The children are shown the Timeline of the Human beings. It starts with the paleolithic era and shows how the first human beings appeared just after a major ice age, how they ate raw meat nad wore no clothes. It continues to show how fire was discovered probably by accident, how fire was then used to keep them warm, protect them from wild animals and allow them to cook their food.
Further, the children can see how they made their first tools from flint and animal bones, how they started to work together and hunt and how they moved around as the weather became colder to warmer places.
