Greenhouses are essential for various purposes, including feeding hungry populations, cultivating plants for medical research, and preserving plants for future generations. They work by collecting heat in the form of sunlight, which is then trapped by glass or plastic enclosures. This process breaks down infrared electromagnetic waves into different waves that are absorbed by plants inside the greenhouse.
The greenhouse effect is a process that occurs when gases in Earth’s atmosphere trap the Sun’s heat, making Earth much warmer than it would be without an atmosphere. Greenhouses use their glass enclosures to trap solar radiation, which enters through the glass or plastic covering and warms the air, soil, and plants. This process is caused by water vapor, carbon dioxide (CO2), methane (CH4), and laughing gas (nitrous).
This Eco-Schools Greenhouse Factsheet provides a simple explanation of how the greenhouse effect works for children by comparing it to a real greenhouse. The greenhouse effect is caused by four main greenhouse gases: water vapor, carbon dioxide (CO2), methane (CH4), and laughing gas (nitrous). Students can use this factsheet to help them understand how increasing the greenhouse effect will affect plant growth.
In conclusion, greenhouses play a crucial role in various aspects of our lives, from feeding hungry populations to cultivating plants for medical research and preserving plants for future generations. By understanding the greenhouse effect and its impact on our planet, students can better prepare for the challenges of climate change.
