THE ECOLOGICAL QUESTION:
Do fish predators experience feast and famine?
animal energetics, energy balance, trophic status, feeding strategies, predator prey relations
WHAT STUDENTS DO:
Students use a spreadsheet to examine the relationship between fish with empty stomachs and their food sources.
Using a spreadsheet to make a simple figure (less advanced students); sorting data and calculating simple statistics, such as mean and standard deviation (more advanced students).
Written interpretation of a figure, and/or written explanation of the analysis results for explaining the relationship between fish with empty stomachs and their food sources, figure from spreadsheet data, written explanation of mean/standard deviation, written analysis of the published paper.
