Start with a general introduction (slides). The introductory slides start by defining competition, which is an interaction between organisms in which both are harmed when trying to use the same resource. List some of the resources that the organisms can compete for and how niche overlapping can affect the interspecific competition. This introductory part should last only about 15 minutes.
Participants can play the resource-competition game. The idea of the game is to demonstrate how overlapping niches and resource availability or densities can affect interspecific competition. The game has two versions that differ in their duration.
1) In a shorter version (ca. 15 – 20 minutes), participants are divided into two groups “competition” and “no competition”. Participants are competing for the resources in groups of three people for 4-6 rounds (see rules here).
2) In a more extended version (ca. 30 – 40 minutes), participants play the few rounds in the “no competition” group. After which the game is reset, and all the players play the game in the “competition” version. Play resource competition game at least for 4-6 rounds.
Extra: You can visualize the result by drawing how the number of life chips changes with each round for each species and scenarios (no competition vs competition) separately. The x-axis will indicate the number of rounds, and the y-axis the total number of life chips per species for each round. You can also use this excel sheet to visualize your results.
