Year 4 Science

Australian Curriculum–Aligned Science Videos & Teaching Resources

Welcome to the Year 4 Science hub for Critter Quest Education — a growing collection of Australian Curriculum–aligned science videos, classroom resources, and learning materials designed to support Australian primary classrooms.

This Year 4 Science hub focuses on Australian Curriculum (ACARA) Biological Sciences and Earth and Space Sciences content descriptions, with a strong emphasis on ecosystems, habitats, food chains, producers, consumers, decomposers, and the water cycle. Resources are designed to support inquiry learning, classroom discussion, scientific vocabulary development, and engaging science exploration in Australian primary classrooms.

Each section is aligned to specific Australian Curriculum (ACARA) content descriptions to support structured Year 4 science teaching.

All resources are designed to be:

✅ Curriculum-linked
✅ Student-safe
✅ Classroom-friendly
✅ Short and engaging
✅ Easy to use for busy teachers

Browse Year 4 Science by Content Description

Resources are organised by Australian Curriculum (ACARA) content descriptions to help teachers quickly find curriculum-linked science materials for Year 4 classrooms.

Biological Sciences (AC9S4U01)

Food Chains | Producers, Consumers & Decomposers

Content Descriptor: 🔗 AC9S4U01

Explain the roles and interactions of consumers, producers and decomposers within a habitat and how food chains represent feeding relationships.

Achievement Standard

By the end of Year 4, students identify the roles of organisms in a habitat and construct food chains.

🌿 AC9S4U01: Food Chains | Producers, Consumers & Decomposers for Kids

Students explore ecosystems and food chains while investigating how producers, consumers, and decomposers interact within habitats.

Topics explored include:

  • food chains and feeding relationships
  • producers, consumers, and decomposers
  • herbivores, carnivores, and omnivores
  • predator and prey relationships
  • ecosystems and habitats
  • energy flow in ecosystems
  • food webs
  • photosynthesis and plant roles in ecosystems
  • decomposers and nutrient recycling

Designed to support:

  • understanding food chains and food webs
  • identifying organism roles within habitats
  • recognising feeding relationships in ecosystems
  • introducing ecosystem vocabulary
  • scientific vocabulary development
  • observation and inquiry skills
  • whole-class discussion and inquiry learning

📚 Classroom Resources Coming Soon (Biological Sciences)

Year 4 Biological Sciences classroom resources aligned with AC9S4U01 are currently in development.

Future resources will explore food chains, habitats, ecosystems, food webs, producers, consumers, decomposers, predator-prey relationships, and energy flow through curriculum-linked classroom activities and reading materials.

Earth and Space Sciences (AC9S4U02)

The Water Cycle | Evaporation, Condensation & Precipitation

Content Descriptor: 🔗 AC9S4U02

Identify sources of water and describe key processes in the water cycle, including movement of water through the sky, landscape and ocean; precipitation; evaporation; and condensation.

Achievement Standard

By the end of Year 4, students identify key processes in the water cycle and describe how water cycles through the environment.

🎥📚 Coming Soon (Earth and Space Sciences)

Year 4 Earth and Space Sciences videos and classroom resources aligned with AC9S4U02 are currently in development.

Future resources will explore evaporation, condensation, precipitation, cloud formation, sources of water, and movement of water through the environment using curriculum-linked science explanations and inquiry activities.
