Magnetic and Non-Magnetic Materials
Lesson: Science
Class: Year 3 Year: 2022 - 2023
We have been grouping and observing magnetic and non-magnetic materials and metals. We have talked about metals that are magnetic and those that are not and discussed why, understand ferrous meaning containing iron. We found an anomaly... 1p and 2p coins, we had one coin from 1980 that wasn't magnetic and one from 2011 that was magnet. After research we found out that in 1998 copper coins now have steel cores rather than being pure copper. We have also talked about silver, just because on object is the colour silver doesn't mean it is silver metal but could aslo be many other metals.
