Abstract
An experiment machine demonstrating global warming was developed as an educational tool to let learners experience the greenhouse effect of greenhouse gases, including carbon dioxide. We have demonstrated the temperature rise of carbon dioxide, which is caused by the absorption of infrared rays, at various experimental classes, taught class, on television, and elsewhere with this machine. The first author had carried out other experiments using chlorofluorocarbon gas under the same conditions, but. was unable to maintain accuracy, sometimes even causing the temperature to decrease. However, with the present experiment machine we were able to obtain get high accuracy with this. So, we had carried out experiments of methane gas, which is said a high greenhouse effect. As a result, a greenhouse effect could also be confirmed with methane gas. This will make the study of the greenhouse effect more widely available in educational institutions.
