The Stone Age is a period of history that started more than 2 million years ago and lasted until about 5,000 years ago. It’s called the Stone Age because the ape-like people, known as ‘hominins’, who lived at that time used stone materials to make tools and weapons.
But my 5-year-old wants to know where Stone Age people came from. So let’s find out more about our ancestors and human evolution…
Milk is a white-coloured liquid food made by mummy cows to feed their baby calves. It contains all the nutrients that a young calf needs to grow – and that makes it a good food for humans to drink too.
In our family, we drink a lot of milk – about 8 pints each week! We put milk in our tea, on our breakfast cereal and in our baking. And we eat other things that are made from milk, like butter and cheese and yogurt and ice cream.
But over breakfast the other morning my 5-year-old was thinking about the milk on her cornflakes and she wondered – is it a juice? So let’s find out…
My 7-year-old said she’d like some unicorn bunting to decorate her bedroom. We found some instructions online, bought some fabric and got out the sewing machine. But the cotton fabric we had bought was creased and folded. We had to make it all flat and smooth before we could draw on triangle shapes for the flags and cut them out.
So, why does fabric get creased? And why does pressing it with a hot iron make the creases go away? The answer is all to do with chemistry, so let’s find out more…
