Prehistoric Art
When we visit art galleries or learn about art in school, we tend to think of paintings on canvas, sculpture or photographs. Often these will be clearly recognisable as people or objects like food and flowers, and we can relate to them as familiar in some way.
Art and pictures have been around ever since people first were recognised as human by historians, in pre-historic times. Prehistoric simply means history which dates before written accounts are available to study. The earliest humans did not have writing with which they could communicate and this means that art and pictures were even more important to them.

Girls are told, all the time, that there are things they can’t do because, well, they’re girls. I’m here to tell you: it’s not true.
Let me tell you about a girl I know.
Have you ever wondered…why leaves change colour in autumn?
Autumn is a season of change; the weather gets colder, there’s less daylight and leaves change colour and fall from plants. But why does this happen?
Why Do Plants Have Leaves?
Leaves contain a chemical called chlorophyll (pronounced KLO-ro-fil), which as well as giving them their lovely green colour also helps create food for the plant. The leaves act like tiny solar panels, and use the sun’s energy to convert water (from the ground) and a gas called carbon dioxide (from the air) into sugar and oxygen. This process is called photosynthesis (pronounced foto-SIN-theh-sis), and the sugar is what the plant lives on.
