When fuels containing carbon are burned, it is common for carbon dioxide to be made.
Carbon dioxide is a compound with molecules that each contain one carbon atom and two oxygen atoms.
Less than 1% of the Earth’s atmosphere is carbon dioxide.
Carbon dioxide is a greenhouse gas.
In the atmosphere, some gases are greenhouse gases and have properties that enable its temperature to rise over time.

Burning hydrocarbons results in harmless products.

Teach about carbon dioxide being a greenhouse gas, and the impact on global temperatures.

Carbon dioxide - Carbon dioxide is a compound with molecules that each contain one carbon atom and two oxygen atoms.
Atmosphere - The atmosphere is a layer of gases that surround a planet. It may contain small amounts of solid and liquid particles.
Greenhouse gas - Greenhouse gases absorb infrared (IR) radiation emitted from Earth.
Global warming - An increase in Earth’s surface temperature is known as global warming.
