The difference of 93.94cm between the two temperatures for the Slaters movement is a significant difference. Cotton wool prevents contact of the soda lime with the organisms. woodlice choice chamber experiment conclusion For each environment (dry or humid) calculate the mean speed of the animal (in cm per second or metres per second), and the mean number of turns made per metre travelled. No, kineses are random movements. They have no waterproof waxy cuticle on their exo-skeleton and are therefore more likely to suffer it is seen that woodlice move directly to the dark side of the choice chamber. I am going to place twenty wood lice in the centre of a choice chamber with four chambers around it. As well as Tribolium and woodlice, you could use Calliphora larvae or other invertebrates in a choice chamber. Unlike light sources, these stimuli can be harder to pinpoint and may not vary in clear gradients, making it harder to inform a directional response.
