Towers of the Lost City

Middle school marine scientists compare the pH change in distilled and saltwater as acetic acid is added one drop at a time. Then they compare the pH change in both when sodium hydroxide is added. This experiment demonstrates the buffering ability of sea water. They apply the results to the waters around the Lost City hydrothermal vents.

I love Lesson Planet because it connects me to great websites that have a wealth of information for myself and students. For example, I recently found two great history websites that have a huge amount of pictures--a great place for my foreign language students who need visual aids to comprehend American history. I love Lesson Planet because the lessons are often easy to adapt for a variety of learners.
