What are the gases that make up air ks2?
It’s a mixture of different gases. The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen.
What are the 3 main gases in the air?
The dry composition of the atmosphere is mostly nitrogen and oxygen. It also contains fractional amounts of argon and carbon dioxide and trace amounts of other gases, such as helium, neon, methane, krypton, and hydrogen (NASA).
What are the gases in the air?
Standard Dry Air is made up of nitrogen, oxygen, argon, carbon dioxide, neon, helium, krypton, hydrogen, and xenon. It does not include water vapor because the amount of vapor changes based on humidity and temperature.
What are the 4 gases in air?
Earth’s atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent.
What gases are in air for kids?
In addition to nitrogen and oxygen, air consists of small amounts of the gases argon, neon, helium, and methane. Besides gases, air also contains water vapor, dust, pollen, and bacteria.

Why is air a gas for kids?
Air consists of a mixture of gases. These gases consist of tiny particles called atoms and molecules. They are so small that they cannot be seen. Atoms are the smallest parts of chemical elements, and molecules are combinations of different chemical elements.
What are 5 facts about gases?
Gas Facts for Kids
- Like solids and liquids, gas is a common state of matter.
- Pure gases are made up of just one atom.
- Elemental gases are made up of two or more of the same atoms joined together.
- Compound gases contain a combination of different atoms.
- The air we breathe here on Earth is made up of different gases.
How are gases like particles in the air?
Gas particles will continue spreading outwards until they are restricted by a container. When a gas is contained, it will fill the space in all directions. Gases are often invisible, like the gases in the air we breathe. Some can be seen, however: fizzy drinks have gas bubbles, and fire combines several gases at high temperatures.
Which is heavier a gas or an air?
Gases can be either heavier or lighter than air. Show the equipment to the class and ask them what you are going to find out. Discuss, predict and carry out the test. Discuss what will happen to balloons when they are inflated by helium and carbon dioxide.
