Meet the frogs (Years 3-4)

Growling Grass Frog

In this lesson plan, students will learn about the different species of frogs that live in the distinct ecosystems of Melbourne's waterways, and explore their life strategies to determine how they have evolved to survive in each habitat.

These activities use digital applications such as Melbourne Water’s Frog Census app and Google My Maps to develop students’ ICT skills. 

The Frog Census app is a powerful citizen science tool that enables students, their families and the wider community to contribute to understanding the biology and distribution of frog species in Melbourne. This information helps us develop effective policy and management strategies to conserve and enhance these populations.

Activity 1: What is alive?

Students distinguish between living and non-living things. They also discover what makes an animal a vertebrate or an invertebrate, and explore how vertebrates are grouped – focusing
on amphibians (frogs).

Activity 2: A frog’s life

Students explore the fact that every animal has a life cycle, and investigate the life cycle of a frog: from egg, to tadpole, to froglet, to frog. They explore how frogs' life cycle is related to growth and survival.

Activity 3: Know your frog

Students use Melbourne Water's Frog Census app to make predictions about why different life strategies assist frogs' survival, and appreciate the importance of good habitat for their survival. Students research one frog and present their information to the class. 

Activity 4: Frog census data mapping

Students practice using the Frog Census app to find frogs with an in-school simulation activity. They plot their findings on a hand-drawn map, then digitally using an app such as Google My Maps.

Activity 5: Conducting a frog census in our local area

In this evening excursion or at-home activity, students and their families have the opportunity to be citizen scientists: collecting meaningful and useful frog call data from local wetlands to support the Frog Census, an initiative managed by Melbourne Water.
