Water everywhere!

The Year 4 "Oakstead" team went to Beaulieu and did pond dipping and a stream study. We also went to the Countryside Education Centre's new tree house.

It rained all day and we got very wet, but we had a great time! Thanks to all the adults who helped!

Pond Dipping:

First we filled the tray with water from the river and the ice cube tray.
(It had to be water from the river because that's what the creatures live in.)
Next we had to dip the net into the river, move it around in a figure of 8 and then pull it out.
Then we tipped the net upside down on the tray.
After that we had to wait until everything in the water settled.
Finally, we put the creature we found into the ice cube tray, so that we could study it.

We found a water louse, a dragonfly nymph and pond snails!



Stream Study:

We wanted to test how fast the river was flowing and how deep it was. We used two long sticks, one metre stick, a cork, a stopwatch and a tape measure.

To test how deep the river was:
We first put the two long sticks on each side of the river. We then wrapped the tape measure around the sticks. We tested the depth of the water at various points across the stream.

To test how fast the stream was flowing:
We put the cork on the same line as the first stick. We timed how long the cork took to travel 1 metre. The stream was travelling at about 1m every 6 seconds.
