In the lessons

In home safety, bleach is dangerous: it can burn skin and eyes and is poisonous if swallowed. Never mix bleach with other cleaners (especially ones with ammonia or acids) — this makes toxic gas. Keep it locked away from children, in its own bottle. In science, sunlight can bleach colours, and coral bleaching happens when oceans get too warm. Phrases: bleached by the sun, coral bleaching, a splash of bleach.
