Corrected sentence: Camels can go a long time without eating or drinking. They store fat in their hump, and this fat gives them energy and helps make some water.
Easy explanation for a 7-year-old:
- Each camel has a hump that holds fat, not water.
- When a camel cannot find food, its body uses that fat for energy so it can keep walking and living.
- When the fat is used, the body also creates a little bit of water from the fat — so the camel gets some water that way.
- Camels can also drink a lot of water at once when they find it, so they can stay long in the desert.
Short tip: A good short corrected version is: "Camels can go a long time without eating or drinking. Their humps store fat, which gives them energy and helps make some water."
