Three Science Facts to Impress Your Friends and Teachers

1. Where do clouds come from? When the sun warms up the air, water from oceans and lakes and rivers begins to evaporate. This means it turns into water vapor (a gas that you can’t see) and begins to rise through the air. As the air gets cooler, the vapor sticks to dust in the atmosphere. Eventually the rising water vapor comes together to form a cloud. When the cloud grows heavy with water droplets and it can’t hold any more, the water falls from the clouds and it begins to rain. Fog is a cloud that has formed at ground level.

2. A submarine (called a sub for short) is a large vessel that travels underwater. It is large enough for a crew of people to live inside it. Scientists use subs to explore beneath the ocean, and the navy uses them to help keep the oceans safe. Some can go as deep as eight hundred feet. A sub is also a kind of sandwich, but it would get very soggy underwater and no one would want to eat it. Except for Pockets, if it were a tuna sub.

3. Magnetite is a mineral found underground in parts of the world. This is where the word for magnet comes from. Magnets can push and pull on things with an invisible force by creating what is called a magnetic field. The magnetic field attracts certain metals like iron, nickel, and cobalt. Anything made out of these materials will stick to something magnetic.
