lesson 4: wildebeest and rainfall
every year, over a million wildebeests travel across the wide plains of east africa in a journey called the great migration. they move between the serengeti in tanzania and the masai mara in kenya. this migration happens because of rainfall.
rainfall decides where the wildebeest go and when they move. when the rain falls, it helps new grass grow. the wilderness follows the rain because it needs fresh green grass and water to survive. they eat grass every day, and they must find water to drink, especially during the hot months.
scientists believe wildebeest can sense where it has rained, even if it is far away. they travel together in large herds, sometimes walking for many days and nights. along the way, they cross rivers and face dangers from predators like lions and crocodiles.
during the dry season, there is little rain, and the land becomes dusty and dry. the rivers shrink, and the grass turns brown. wildebeest must travel to find places where it has rained recently. when the wet season begins again, the wildebeest return to the southern serengeti. this area becomes full of fresh grass and is the best place for mothers to give birth to their calves.
rainfall is important not only for wildebeest but also for many other animals. zebras, gazelles, elephants, and even predators depend on the changes that rain brings. when rain falls, life returns to the land. the grass, trees, and rivers all come alive again. rain helps keep the ecosystem of the serengeti healthy and balanced. without regular rainfall, life for the wildebeest and all other animals would be very hard.
open-ended questions

1. how does rainfall affect the movement of wildebeest?
2. what do wildebeest look for when they follow the rain?
3. what challenges do wildebeest face during their migration?

Explanation:

1. La lluvia determina dónde y cuándo se mueven los gnu. Durante la estación seca, viajan a buscar lugares con lluvia reciente. Cuando comienza la estación lluviosa, regresan al Serengeti.
2. Buscan pasto fresco y agua para sobrevivir.
3. Cruzar ríos y enfrentar peligros de depredadores como leones y cocodrilos.
