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.

What is The Point in Learning … History

Have you ever sat in a Maths class wondering if you will ever have to do long division without a calculator once you leave school? Or silently cursed your Geography teacher while learning about the formation of oxbow lakes?
And History? That’s all in the past and irrelevant, isn’t it? In this series of articles, we will look at some of the subjects we learn at school, and try and answer the question: What’s the point in learning this?

Last time we looked at uses of Physics, both in day to day life, and in careers. Today we will focus on History – the study of the past and how our society came to be as it is. Here are some ways in which studying History is useful to us:

Thinking by Elisabeth Haslam

When we study history we don’t just learn lists of facts and dates off by heart. We read lots of opinions about what happened and why, and come to our own conclusion. We base these opinions on two types of material, primary sources which are texts and drawings created at the time of the history we are studying, and secondary sources which were written after the event.
