Learning objects Environmental evaluation project: frog pond habitat


Explore why a frog population is declining. Look at changes in the pond over time: water quality, habitat loss and predation by introduced species. Build a food web for the pond. Model population interactions. Identify which species have the greatest impact on the frog. Build a report using evidence you have collected to support your conclusions.

Educational details

Key learning objectives
  • Students investigate a wetland habitat and identify possible causes of the decline of a frog population.
  • Students construct and explore hypotheses about population dynamics in a wetland environment.
  • Students model relationships between a frog species and other organisms in a wetland environment.
  • Students identify primary and secondary consumers in a food chain and explore relationships between them.
  • Students explore the physical characteristics and feeding patterns of a range of animals that live in a wetland environment.
Educational value
  • Models how changes to an organism's habitat may cause its numbers to decline.
  • Uses visual comparisons, food webs, water quality analyses, population counters and a population change modelling tool to investigate changes in a frog pond habitat.
  • Requires students to choose between likely and unlikely hypotheses for frog population decline and test likely hypotheses scientifically.
  • Provides scaffolded feedback to both correct and incorrect student choices.
  • Includes detailed information and photo or video images for all species featured in the activity.
  • Includes a printable notebook which allows students to type in their observations and conclusions.
