One requirement for my ILO is that I learn the science behind my geodesic dome and the science behind a greenhouse. I decided to learn all about the science involved with a greenhouse. What I really wanted was a short, easy to understand video to attach to an explanation on my Google Site. I spent some time on the internet and finally came across a perfect video. It's short, easy to understand, and includes an animated visual. I found this video on YouTube and added it to my Google Site. The video explains that the key to the greenhouse science are the glass (or polycarbonate walls). Solar radiation (sunlight) travels through the glass, reaching, and warming the ground. When the ground releases this thermal radiation it rises as heat does. This heat is trapped in the greenhouse though. It can't go through the glass ceiling like the sunlight can. With heat continuously being trapped in the greenhouse, the temperature within begins to rise. The greenhouse becomes a warm environment, that also gives the vegetation access to sunlight. Even if the weather outside the greenhouse is cold, the temperature is kept warm inside; proven by this science. For anyone trying to understand the basic concept of how a greenhouse works, this video is perfect for you. It also touches upon the greenhouse effect; global warming. These two concepts are exactly the same, hence the name.
