Modeling the movement of agents (people,molecules, cars or ideas) is an important part of modeling systems. Different agents will have varying amount of randomness in their “walks” which can have an impact on systems. In this activity, students will apply the concept of randomness to a simple StarLogo program in which the agents will use ‘random’ blocks to ‘wiggle’ as they move around SpaceLand. This programming activity follows the ‘What are the Chances?" activity.
