Science At the Tukituki River

The class took part in five different experiments at the Tukituki River. They tested for the ph level, clarity, estimated the speed of an area of flow, measured the conductivity of water and temperature.  They will also be looking at plant and animal life within the river later in the week.

It was a full on experience with lots of hands on, willing to get wet feet and a general hesitance to leave as they did not have time to have a skimming stones competition.
