Task 2: Magnetic properties of metals and alloys
Topic: Metals
Level: Primary (1.–5. Graders)
Thematic Unit:
Subject: science
Recommended age of pupils: 6–11 years old or older
Time allocated: preparation: 5 minutes, implementation: 10 minutes
For every working group of pupils, the teacher prepares metal objects– iron, aluminium, copper and out of alloys – brass, bronze and chromium steel. Then the teacher prepares a magnet for each pupil in every group.
Pupils number each samples of metals and alloys, describe the look – colour and sheen and write it in the table. Based on their own experience, they predict if the magnet will attract the metals and alloys or not. After that, pupils either confirm or disprove their presumptions by placing the magnet towards the objects. They write their findings in the prepared table. The teacher, together with the pupils, determines which metals and alloys pupils were working with.
