Anatomy of Dehydration

In this engaging lesson, students take a look at the effects of dehydration and over hydration on the body and electrical conductivity of the heart. They will also learn about what electrolytes are, basic heart rhythms seen on an EKG and how the heart conducts electrical impulses. Also included is a review of necessary elements that the body needs, osmosis, and calculations that doctors use to determine the amount of IV fluids a child needs for dehydration. The learning doesn't stop there! There is also a lab for testing electrolyte solutions.
This hands-on lesson works well in connection with a cardiac unit.
