Case Study on Mark and Recapture
Estimating the population size of animals is an important task for wildlife biologists, who can use the data to assess the health of a population. It requires diligent observation skills coupled with the ability to use empirical models that effectively determine the number of animals based on field surveys. The most common method for estimating the population size of animals is mark and recapture....

Life Cycle Analysis and Assessment of Crop Production Methods
Students use their ecological knowledge of soil processes, energy, water systems, and human interactions to compare the environmental impact of food production. Each group of 3-4 students develop life cycle analyses (LCA) for a single crop grown under different scenarios. As individuals, students are responsible for developing two LCA for that crop, and then together in their groups, they compile...

Simulating Sampling Communities and Calculating Diversity Indices with Scrabble Game Tiles
Using tiles from a Scrabble game, we present methods to create simulations of sampling exercises and to develop diversity indices. The tiles represent species, and so a known sampling universe (100 tiles) allows comparing a sample with the known distribution of species. We then offer several variations to simulate different kinds of sampling (larger sample size, more samples), alter the rarity...

How the Bioblitz Boosts the Zoology Course
Collection of invertebrates on campus, as part of the BioBlitz, increases the interest in students in animals as they get to go out to the field and collect specimens. They also learn about collection techniques and equipment. These activities also provide an opportunity for experimental design. Students are also contributing to the species count of the BioBlitz.

Literature circles as active learning packets for use in the natural sciences: Transforming traditional supplemental instruction into guided study
At Paul Smith's College, we have worked to transform the model of weekly SI (supplemental instruction) into GSG (Guided Study) for General Ecology (Bio 210). We modified literature circle worksheets based off of the work of Harvey Daniels to be used in the natural sciences. We then created a step-by-step instructional framework to implement literature circles in the natural sciences. This...
