A knowledge of ecosystems and food webs is important in developing a greater understanding of our environment. Through observation and investigation of local ecosystems, students explore interactions between species. They infer the importance of food webs to all organisms and their own place in them. Students analyze human impacts on local ecosystems and propose and compare options in the recovery of damaged ecosystems. An extension could be for the students to return one week later and record any changes.
Students identify each organism as a producer, consumer, or decomposer.
Students imagine they are members of the town council of Buntsly, and they have to decide on the appropriate use of land just outside the city limits. Several interest groups have come forward with suggestions. They demonstrate their scientific skills and processes when they engage in simulation activities or apply their knowledge to analyze current issues. Skills and processes The teacher works with students to develop specific requirements and criteria for the simulation activity. These resources are those that have been evaluated since 1992.
