Core Skills Analysis
Science
- Casey identified producers, consumers, and decomposers, recognizing their roles in energy transfer within a food chain.
- Casey described how energy diminishes at each trophic level, illustrating the 10% energy transfer rule.
- Casey linked the specific organisms in the activity to real‑world ecosystems, explaining dependencies and potential impacts of removal.
- Casey used scientific vocabulary (e.g., autotroph, heterotroph, trophic level) accurately in oral or written explanations.
Tips
Encourage Casey to construct a three‑dimensional food web using recycled materials, then role‑play the flow of energy by passing a “sunlight” token from producers to top predators. Follow up with a simple experiment: grow fast‑germinating seeds under different light conditions to see how a change in primary production affects the whole chain. Have Casey keep a short observation journal, noting any surprising connections or gaps. Finally, challenge them to research a local ecosystem and predict how a new invasive species could alter its food chain, presenting findings in a poster or digital slideshow.
