Blackwater pros and cons video

At the right time of year, good blackwater is nature’s gum-leaf tea and is huge boost for our rivers, creeks and fish. In the wrong conditions, blackwater can be toxic. Learn more with this video.

And to learn how environmental water releases can help minimise the impacts of blackwater watch this video.

The pH scale explained

A great explanation of the pH scale, acidity and alkalinity in relation to everyday objects.  Please note; alkaline substances are referred to as ‘bases’ in this video.

The acidity and alkalinity of substances are related to taste in the video – be clear with students that they should NOT be tasting anything that is not food.

What is environmental DNA (eDNA) ? video

This short video explains how eDNA can help us detect native and invasive species by providing evidence about what is or isn’t present in the environment – it’s like nature’s genetic fingerprint !  eDNA testing is innovative technology that enables the detection of species without having to see, hear or catch them.  eDNA offers an unprecedented opportunity for monitoring endangered and invasive species, as well as for biodiversity assessments.

Pesticide Watch

In 2024 some schools will value add to their monthly water quality monitoring by opting in to participate in Pesticide Watch, a nation-wide program run by Brady Hamilton at Deakin University helping communities identify pesticides in their local waterways through citizen-science.

Find out more about the program by watching this video, about the testing procedure by watching this video, about the sampling protocol in this guide or watching this webinar we recorded with Brady all about pesticides and the research project.

The 2023 results have been published in this summary report.

For pesticide teaching resources click here or to follow the project join the Pesticide Watch Facebook Page.  

You can contact Brady Hamilton from Deakin University directly; brady.hamilton@deakin.edu.au
