Ideal for grades 6-8, these experiments are designed to help students identify the fundamental currents that drive ocean and weather systems on our earth. After seeing the results of their initial experiment, students will experiment with how changes in global temperatures, due to global warming, may affect these currents.

Understand that currents are found both in air and water
Recognize how global temperatures can affect these currents
