Year 5 started their Science this week by consolidating prior learning on the properties and changes of materials with a lively game of 'Find Someone Who'. This active revision, which included concepts from Year 3, generated a wealth of rich discussion and ensured strong information recall. Energized by this, we launched into our new topic: hardness. Students tested various materials, using a nail to scratch different objects and ranking them from hardest to softest.  We then evaluated our investigation in terms of its reliability.
