Ruth is a professional archaeologist. She spends most of her time below ground, running archaeological excavations on busy construction sites. If you have ever wondered how to become an archaeologist, read on!
Tips for Moving to a New School
Moving to a new school is always scary, whether you’re moving from primary school to high school or into a new school in a different area. What can you do to make it easier?
My kids are old hands at this because they’ve moved school so often, even going into schools in a new country where they haven’t known the language. We’ve lived in Germany, Switzerland and UK and they’ve been to local schools speaking German, French and English. It wasn’t ever easy but they’ve made great friends who they still keep in touch with now that they’ve moved on.
I asked them for their advice on moving to a new school.
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.
Green and Growing: The Life of a Seed
As you know, there is a vast number of different kinds of plants growing all over the world, from snowy slopes to Amazon rain forests to dusty deserts: plant life is everywhere. So how does it all work? Lets start with seeds.
The Life of a Seed
Picture a seed – I am sure you have all seen them. It will have a hard outer shell to protect it. When it has found the right conditions of warmth and moisture, this shell will crack or split as a root pushes its way out to take hold in the soil. Then the plant will start to grow and a shoot will make its way upwards, with the root growing down, to draw moisture from the ground and provide some balance for the plant, keeping it firm in its place.
Just like you and me, plants need food to grow. Their food is very different from ours, of course! Here’s what they do: the leaves draw water up from the roots, through the stem, and they also soak up sunlight and air. These three things combine to make food in the leaves, where it is stored. Now think of an onion. It is formed to store the food for the plant.
