Squash is a seasonal vegetable. It is very susceptible to frost and heat damage, but with proper care it will produce a bumper crop with very few plants. There are many varieties of summer squash to choose from, including zucchini. The main difference between winter and summer varieties is their harvest time; the longer growing period gives winter squash a tougher, inedible skin.

Simulation is the imitation of the operation of a real-world process or system over time. The act of simulating something first requires that a model be developed; this model represents the key characteristics or behaviors/functions of the selected physical or abstract system or process. The model represents the system itself, whereas the simulation represents the operation of the system over time. Simulation is used in many contexts, such as simulation of technology for performance optimization, safety engineering, testing, training, education, and video games.
