STEM Lessons - Model Eliciting Activity
The focus of this MEA is oil spills and their effect on the environment. In this activity, students from a fictitious class are studying about the effects of an oil spill on marine ecosystems and have performed an experiment in which they were asked to try to rid a teaspoon of corn oil from a baking pan filled with two liters of water as thoroughly as possible in a limited timeframe and with limited resources. By examining, analyzing, and evaluating experimental data related to resource usage, disposal, and labor costs, students must face the tradeoffs that are involved in trying to preserve an ecosystem when time, money, and resources are limited.

How do coral reef conservationists balance the environmental needs of the reefs with locals who need the reefs to survive? Joshua Drew draws on the islands of Fiji and their exemplary system of protection, called "connectivity", which also keep the needs of fishermen in mind.

This lab simulation will allow you to explore how carbon circulates through the environment. Through data collection and analysis, you will experiment with the impact that humans are having on the cycling of carbon and make data based predictions on how these impacts may change environmental outcomes to the year 2100.
