The forest has been dry and scorched for weeks. One afternoon, a hot wind blows and storm clouds gather. Lightning strikes a tree in the meadow and ignites the dry vegetation. No life remains in the burnt forest. As the years slowly pass, seeds start to germinate and small creatures inhabit the forest. Students will learn that fire is sometimes good for the regeneration of forests.--Ministry of Education website.
