My parents live near the sea and my daughters love going to visit Granny and Grandad, especially when they get to spend an afternoon on the beach hunting for crabs and fish in the rockpools.
The sea is a fascinating natural beauty but how was it formed? Where did all the water come from? How heavy is it? And how can you hear the sea in a shell?
Grasses are a family of plants that includes cereals, bamboo and the short green stuff that makes up garden lawns. They grow all across the world. But what is it about grasses that helps them to grow in so many different habitats?
Cows have been farmed by humans for thousands of years. They provide meat for us to eat and milk that we can drink. We also use cow hide (skin and fur) to make clothes, shoes and shelters, and we use their dung (poo) as manure to make soil better for growing crops!
But which came first – the cow or the farm?
“If humans evolved from monkeys, why do they still exist?” asked one of the children at my daughter’s school. It’s a great question about the theory of evolution and how there came to be so many different types of creatures on Earth.
There are many different forms of life on Earth – from bacteria and fungi, to plants and animals.
Evolution is a theory that explains how there came to be so many different types of living thing on Earth. It describes the gradual changes that happen when creatures reproduce in combination with changes to the places in which they live.
