===Phase 2 :: Time Lapse – Growth Research :: Social Slime===
===Phase 2 :: Time Lapse – Growth Research :: Social Slime?===
In the second phase, Physarium polycephalum was studied using time-lapse photography. Time-lapse recordings were tried out in different settings in order to build up a functioning set-up for the examinations/recordings.

For experiment one, a circular strip was removed from the agar layer. Oats were added to the excised area to surround the slime mold with it. The cutting out resulted in a shrinkage of both layers, and an unintended expansion of the cut-out area. Nevertheless, a certain urge towards the food-covered area could be observed, which stands contradictory to an urge to discover and thus a "social behavior“. In the second case, a circular area of finely ground oatmeal was applied to the agar layer. The growth of Physarium polycephalum in this experiment contradicted the previous study. The slime mold spread over the entire agar surface, regardless of the circular food source.
