### In the lessons

In science, a thunderstorm forms when warm, wet air rises fast into tall clouds; lightning is a giant electric spark, and thunder is the sound of air heated by it. You see lightning before you hear thunder because light travels faster than sound: count the seconds between and divide by 3 to get the distance in kilometres (by 5 for miles). In safety: when thunder roars, go indoors; avoid tall trees, open fields, water and metal fences. Phrases: a severe thunderstorm, thunderstorm warning.
