Investigation Into the Conditions that Wood Lice Prefer

I am going to place twenty wood lice in the centre of a choice chamber

with four chambers around it. The four chambers will be dark and damp,

dark and dry, light and damp or light and dry. I am going to place the

dish in a dark place with a light shinning on it to simulate 24 hours

of sunlight. The bulb will be 40 watts and 60 cm away from the dish as

not to heat the dish. I will make two of the chambers dark by covering

them in card so no light will get through. There will be a piece of

cotton wool in each chamber. Two will be damp and two will be dry.

Cotton wool is vegetable matter as it comes from a plant. Since wood

lice eat this and they can also smell it which will attract them to

it's preferred condition.

I will make it a fair test by having all variables such as heat and

light constant by leaving it in a dark cupboard so it is not

interfered by day and night. I will also make it fair by leaving it

alone or the full 24 hours then record data.

I predict that the woodlice will prefer the dark and damp chamber

because woodlice associate darkness with safety and protection. This

is why woodlice live under such thing as stones because predators find

it difficult to locate and get at them. They also like moisture

because they are crustaceans and most other crustaceans live in water

such as crabs.

I am also using 6 sets of results, one from each group in my class. I

will then average out the data to account for anomalies.
