The Earth’s Chemistry KS3 is a five-mission Year 9 science activity book mapped to the DfE National Curriculum for KS3 chemistry (the Earth and atmosphere). Learners name the crust, mantle and core, sort rocks into igneous, sedimentary and metamorphic and follow the rock cycle, recall that today’s atmosphere is about 78% nitrogen and 21% oxygen with about 1% other gases including argon and carbon dioxide, explain the carbon cycle and the greenhouse gases behind human-caused climate change, and describe finite resources, recycling and how metals are extracted from their ores by reduction. Every question is auto-marked on screen, or the whole book can be printed with a full answer key. Includes teacher, parent and pupil notes and is fully SEND-friendly with high-contrast and large-text modes.
