Students inquire how to stop an oil leak in a model of the BP oil leak in the Gulf by simulating the situation in a 10 gallon aquarium. Students generate potential solutions, which are then tested and redesigned. Students learn about natural factors involved in this real life situation and scenario including ocean depth, properties of…

Students will learn that Earth’s capacity to absorb and recycle water naturally can be altered by the actions of humans and technology. In this lesson students will learn that people and their actions can harm our drinking water supply. Students should get a clear understanding that what happens above the ground can potentially end up…
