Science News – Solar Storms Due to Hit Earth
This weekend the Earth is due to be hit by a pair of solar storms that might affect radio and satellite communication. But how and why does this happen?
What Does Solar Mean?
Anything that is related to a sun is commonly described as being solar. Our sun is a typical medium-sized yellow star which is about 5 billion years old. Its surface temperature is about 5,500°C, but even that isn’t as hot as its superheated centre. Some parts of the sun’s surface are cooler, with a temperature of between 2,700–4,200°C, and these appear darker when viewed through specialised telescopes. These cooler patches are caused by fluctuations in the sun’s magnetism and are called sun spots.
Tween Chef – Simple Solo Cooking for Kids
Simple solo cooking – learn how to make these dishes with minimal assistance from adults.

Often they are only allowed to stir things, or decorate the cakes. Most tweens are capable of cooking the entire meal, but often they lack confidence, or are worried about burning themselves, or spilling things.
You will learn basic cooking techniques, and how to stay safe in the kitchen, and as time goes on we will do more complicated dishes.
