The experiment
Some slaters were spread over a tray that had some wet soil and some dry soil. Half the tray was covered by a thick piece of cloth. After half an hour all the slaters were in the corner marked X. |
Slater fact file:
-
Slaters (also called woodlice) are crustaceans.
-
Crustaceans usually live in water, but slaters live on land.
-
Unlike insects, they have primitive lungs and an exoskeleton that is not watertight. Therefore they can easily lose water from their bodies.
-
When exposed to the sun they dry out quickly.
-
They prefer to have both sides of their body in contact with another surface. Often they will clump together.
-
They eat dead plant matter, including rotting wood.
