Today's Modeling Your World class began with a refresher course presented by Bob Panoff, Bob1. Some of the students were curious to what the SUCCEED programs was all about. To help quench their curiosity, Bob1 explained that SUCCEED stood for Stimulating Understanding of Computational Science through Collaboration, Exploration, Experiment, and Discovery.

After their discussion about the SUCCEED program the students learned about "agent models". An agent model is called such each of the individual object in the model follow a given set of rules. The collective behavior that results can be very different even if the rules for each agent are only slightly changed. Even though the name of this concept had not revealed the student were able to determine that Galaxsee and Surface were agent models. The students played a game in which everyone stood up initially and would either stand up or sit down when he snapped his fingers. Bob1 then told the students whose name began with a vowel to sit down. After this, Bob1 snapped his fingers in which the students who were standing up sat down and the students sitting down stood up. The students participated in several different stand up sit down rules for this game.


The above are models of a forst of tress and the effects of a forest fire

Concluding this game the dove into the computer models. The first model that the students interacted with was "The Game of Life". This was a very simple computer model where agents either lived, died, or reproduced. The students experimented with this model and then compared result. The student found out that changing one variable would affect the entire result. Next, the students brain stormed practical occupations for the use of these models, such as a city designer.

Another model that the explorers were able to view was the forest fire model, which is a model with an obvious practical application. By using this model foresters would be able to predict how may trees to remove to make a forest fire more improbable.

Following the explorers short break Chris gave an introduction about himself in a short rap. The students modeled the life cycle of plants and animals in a program called Stella®. With the students newfound knowledge of Stella® it will allow the discovery of more complex model.
