Core Skills Analysis
Science
- Audrey showed an understanding of how gills function by designing a model experiment to demonstrate how water moves through a filtering system.
- Audrey connected a real-life biological idea to a hands-on investigation by using water, coffee, and a coffee filter as a simple analogy for gill action.
- Audrey practiced scientific inquiry by identifying an aim, planning a method, and recording results, which are key parts of an experiment.
- Audrey demonstrated cause-and-effect thinking by observing how the filter separated materials and using that observation to explain a scientific process.
English / Writing
- Audrey used formal scientific writing features by including an aim, method, and results, showing awareness of how experiments are communicated clearly.
- Audrey organized information in a logical sequence, which helps readers understand what was tested and what happened.
- Audrey practiced concise explanatory writing by focusing on the essential parts of the investigation rather than storytelling.
- Audrey’s written structure suggests she is learning how to use subject-specific language to explain an experiment in a clear and purposeful way.
Tips
Audrey could deepen this learning by comparing her coffee-filter model with a simple diagram of real gills, helping her see both the similarities and the limits of the model. She could also repeat the experiment with different filter materials to explore how structure affects filtering, then record observations in a table. A next step might be to write a short conclusion explaining what the model shows about gills and what it does not show. For a creative extension, Audrey could draw and label the experiment setup or create a step-by-step poster that explains the investigation to another student.
