In this activity, students will work in collaborative groups to develop an advertisement for a political candidate in support of one side of an issue - should we build low-cost housing on part of the land presently occupied by an estuary? Each group will decide which side they want to support - either for or against building the housing - and write an ad that will be run in a local paper, or that will be viewed on local TV, to support their argument.
In this lesson, students determine the particle size and composition of a sample of soil. Soil composition determines many characteristics of soils, such as infiltration rates (the rate at which water moves into a soil), percolation rates (how fast water moves through the soil), settling rates (how fast sediments sink to the bottom of a body of water), oxygen content, and the ability of the soil to support plant and animal life.
In this lesson, students complete water quality tests such as pH, dissolved oxygen, nitrates, phosphates, and salinity for a water sample. After following these activities, students should understand the purpose of these tests, know how to run accurate water quality tests, and see how these parameters relate to the quality of the water in an estuary.
In this lesson, students identify which factors in an environment are biotic or abiotic factors and evaluate their effect on other organisms living within the environment.
In this lesson, students understand how water moves through different types of soils.
In this lesson, students explain how and why the settling rates of particles varies with particle size.
In this lesson, students understand the interactions between organisms living in an environment, and how energy flows from one organism and trophic level to another.
In this lesson, students create a visual representation of a habitat. Students should be able to explain the biotic and abiotic factors in their habitat, how those factors affect the organisms they are displaying in their habitat, the flow of energy through their habitat, and the soil and water conditions in their habitat.
