Summary Introduction
To review:
The simple experiments in order to test whether the organism prefers dark or light environments, moist or dry conditions, and oats or sugar as a food source.
Introduction:
Physarum is known to be slime mold that resides in shady, moist, and cool regions such as logs or decaying leaves. These are generally sensitive to light and light can repel the slime mold.

- Dlanama Activity adapted from https://www.nwabr.ora/sites/default/files/Planaria Student.pdf The Planaria research project: During this investigation, you will conduct an experiment to explore the regenerative properties of Planaria. You will have three Planaria per team 1) Two "experimental" Planaria a Experimental Planaria #1: This Planarian will be cut into half (transverse plane: see figure below), that will result in two fragments with a front (anterior) and rear section (posterior). Every team in the class will do the same! (Why is it important to have experiments repeated multiple times?) b. Experimental Planaria #2: This Planarian will be cut in a manner determined by your team. 2) A "control" Planaria which will not be cut. Important things to remember: It is your responsibility to work in a cohesive manner with your team members. This project will span over three class periods.
