Core Skills Analysis
Science - Marine Biology
- Milly learned about the unique feeding mechanism of starfish, specifically their ability to evert their stomach outside their body to digest prey externally.
- She understood the role of digestive enzymes released by the stomach to break down prey outside the body before absorption.
- She identified the types of prey starfish commonly consume, such as shellfish like clams, mussels, and oysters, and the method starfish use to access this prey using suction-cupped feet.
- Milly practiced scientific communication skills by watching an educational video and sharing facts accurately during a conversation with another person.
Tips
Tips: To deepen Milly's understanding of starfish biology and marine ecosystems, encourage hands-on exploration such as creating a simple model of a starfish demonstrating stomach eversion and feeding. Visiting a local aquarium or tidal pool can provide real-life observations of starfish and their behaviors. Integrate creative writing by having Milly imagine and describe a day in the life of a starfish, focusing on feeding and survival strategies. Additionally, comparing starfish digestion with human digestion can highlight biological diversity and adaptation, helping solidify these concepts.
Book Recommendations

Learning Standards
- ACSSU072 - The growth and survival of animals are affected by the physical conditions of their environment: Understanding starfish feeding behavior shows adaptation to their marine environment.
- ACSSU074 - Living things have structural features and adaptations that help them to survive in their environment: Starfish stomach eversion is a unique structural adaptation.
- ACSHE050 - Communicate ideas, explanations and processes using scientific representations in a variety of ways: Milly sharing facts demonstrates this skill.
Try This Next
