These curriculum-aligned lesson plans make it easy to take part through planting activities and environmental learning. Join thousands of educators in fostering students’ connection to nature while making a real impact in your local environment. Register your school, grab the resources, and get growing.
Schools Tree Day occurs each year near the end of July, however these lessons offer so much more and can be used in the classroom any time of the year.
Our units on mindfulness and wellbeing are best used often throughout the year. They help to develop skills in focus, resilience, emotional intelligence, and control of body and emotions.

Each year thousands of schools across Australia take part in National Schools Tree Day by getting their hands dirty and planting a few. But why are trees so important for the environment anyway? Check out this video to see how other schools have been participating each year. For more information and research from the National Tree Day team, head over to the National Tree Day site.
The lessons have been developed in partnership with Planet Ark’s Schools Tree Day – the largest nature-care event in Australian schools. You and your children will join thousands of amazing educators and teachers in making a difference, fostering a child’s love of nature and creating positive environmental change. So, get growing! It only takes a minute to register for Schools Tree Day.
