Population Density in the Ghettos
Students make calculations of population density to recognize the stressful conditions experienced by European ghetto dwellers due to high population density and scarcity of resources.
Curated OER
Progression's Price
Students reflect upon their regional and national environments, analyze causes of environmental problems as well as their implications, and examine effects of population growth as they participate in "The Popcorn Game."
Curated OER
Population Growth
Students grow duckweed, observe what happens when an organism population is allowed to grow without predation or competition, view videos about invasive species, and develop a proposal for controlling the growth of an invasive species in...

People Are Like Peas in a Pod
Students experiment with pea pods to observe/appreciate the diversity of individuals within a population, and to explain of how dominant and recessive traits, genotypes, and phenotypes help produce variation in a population.
