What is the ecological impact that humans have upon our fragile environment? This PowerPoint lesson is designed to teach students about the human behaviors that have consequences for our planet, such as the burning of fossil fuels, overfishing, the clear
Ecology Lab: The Wild Bean Population - A Simulation of Populations. Population biologists have developed several methods for sampling a population. In this lab, you will use the sampling technique known as the "mark and recapture method" to estimate the size of a population of wild beans! Students will compare their estimation of the population size obtained from lab data to the actual population size and calculate a percent error.
