Sort into
- holds water well
- water drains straight through
- clay
- sandy soil

Game teaching guide

What children will practise

Tells soil from rock, sorts soils by how they hold water, separates resources that run out from those that renew, and natural from built water sources. Matches ว 3.2 ป.2/1 (soil make-up and kinds of soil) and ป.2/2 (uses of soil).

What's in the worksheet

4 questions, a sorting game with four items each - Loam and clay are soil; granite and limestone are rock - Clay and loam hold water well; sandy soil and gravel let water drain straight through - Oil and coal run out; sunlight and wind renew themselves - Rivers and the sea are natural; a dam and an irrigation canal are built by people

How to use it in class

Play it after children have handled three soils and poured water through them in cut bottles, about 6 minutes in teams. In question 2, recall the real results before tapping. Questions 3 and 4 move a little beyond soil, so use them as a bridge to natural resources, for instance by asking the name of the nearest dam. You can link it to a class and record it in the gradebook.

Common sticking points

- Question 1: calling clay a rock, having seen dried clay set hard. Let children feel wet clay next to a real rock. - Question 2: hesitating over loam, which holds water only moderately. Explain that compared with sand and gravel, loam holds water well. - Question 3: calling oil renewable because the petrol station never runs out. Explain that oil takes so long to form that it counts as running out. - Question 2: the prompt says sort the soils, but gravel is not a soil. If a child points this out, praise them, and explain that gravel is there to compare how fast water drains through.
