Lesson 3: How do drugs affect planarians?
This lesson is part of the unit:
In this lesson, students are tasked with investigating a popular energy drink and its components: caffeine, B vitamins, sugar, and ginseng. Students apply various combinations of the components, along with the actual energy drink, to planarians in order to test the behavioral effects of these substances on the planarians. Using hypothesis development, data collection, and analysis, the students draw conclusions regarding the effects of various drugs and combinations of drugs on planarians and how this might relate to humans. As an assessment, the students look at the nutrition facts of different popular beverages in order to compare the amounts of drugs in these drinks to that of the energy drink.
