If you use a lamp to establish a light/ dark gradient, the woodlice may in fact be responding to the heat of the lamp. 4. Collect 10 unused Tribolium beetles or woodlice. However, if the organism continues in such adverse surroundings, it will decrease its turning rate (direction change); thus, moving in long straight lines and increasing the chances of reaching a more suitable environment, where the temperature might be milder. The same can be achieved for light stimulation simply by covering part of the dish from any light source, thus creating a dark compartment within the chamber. When moving from a damp area to a dry one, woodlice move faster and change direction more often to return to a damp area. Set up an enclosed environment and divide it into interlinked compartments. In klinokinetic responses, the frequency of turning depends on the intensity of the stimulus. Shar Jackson Children, The lamp should be shining at a shallow angle along the tray. These may result in overall movement out of one area into another. Woodlice are easy to obtain in large numbers, their biology is relatively simple, they are easy to culture, and the common species can usually be recognized with the naked eye: consequently they provide ideal material for student research projects. Woodlouse are attracted to solid objects including each other and when they come into contact, they stop moving, clumping together. Pool the class results as before. Very cool experiment! Woodlice also display Thigmokinesis, a movement or immobilisation response to contact stimuli. Add a fixed volume of distilled water to one side and a fixed volume of drying agent to the other. Woodlice may look like a type of millipede or beetle, but they are in fact related to crabs and other crustaceans! Blue, moisture-indicating silica gel impregnated with cobalt(II)chloride (see CLEAPSS Hazcard) is TOXIC; the Hazcard suggests wearing gloves when handling large amounts, and avoiding any dust. It is a very simple investigation to set up and one that kids loves at it involves searching for insects, and then predicting and watching.
