Year 3 have been scientists this term, investigating rocks. Our big question for the topic was ‘Do rocks last forever?’  To help with answering the question we walked to the cemetery to see how some sedimentary, metamorphic and igneous rocks have weathered over time. We decided that rocks do not last forever but show signs of weathering. Some rocks, like granite, weather more slowly than others, like limestone. The children showed a great understanding of rocks and used their scientific thinking to deepen their understanding.
