Science Education Against Drug Abuse Partnership (SEADAP)

Created by : 
Lewis Katz School of Medicine, Temple University

This program, designed for use in the science classroom, uses the aquatic flatworm (planarian) to teach students how drugs work in the brain to produce addiction. Because planarians have neurotransmitter systems that are similar to that of mammalians, they are ideal for using in inquiry-based lessons to teach students how the brain can be impacted by drugs. In these lessons, students have the opportunity to conduct experiments designed to help them discover the impact of caffeine, nicotine, and alcohol on the functioning of neurons and the brain. The lessons include a teacher’s guide with detailed instructions for the experiments, as well as questions for the students to consider after they have conducted the experiments and a Scientific Method Recap.
