Greenhouse Gas Science
Your child can explain why carbon dioxide traps heat but the main gases in the air do not. Its molecules soak up the heat rays Earth gives off, then send them back.
In curriculum terms
Describe the electromagnetic spectrum and distinguish between short-wave solar radiation and long-wave infrared radiation emitted by Earth; explain how greenhouse gas molecules (CO2, CH4, N2O, H2O) absorb and re-emit infrared through molecular vibration while O2 and N2 do not; distinguish the natural greenhouse effect (which makes Earth habitable) from the enhanced greenhouse effect driven by human emissions; evaluate the relative potency of different greenhouse gases

Try this together
Can your child explain, in terms of light and energy, why CO2 in the atmosphere traps heat but nitrogen and oxygen — which make up most of the air — don't? What's physically different about CO2 molecules?
