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.

Many people believe that you should keep your head covered during cold weather, as most body heat is lost through the head. It’s certainly true that any part of your body that’s exposed to cooler air will lose warmth; heat always moves from something warm to something cooler (that’s called the second law of thermodynamics). And our heads and faces are more sensitive to changes in temperature than other parts of the body.

With poor living conditions and water shortages increasing every year across the world, the question of how to clean water efficiently is becoming ever more important.
 

Does Everyone Have Clean Water?

When you have clean, safe water available at the turn of a tap it’s very easy to take it for granted. But almost 750 million people don’t have access to clean water; that’s one person from every ten in the world’s population. There are many reasons for this, from poverty to poor management by governments.
