Equipment you will need

Net: For catching small fish and tadpoles

Pooter: A device for sucking up small organisms from leaves or under stones where it is dry near the edge of the pond.

Meter Rule or tape measure : for measuring the size of the pond or the depth of the water

Notebook and pencil: to draw diagrams and write down what you see

Hand lens: To make more detailed observations

 

 

Extra apparatus for making more detailed measurements

Thermometer
: It may be useful to record the temperature of different parts of the water

Light meter: To measure the light intensity

Digital camera: Photographs can often tell you more things than a written description

 

 

 

How to keep safe

Keep away from the edge of the pond except where yoy are told it is safe.
