### In the lessons

In science lessons on materials and chemical change, pupils test which conditions make iron nails rust (corrode) — water and air together — and how paint, oil or galvanising (zinc coating) protect them. In everyday life, salty roads in winter and sea air corrode cars and bikes. Phrases: «corrode away», «corroded pipes», «corroded battery».
