Woodlice Behavior Experiment

Aim: To investigate the effect of light intensity on the behavior of woodlice (Porcellio scaber) in regards to their change in speed.

Variables:

Variable How can it be controlled?
(IV)
- Light intensity - The light intensity will be controlled by the knob on the lamp throughout the experiment. In addition, the light intensity will be controlled by closing the windows and doors in the classroom as well as turning off any other light source besides the one lamp needed to carry-out the experiment.
(DV)
- Distance in between the lamp and the woodlouse
- Speed of woodlouse - The distance between the lamp and the woodlouse will be controlled by measuring its distance with a ruler and maintaining that distance throughout the whole experiment.
- The speed of the woodlice will be controlled by measuring the distance it moves in the controlled time period by counting the amount of squares it crosses.
(CV)
- Woodlice
- Time
- Temperature - The woodlice will be controlled by using only one type of woodlice (Porcellio scaber).
- The time will be controlled by a digital timer.
- The temperature will be controlled by using a non-heated lamp throughout the experiment. The temperature will also be controlled by closing all doors and windows in the classroom, in order to maintain the room temperature and not disrupt the experiment.

Apparatus:
- Timer
- 1 sheet of squared paper (square’s area 1cm2)
- 1 non-heated lamp
- 1½ of a Petri dish
- 1 ruler
- 1 plastic spoon
- 5 Porcellio scaber

Method:
1. Collect the materials listed above. Next, plug-in the non-heated lamp and position it so that it is 19cm away from where the Porcellio scaber will be placed (measure this distance with a ruler). Then place the squared paper directly below the lamp and place the timer conveniently next to it. Then pick-up a plastic spoon and remove 5 Porcellio scaber from their

    * Biology Investigation 3.1 Porcellio Scaber (Slater, Woodlouse) Task 1 The crustacean Porcellio Scaber, or more commonly known as the woodlouse, is a species usually found in leaf litter or in fallen trees and bark. It feeds on detritus like many other isopods of its type, and is generally predated on by small mammals, lizards and some insects. The woodlouse habitat reflects its need to avoid warm and dry areas. The woodlouse is prone to desiccation (drying out) due to its body’s large surface…

    fourteen jointed limbs. Woodlice form the suborderOniscidea within the order Isopoda, with over 3,000 known species. The woodlouse has a shell-like exoskeleton, which it must progressively shed as it grows. The moult takes place in two stages; the back half is lost first, followed two or three days later by the front. This method of moulting is different from that of most arthropods, which shed their cuticle in a single process. Metabolic rate is temperature-dependent in woodlice. In contrast to mammals…

    nvestigation into the Factor of Light and Dark Affecting Woodlice Predictions It was expected that a woodlice would prefer a damp, dark, but moderately warm surrounding. Normally one would expect to find slaters under logs or concrete slabs in one's garden. Under these large objects, the sun cannot reach directly; therefore it is darker, damper and colder than the surroundings. Nevertheless, in winter we do not see woodlice crawling around very often, and, also at night, it may…

    Woodlice Investigation Introduction: The ecological niche of the woodlice Porcellio scaber. The woodlouse Porcellio scaber is native to Europe but also commonly found in New Zealand. They live in cool, dark, damp microhabitats such as in rotting wood, under rocks, in caves and leaf litter. Small insectivorous rodents and birds as well as some spiders feed on woodlice. In the rotting log from which I gathered my specimens there were also millipedes, crickets, weta and spiders living. Woodlice…
