Galvanic vs. Titanic?

Students study galvanic exchange and how it produces electric currents.  In this ocean lesson students predict what metals deteriorate in salt water. 

Students interpret the Earth's history from models.  In this investigative instructional activity students create sedimentary deposit models. 

Young scholars construct their own battery made of lemons. For this electrochemistry lesson, students explain why lemons conduct electricity. They perform a series of experiments to investigate its conductivity.

Students examine relationships and interactions between different types of water. They experiment with colored water of different temperature and salinity and discuss how the results relate to real ocean currents.
