This week, the Year 3 scientists recapped on the previous lesson learning all about rocks. They started by talking with their peers about different rock groups: igneous, sedimentary, and metamorphic. The main part of the lesson was about weathering, which is how rocks get broken or worn away over time. They looked at physical weathering (like freezing water), chemical weathering (like acid rain), and biological weathering (like tree roots growing through cracks). There was lots of "talk time" for the children to use their oracy skills, especially when discussing which rocks make the strongest walls. By the end, they could explain how weathering changes rocks and pick the best ones for different jobs.
