Q: What test is used to detect the presence of hydrogen?Ī: The squeaky-pop test (aptly named after the sound it makes in reaction to a flame).ĭid you know that the Earth's atmosphere is made up of 78% Nitrogen and only 21% Oxygen? (The other gasses are Argon which is 0.93% and Carbon Dioxide which is 0.04% with traces of neon, helium, methane, krypton and hydrogen, as well as water vapour). Q: What is the name for the process of a liquid becoming a gas?
Q: What word would you use to describe a material that is see-through?įun Fact: Elephants are the only animals in the world that have 4 forward-facing knees! Every other 4 legged animal has at least one pair that go the other way. Q: What are the three major types of rocks?ĭid you know that sedimentary rock covers about 75% of the Earth's surface? BUT below that 95% of rock under the crust are igneous rocks! Q: What force stops humans from floating into space? Q: How long does it take the earth to fully orbit the sun?ĭid you know the sun is 93 million miles away from the Earth? That means although it looks tiny it is actually really massive! Q: What do you call something that is a poor conductor? Q: How many planets are there in our solar system?įun Fact: This fun acronym will help you remember the order of the planets from the closest to the sun to the farthest: My Very Easy Method Just Set Up Nine Planets = Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. Q: What do you use to test a scientific theory? Q: Where do humans get their energy from?įun Fact: Cucumbers are actually fruits, not vegetables! They are part of the melon family. Q: What is the solid version of water called? Think you know a lot about Earth and our moon? Test your knowledge about our planet, and see how much you know about the basic elements and objects found in our galaxy and in our solar system.Fun Fact: The adult human body has 206 bones in it.ĭid you know that the Earth revolves around the sun which determines the length of our day and also our seasons? The sun rises in the east and sets in the west. (If it sounds like it's getting a bit cluttered up there in space, it kind of is.) For instance, did you know scientists think there could be a giant but undiscovered planet lurking around Neptune?Īnd there's more in our solar system than just that - in fact, just spinning around our own planet there's an estimated 500,000 bits of orbital debris measuring between one and 10 centimeters in diameter and an additional 21,000 bits of debris larger than 10 centimeters. The galaxies, planets (including Earth) and other objects we see (and don't yet see) in our solar system, including dwarf (minor) planets, moons, comets and asteroids (and leftover dust and gas), were also formed in this event.
And, when doing so, it began moving in a big circle - creating and then spinning around a small star that would eventually become our sun. Scientists believe our solar system, which is called simply the Solar System, was formed when a giant cloud of dust and gas collapsed under the weight of its own gravity. Or when you saw the three brightest stars in Orion's Belt: Rigel, Betelgeuse, and Bellatrix. Maybe you became interested in celestial bodies when you first found The Big Dipper, which is part of a constellation called Ursa Major. When you look up at the sky on a clear night, you'll see endless stars, our moon, maybe another planet shining back at you. Or maybe you desired to boldly go where no one has gone before. Maybe you were taken in from stories of a long time ago, in a galaxy far, far away.
