Greenhouses are the perfect place for sprouts
to call home. Greenhouses work by allowing
sunlight to pass through the clear walls to be
absorbed by soil and plants. The plants and soil
then reflect the light as heat energy, which
warms the air inside the greenhouse. The walls
of the greenhouse stop the heated air from
escaping, so it stays trapped in the greenhouse,
allowing the temperature inside to stay warm -
even in cold weather! Next >>
