Creation and the Jewish Bible

By |2017-08-23T21:56:08+00:00August 23rd, 2017|Religion, West Asia|

God creates the Sun and the Moon, in a medieval European painting Many of the Jewish people in West Asia believed that at the beginning of time God created order out of Chaos. This is what is written in the beginning of the Bible, in the book called Genesis. Jewish ideas about the beginning of the [...]

What causes wind (Hot air rises) – Wind and weather Science

Hot air balloon - hot air rising is what causes wind Hot air is lighter than cold air When something is hot, its molecules are farther apart than when it is cold. When air is hot, its molecules are further apart, so it takes up more room. That makes hot air lighter than cold air, because the [...]

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 [...]

What’s the sun made of? – Astronomy – Science

The sun from space The Sun is a star, just like billions of other stars in the universe. Our Sun probably formed a little more than four and a half billion years ago, just a little bit before the planets formed around it. It's not one of the older stars in the Universe. Probably some of [...]

Saturn – Planets – Astronomy

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 [...]

What are planets? Astronomy – Space science

What are planets? The planet Venus from space Before there were planets For several hundred million years after the Big Bang, there were no planets, only stars. Planets couldn't form until the first stars ran out of fuel and exploded into supernovas, about 14 billion years ago. The supernovas spewed out thousands of tons of carbon, oxygen, iron and other elements into space. Planets [...]

The Moon – Astronomy – Physics

Earth's moon (about 239,000 miles from Earth) (That's almost ten times as far as going all the way around the Earth) Nobody knows exactly how the moon formed, but this is one possibility. After the planet Earth formed (along with the other planets), about four and a half billion years ago, during the Hadean Eon, there were [...]

Mars, the red planet – Astronomy

Mars, the way the planet looks from space The closest planet to Earth is Mars, and Mars is also the planet that seems most likely to have life on it besides our own Earth. It's the next planet further away from the Sun after Earth. When you look at Mars from Earth, it looks reddish, and even [...]

Jupiter – Planets – Astronomy

Jupiter from space Jupiter (named after the Roman god Jupiter) is the next planet further out from our Sun after Mars. But Jupiter is much, much further away from the Sun than Mars is. If the Sun were the size of a penny, then Earth would be about six feet away from the Sun. And Mars would be about ten [...]

Eclipse of the sun – Astronomy

By |2018-05-31T11:49:27+00:00August 18th, 2017|Physics|

Eclipse of the sun, showing the corona An eclipse of the sun happens whenever the moon gets between the Earth and the sun, so that the moon blocks your view of the sun. Depending on where you are standing on the Earth, you might see the sun completely blocked (as in these pictures) or only partly blocked, or [...]
