Still in their coats on a sunny day(Thanks to [seattle + beyond]) To see what a difference it makes whether sunlight hits the Earth directly or at an angle, just think about a sunny day in summer and a sunny day in winter. In summer, when the sun is out it soon gets very hot. Even cloudy days, when the sunlight has to come [...]

Rain project – Weather science

People driving cars in the rain Some of the tiny particles inside the clouds - the cloud seeds - are made of pollution from cars and factories. They're little particles of carbon from burning gas, or other pollutants. Because people drive more on weekdays than on weekends, there is more and more pollution [...]

Nuclear fusion – Simple Physics

The Sun shining from space: nuclear fusion in action. The first fusion reactions Fusion reactions are how the first stars got started. Soon after the Big Bang, hydrogen atoms began bumping into each other and merging into one bigger helium atom. Four atoms with four nuclei - centers - mixed together into one atom with a bigger nucleus. What's [...]

What is heat? Simple science – Chemistry

What is heat? A big campfire throws some serious heat Definition of heat When molecules of any kind of atoms get more energy in them than they had before, they move faster, and we call that "heat". When the molecules move faster, they hit against each other and bounce apart. So they end [...]
