Chlorine Chemistry

The goal of Building Block Chemistry is to introduce students to chemistry without tackling the whole periodic table at once.

Recognizing basic elements as building blocks is essential to the study of science. And looking closer at one element in particular—chlorine—can help ignite students' interest in chemistry. 

The following materials outline a two-day study of Building Block Chemistry using basic concepts and easy-to-find materials.
