An investigation student can, with a help of others, re-formulate questions, so as they are possible dealing with characteristics of woodlouse biology, to evaluate the planning abilities, i used as a tool, a rubric (see below) with besides the basic parameters of the woodlice biology (food preferences, humidity, light intensity. A series of slides designed to take students through the woodlice 'choice chamber&' investigation. Through investigation, students uncover the important links between their personal observations and scientific ideas “in the best schools visited, teachers ensured that pupils understood the ‘big ideas’ of example, students taking biology may also be taking physics and find themselves confronted with contradictory rules and guidance. The woodlice are left on their own for a while, and then the number of animals in each quarter is counted woodlice prefer dark and damp conditions.
Woodlice are easy to find, easy to catch, easy to handle and easy to keep (in a covered bowl of damp paper, leaves and vegetable peelings) they should be used more i believe that they have the potential to become the white rats of school biology and psychology.

After 10 minutes, the proportion of aggregated woodlice under the “winning” shelter slightly increased to stabilize at nearly 80% of woodlice for 40, 60 and 80 woodlice experiments and around 70% with 100 woodlice set-up at the end of the experiments (fig 3.
Using a choice chamber to investigate animal responses to stimuli the purpose of this activity is to investigate how woodlice respond to stimuli, in this case: light invertebrates (organisms without a backbone) are easy organisms to observe as they. 1 the effects of insolation and evaporation upon the internal temperature of the woodlice, ligia oceanica, oniscus asellus, porcellio scaber and armadillidium vulgare, and of the cockroach, blatta orientalis, were investigated 2 during insolation, the temperature of a thoroughly dry ligia remains.

Typical experiments involving woodlice have combinations of light, dark, dry and damp areas we would expect to see more woodlice in the dark and damp sections of the choice chamber.
The common woodlouse (oniscus asellus) is one of the commonest and widely spread of the british woodlice woodlice are not insects, but are crustaceans more closely related to crabs and shrimps than insects the body is divided into three main regions, the head, the thorax (known in woodlice as the 'pereion'), and the abdomen ('pleon') the common woodlouse is typically grey with irregular. Woodlice can withstand higher ambient temperatures, for short exposures, in air at 50% rh than in saturated air, and this is the result of rapid transpiration in the field transpiration plays a significant part in determining body temperature, and may be of survival value during exposure to direct insolation. Biology investigation 31 porcellio scaber (slater, woodlouse) task 1 the crustacean porcellio scaber, or more commonly known as the woodlouse, is a.

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 the living organism that we chose to study were woodlice.

Biology investigation: woodlice other responses shown include a positive thigmokinetic behavioural reaction a woodlouse’s rate of movement will decrease in regards to how much of its body is in contact with another object.
Hi, i'm doing an invistigation on woodlice in biology i'm doing my experiement on the effect temperature has on the movement on woodlice, however i am stuck on trying to think of a way to be able to measure the movement of the woodlice once they have been in the different conditions. Woodlice habitats this lesson is designed to exemplify an argumentation approach to practical work, using a ‘predict, observe, explain’ framework students make observations about the places where woodlice are usually found and use this evidence to evaluate various claims about woodlouse behaviour.
Class practical this investigation is concerned with a causal explanation of the behaviour shown by woodlice in a maze at some points the animals must make a. 1set up choice chamber, placing and numbering a filter paper in each chamber 2set up the video camera to focus directly on the chambers 3using the tweezers, place the woodlice. When woodlice or maggots are introduced into the centre of the choice chamber, they will move towards and into the section they prefer by counting the number of animals in each section after a given amount of time, students can deduce the preferred conditions for a particular species.
