Slime molds, like Physarum polycephalum are part of the kingdom Protoctista. A new genetic algorithm based on modified Physarum network model for bandwidth-delay constrained least-cost multicast routing Mingxin LiangChao GaoZili Zhang Natural Computing The mold yellow explored and filled the maze left.

This is probably amosboid least understood of the five kingdoms of life; the others being animals, plants, fungi, and bacteria.

In this advanced biology science fair project, you will attempt to repeat the research results of Nakagaki, et al. Variations Try other maze designs. Establish a culture of Physarum polycephalum and determine if it can find the shortest distance between two food orgaanism in a maze.

Intelligence: Maze-solving by an amoeboid organism

Keep in mind as you evaluate how many materials you will need that you will be running at least six trials of this experiment, and they can be run concurrently. This video shows how the slime mold Physarum polycephalum can find the shortest distance through a maze.


Place food moistened oats on an agar plate in a triangle and inoculate the plate with Physarum polycephalum. Is intellignce the minimal distance possible to connect the food sources? Why do grunion fish lay their eggs based on the moon and tides? What is the final shape of the organism?

They form colorful gliding masses as they creep over decaying wood and leaves. For example, you could try printing intelligenve maze on the filter paper directly, then coloring in the maze with crayons or other material the Physarum polycephalum will not grow over.

With a name like slime mold, it’s understandable that you would expect these organisms to be ugly and disgusting. Share your story with Science Buddies! If the Physarum polycephalum organism is chopped up and dropped into a labyrinth a mazethey put themselves back together and start to move. At the same time, if a food source is placed at the entrance and exit to the maze, they avoid dead ends in the maze intellihence form a connection as a single tube between the food sources.

Make the diaphragm small and focus on the bright yellow veins. Very high High Moderate Low Very low. Independent confirmation of results is a common and important practice in science. You can find this page online at: The goal is to address the question “Does the organism Physarum polycephalum demonstrate qualities that can be termed primitive intelligence? It should be about 4 cm x 4 cm when printed out. It changes its shape as it crawls over a plain agar gel and, if food is placed at two different points, it will put out pseudopodia that connect the two food sources.
