High School Lessons about Trichloroethylene
The chemical compound trichloroethylene is a chlorinated hydrocarbon commonly used as an industrial solvent. It is informally referred to as TCE, and sold under a variety of trade names. TCE is a clear non-flammable liquid with a sweet smell.
The TCE Contamination and Cleanup Curriculum (TCE CCC) were written from a constructivist perspective. Constructivist learning encourages students to develop their critical thinking skills by initiating their own inquiries of the topic to be learned based on their own prior knowledge. This is achieved through supportive guidance and hands-on problem solving that challenges them to construct their research and communication (oral and written) experiences in order to make logical and critical connections to the topic.
