Calling all frogs (F-Year 2)

This lesson plan explores the calls of local frogs and stages of their life cycle.

Many types of frogs living in Melbourne’s waterways can be identified by their distinctive calls. The diversity of frog species in a waterway is a good indicator of its ecological health. Learning to identify frog calls will help students understand which frogs are in their local area and the importance of frogs to the waterway. Students will also explore the different stages of a frog’s life cycle.

These activities use digital applications such as Melbourne Water’s Frog Census app 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 understand the biology and distribution of frog species in Melbourne. This information helps us to develop effective policy and management strategies to conserve and enhance these populations.

Activity 1: Listen to the music

Students listen to frog calls to understand that each type of frog sounds different. First, they will listen to a chorus of frog calls as they sound in nature and then to each frog call separately.

Activity 2: Frog call treasure hunt

Students learn to identify a variety of frog calls heard in your local area, by going on a treasure hunt to match pictures of frogs with their calls.

Activity 3: Growing and changing

Students build models to demonstrate the different stages in a frog’s life cycle.

Activity 4: Conducting a frog census in your backyard

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