Core Skills Analysis
Science
- Casey showed understanding of how an ocean food chain works by identifying that living things in the sea depend on each other for food and survival.
- He learned about the transfer of energy from one organism to another, likely starting with a producer and moving through different consumers in the chain.
- The activity helped Casey practise sorting organisms into a sequence, which supports scientific thinking about predator-prey relationships and ecosystem connections.
- He also built vocabulary and conceptual understanding related to marine life, food sources, and how changes in one part of a food chain can affect the whole system.
Tips
To extend Casey’s learning, have him draw a full ocean food web instead of just one chain so he can see how multiple animals are connected. He could label each organism as a producer, consumer, or predator and explain what might happen if one species disappeared. A short research task on real ocean animals, or building a model with cards and arrows, would deepen his understanding of energy transfer and interdependence. For a hands-on challenge, he could compare an ocean food chain with a land food chain to notice similarities and differences in how ecosystems work.

Learning Standards
- SC1-WS (Working Scientifically): Casey’s activity involved asking how ocean organisms are connected and recognizing that this can be answered in different ways through observation and discussion.
- SC1-MAT (Everyday Materials): Not directly addressed in this activity.
- SC3-BIO (Biology: Cells and Organisation): Not directly addressed in this activity.
- SC3-PHY (Physics: Energy): Casey’s food chain work matches the idea of energy transfer between living things in a system, helping him understand how energy moves through organisms in an ecosystem.
