Woodlouse Habitat Investigation
Amy and Imran’s class did an investigation to find out if woodlice
preferred dark or light conditions. Each group put 20 woodlice in their
dark/light/damp/dry box. They waited 20 minutes and then counted the
woodlice in each section. They recorded their results in a Carroll diagram.
Their teacher collected in all the results and worked out the average for
each section of the box.
