Teacher Note: In this clip, Marie Sklodowska (not yet Curie) and Pierre Curieare at dinner with friends, and Marie uses grape fermentation as a model to describe radioactivity.
Distribute Handout One: Experimentation and Discovery Note Catcher and have students take notes on what they see.
Group discussion questions:
Ask the group to explain their understanding of radioactivity based on their investigations. The grape fermentation model in the clip is imperfect, as fermentation is a chemical reaction that changes a substance (sugar into alcohol), where radioactivity is a reaction that changes the element itself. Ask students to critically analyze the difference.
Ask students whether and how the Curies’ investigations mirrored their own.
