Freshwater Detectives™ kit

Use the Freshwater Detectives™ kit to run your own water quality lesson

We have created a DIY water sampling kit for schools called Freshwater Detectives™. The kit allows teachers to prepare students for a freshwater sampling field trip in their local area.


The first of two short videos will guide the teacher with the aid of the classroom kit through:

  • How streams become polluted
  • Which bugs (macroinvertebrates) can be found in streams, what they look like and what their presence can tell you about the quality of the water
  • How to test for turbidity, pH, nitrate and oxygen
  • How to make a water scoop

The second video will show teachers and students alike what to do on the field trip, how to test water and how to interpret the results using the results poster and explanation sheets.

The programme is flexible. It can be run over a single day or over a whole term divided into nine weekly sessions

We have designed the kit for New Zealand schools and it is related to levels 2-4 of the science curriculum.

To order your kit please send your name and details to [email protected]

Your kit will be available for collection from our head office, level 3, 73 Remuera Road, Newmarket from 28 January 2019, or you can arrange for a courier to deliver it to your school. 

Each kit costs $300 including GST, which includes the classroom kit, field trip kit and posters and can be used with one or two classes.

Details of where to buy replacement items are inside the lid of the boxes so these kits can be managed by schools after purchase.
