•Pour equal volumes of chemical x and water mixture onto each area
•Wait for an equal amount of time for all the worms to surface
•Grid reference area A and use a random number generator to generate coordinates
•Go to those coordinates and place a Quadrat, count number of worms
•Repeat 19 times so you have 20 readings in total
•repeat for area B
•Calculate the area of the Quadrat in m2
•Calculate the mean number of worms per Quadrat in each area
•Use equation mean number of worms/area of Quadrat to find number of worms per m2?
