The war on weeds
Use this article to find out how students at Kaniere School are helping scientists combat the spread of weeds. They’re using simple digital technology to identify the weeds and upload the information to a national database, iNaturalist. The article shows how students can use digital technology to become citizen scientists and act locally on a national issue.

The project demonstrates how classifying involves both careful observation and comparison and the importance of data collection to both identify and monitor issues.
The article offers suggestions on how other schools can join the war on weeds. This supports the science capability ‘Engage with science’.
