               Define the Problem
                Greenhouses are buildings designed to protect vegetables and other
                plants during cold seasons.  They are built using glass or plastic, which
                trap radiation from the sun and increase the temperature inside the
                greenhouse.  Your task is to design and build an effective greenhouse
                model for a small plant.




                            Constraints: Your model must be able to hold a small plant.





                            Criteria: The internal temperature of your model greenhouse
                            must be higher than the starting temperature after 20 minutes
                            under a light source.  28
