator ว 2.1 ป.4/1 (comparing hardness, elasticity, heat and electrical conduction), a Grade 4 topic; question 4 links to ว 2.1 ป.2/1 (absorbency).

What's in the worksheet

4 questions, a sorting game with four items each - Copper and aluminium conduct heat well; wood and plastic do not - Copper wire and iron conduct electricity; rubber and glass are insulators - Fallen leaves and food scraps break down easily; a plastic bag and a glass bottle do not - Cotton cloth and tissue paper absorb water; a plastic bag and a tyre are waterproof

How to use it in class

Use it after testing materials, such as dripping water on samples or standing different spoons in hot water, about 6 minutes in teams. After question 1, ask why pan handles are wood or plastic. Question 3 connects to the school's rubbish sorting. On question 2, stress safety: never experiment with mains electricity. You can link it to a class and record it in the gradebook. In English mode, the question 1 label does not conduct heat overstates it: wood and plastic conduct heat poorly, not at all, as the Thai label says.

Common sticking points

- Question 3: saying the glass bottle breaks down easily because glass shatters. Separate them: shattering is not decomposing. - Question 2: calling glass a conductor because it is hard and shiny like metal. Point to the porcelain or glass insulators on power poles. - Question 4: calling the tyre absorbent because tyres are wet after rain. Ask whether the water soaks in or just sits on the surface.
