Life Cycle of a Frog Life Cycles – Activity 2 Lesson Focus Outcomes Life and Living 2.9 Compares and contrasts similarities and differences within and between groups of familiar living things. Indicators • Identifies changes during the life cycle of a frog. Skills Focus • Records • Observes • Shows responsibility and care • Collects data • Evaluates Background Information Collecting animals for observation should only be done if the animals are not harmed. In the case of this observation, a good supply of water and food will ensure the survival of the tadpoles. Once developed into frogs the animals should be released into the environment where they were found. There are numerous Internet web sites that explore the life cycle of a frog and provide detailed information on it. Before the Lesson Note: this lesson can be approached in two ways. (i) by collecting frogs eggs or tadpoles and observing their life cycle in class. (ii) by using only the worksheet to identify the life cycle of a frog. Materials Needed Frogs eggs or tadpoles, an aquarium or container for storing eggs/tadpoles, shallow water, rocks, water weed or pond weed, fish food (live from the pond or little pieces of hard-boiled eggs), a variety of resoures on the life cycle of a frog. Preparation • Ensure your container is prepared using water from the same environment the eggs/tadpoles were collected from. Keep the terrarium away from heaters and chalk dust. • Collect posters, books or charts to show the lifecycle of a frog. The Lesson Stimulus • The stimulus for this lesson could involve a field trip to collect frogs’ eggs or tadpoles. Alternatively the eggs/tadpoles could be collected prior to the lesson and introduced to the prepared enclosure at this time. Use collected resources on the frog life cycle to discuss with students. What to Do • Using the worksheet, show the students the change that is expected over the coming weeks as the tadpoles develop into frogs. • Frog observations should occur weekly. The students record development and compare changes from the previous week. • At each observation, students should identify the stage of development. After the Lesson Answers Teacher check Additional Activities • Identify frogs native to the local environment. • Use books and the Internet to identify unique and interesting frogs. Research the countries they live in. • Explore how frogs are seen as a key indicator to the stability and health of an environment/ecosystem. Display Ideas • Take photographs of the students collecting the frogs and tadpoles, and introducing them to their new environment. Display with appropriate captions. • Identify frogs from around the world. Display drawings and research about each frog around a world map. Use string to show the country where they can be found. ©R.I.C. Publications Low Resolution Images Display Copy 4 PRIMARY SCIENCE ~ R.I.C.

Life Cycles – Activity 2 Life Cycle of a Frog The tadpole has now developed into an adult frog and can move easily on land and water. The female frog lays eggs which are fertilised by the male frog. The tadpole continues to grow and starts to look like a frog with a tail. Frog Observations The tadpole hatches from the egg, breathing through gills. The tadpole develops legs and lungs.
