Animals like woodlice are placed in these structures, and their behaviour is assessed by analysing their movement through these compartments. 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). Leave for 10 minutes. Weve done this with earthworms in my biology class. Positive responses result in movement towards a stimulus; positive thigmokinesis describes observed behaviour of woodlice they move less when in contact with a surface above or below their body. This response can be important when reacting to less directional stimuli like temperature or humidity and doesnt vary in space in clear gradients. Includes introductory and explanatory videos, fact sheet and worksheet lesson plan (x 2 differentiated). A choice chamber allows you to change conditions in different parts of a container while keeping the animals under investigation out of direct contact with any chemicals used.

In a kinesis response, woodlice move faster if the temperature drops below or rises above a specific optimal range in their current location. All living beings must constantly adjust to their environment to survive. Silica gel beads can simulate a dry area because they absorb moisture from the air, while wet cotton in another compartment can replicate damp conditions.
