7th Grade builds lime kiln for chemistry experiments


In 7th Grade, the students study chemistry through the lenses of combustion, acids and bases, and salts. These all come together in the final experiments of the four-week block: the lime kiln. Built, fired, and taken apart by the class, the lime kiln helps the students better understand the lime cycle. They took marble and seashells, fired them, and discovered that, due to the immense heat, these transformed into quicklime, a strong base and one that is used to make cement.


For an arts component, Grade 7 sketches the lime kiln as part of the chemistry block.


Grade 7's work on campus drew many curious friends. Here is Ms. Goodman answering the Buttercup Kindergarteners’ questions.
