Game teaching guide

What children will practise

Sorts things by four observable effects: attracted by a magnet or not, floats or sinks, loud or quiet sound, natural or man-made light. Its lead topic matches indicator ว 2.2 ป.3/3 (sorting objects by magnetic attraction), a Grade 3 topic; question 4 on light sources links to ว 2.3 ป.2/1.

What's in the worksheet

4 questions, a sorting game with four items each - A nail and a steel paper clip are attracted by a magnet; paper and an eraser are not - Wood and foam float; a rock and a coin sink - A whisper and rustling leaves are quiet; an aeroplane and a thunderclap are loud - The Sun and lightning are natural light; a light bulb and a torch are made by people

How to use it in class

Best after a carousel of hands-on stations (magnets, a water tub, listening), about 6 minutes in teams. Before each reveal, ask teams which items they actually tried. After question 2, if you have a tub, drop in a coin and a piece of foam. On question 1, mention that magnets do not attract every metal. You can link it to a class and record it in the gradebook. The in-game explanation for question 2 uses the word density, which is beyond Grade 2; you can say instead that a floating thing is lighter than the same amount of water.

Common sticking points

- Question 2: putting the coin with floats because it is small and light. Drop one in water, and say that small or light does not always mean it floats. - Question 1: putting the eraser with attracted if their erasers have a metal sleeve. Show a plain eraser. - Question 4: putting lightning with man-made because it looks like a camera flash. Stress that lightning happens by itself in storms.
