Stratus clouds – A blanket of cloud – Weather science

By |2019-02-11T13:47:05-07:00August 20th, 2017|Physics|13 Comments

Stratus clouds (thanks to NASA) What are stratus clouds? If you see stratus clouds, that's the time to get inside and stay there. Stratus clouds mean rain if it is warm and snow if it is cold. They look like a huge gray blanket that hangs low in the sky. Sometimes stratus clouds are on the ground or [...]

A bolt of lightning in the sky Hot air and cold air are constantly moving around the Earth, as the hot air rises and the cold air sinks - that's what makes wind. Sometimes as this airmoves around, it gets more exciting than just wind, though. A thunderstorm begins when the wind picks up a lot of water from the [...]

See the steam coming out of this kettle? You can make your own clouds and see how they work. Just take a tea kettle and fill it full of water and put it on the stove to boil (make sure this is okay with your folks). When the steam comes out, it makes a white cloud - that's the [...]

Saturn – Planets – Astronomy

By |2018-05-31T11:49:18-07:00August 19th, 2017|Physics|0 Comments

Saturn, as seen from space After Jupiter, Saturn is the next farthest planet out from our Sun. In some ways, Saturn is a lot like Jupiter - it's very cold, and it's mostly made of an ocean of hydrogen molecules, with some helium and a little bit of other things. Like Jupiter and the other planets around our Sun, Saturn [...]

Neptune from space Neptune is the farthest planet from our Sun. Neptune is the only planet that is so far away that you can't see it without a telescope. Neptune (NEPP-toon) is an icy planet, about the same size as Uranus. Neptune's probably a lot like Uranus in other ways, too. Neptune has a rocky core [...]

Meteors – Shooting stars – Astronomy

Lyrid meteor shower Meteors or meteorites are bits of rock (like granite) and ice - usually a mixture of rock and iron and nickel but sometimes just rock or just iron - from out in space that get sucked into the gravity of the Earth and fall through our atmosphere to the ground. Usually this is because a comet has passed close enough to the Earth for [...]

Salt water and ice: A salt truck spreading salt on the road Why do people put salt on the roads? You can easily see that salty water freezes at a different temperature than fresh water. If you live somewhere where it gets cold in the winter, you probably already know that you put [...]
