Choice Chambers animal behaviour investigation! Shrimp and lobster. How did we carry out our experiment? Kineses are random movement responses. All these behavioural strategies will increase the chances of woodlice or any other animal spending more time in favourable conditions (damp and mild temperature) than unfavourable ones (dry, extreme temperatures). Ask students to develop a hypothesis to test relating to damp/dry conditions, light/dark conditions or the presence/absence of another manageable substance (such as the animals main foodstuff). Follow good hygiene procedures during and after handling invertebrates (Note 6). The choice chamber should offer woodlice two environments; damp or dry. Sieve the beetles from the flour before the investigation starts. If you need to lift the lid, you just have to wait a little longer for a new equilibrium to establish.
PDF Woodlice Choice Chamber Experiment Method , Copy Count where the woodlice are every 30 secs. . Taxes are very similar to another kind of response by plants called tropisms. The humid and dark environment prevents them from desiccating (through water content loss from their skin surface) and allows them to hide from possible predators.
