Filament could be in any colour, except for the very bright ones.
Overview and Background
Behavioural experiments are very interesting for students at every stage of education - this specific investigation is concerned with a causal explanation of the behaviour shown by woodlice in a maze.
The idea of example activity is to force a woodlouse to make a turn in a specified direction, and then give it a choice of turning left or right.
Lesson Plan and Activity
The video below presents a demonstrative experiment that can be done using this maze:
Several - usually around 10 - movable elements (block_blend.stl) should be printed with the maze (maze_blend.stl). They allow blocking of selected paths of the maze. They allow modification of the paths in accordance to the requirements of an experiment.
A corner created by insertion of movable elements into the initial grid.
This model was projected to also function as a building block. Therefore, with several printed mazes and a corresponding number of movable elements, more complicated setups can be created. This feature may be useful when designing some advanced experiments, like the ones on the pictures:
Left - a single printed maze, Right - a bigger maze created from four single ones
a very long one
a Z shape - why not?
