TOPIC III: ECOLOGY - Populations in an Ecosystem ESSENTIAL CONTENT OBJECTIVES INSTRUCTIONAL TOOLS Population Dynamics and Graphs (17.5) Type of Growth Exponential growth Logistic growth Factors Affecting Growth Birth rates and death rates Immigration and emigration Human population Age Population pyramids Patterns of growth Carrying Capacity (17.5) Limiting Factors (17.5) Density-Dependent Predation Competition Human Activity Density-Independent (17.4, 17.8) Seasonal Variations Catastrophic Events Natural Disasters Utilize data and information about population dynamics, abiotic factors, and/or biotic factors to explain and/or analyze a change in carrying capacity and its effect on population size in an ecosystem. Compare the different types of growth in a species population. Synthesize an original example of carrying capacity in an ecosystem. Investigate how natural disasters have affected population and life in Florida. Explain that science is one of the processes that can be used to inform decision making at the community, state, national, and international levels. Identify limiting factors and other population dynamics. (ALD) Describe and investigate various limiting factors in the local ecosystem and their impact on native populations, including food, shelter, water, space, disease, parasitism, predation, and nesting sites. Explain how political, social, and economic concerns can affect science, and vice versa.

Score/Step 5.0 I am able to analyze data and information about population dynamics and limiting factors to explain a change in carrying capacity, the effect of population size, or the distribution of species in various types of ecosystems. Design an experiment to test the effects of limiting factors on the growth of a sample population. (Examples of limiting factors can be either abiotic – temperature, nutrients or biotic – competition, predation, disease.) Score/Step 4.0 I am able to evaluate data and information about population dynamics and limiting factors to account for a change in carrying capacity, the effect of population size, or the distribution of species in various types of ecosystems. Evaluate given data from a population growth experiment to hypothesize the impact of limiting factors on the population size. (Examples of limiting factors can be either abiotic – temperature, nutrients or biotic – competition, predation, disease.) Score/Step 3.0 Target (Learning Goal) I am able to identify limiting factors and other population dynamics. Classify limiting factors as abiotic and biotic and predict their effect on population’s size. (Examples of limiting factors can be either abiotic – temperature, nutrients or biotic – competition, predation, disease.) Score/Step 2.0 I am able to identify that population change over time. Interpret a graph of a population’s growth over time. Score/Step 1.0 I am able to define a population. SC.912.L17.8: Recognize the consequences of the losses of biodiversity due to catastrophic events, climate changes, human activity, and the introduction of invasive, nonnative species. (Cognitive Complexity: Level 3: Strategic Thinking & Complex Reasoning) Scale Learning Progression Sample Progress Monitoring and Assessment Activities 5.0 I am able to predict positive and negative consequences that may result from a reduction in biodiversity. Analyze and synthesize information from scientific journals, local newspapers and other media sources to evaluate the impact of climate change on biodiversity. Score/Step 4.0 I am able to predict positive and/or negative consequences that may result from a reduction in biodiversity. Assess the impact of the loss of biodiversity as a result of events such as natural disasters (hurricanes, tornadoes, fires, and tsunamis), climate change and human activities (pollution, habitat fragmentation, invasive species).
