Canterbury Environmental Education Centre - Virtual Pond Dip II Pond Investigation Click here for teachers notes.
Lets carry out an investigation.
It must be a fair test. Using a net, make four sweeps of the same length close to the water plants. Put a little pond water in the tray and empty the net into it. Try the sweep again, but this time in the open water away from the pond plants. Sort out the animals, catching the large ones with with a white spoon and the small ones with a pipette.
