Year 8 Science (Biology, Chemistry & Physics) Curriculum UK
Year 8 Science investigates the digestive and respiratory systems (aerobic and anaerobic respiration), the periodic table and chemical reactions (combustion, reactivity series, displacement), light and sound wave behaviors (reflection, refraction), and electromagnetism.
Statutory Key Aims & Expected Attainment:
- Describe the process of respiration and how the human gas exchange system works
- Understand the periodic table: metals, non-metals, Group 1 alkali metals, Group 7 halogens
- Describe chemical reactions: combustion, thermal decomposition, and displacement reactions
- Explain wave phenomena including reflection, refraction of light, and sound wave frequencies
