Group Work: Meet the Scientist Lesson Objective: Students will be able to give examples of how scientists can gain scientific knowledge without experimentation Groups will be assigned a scientist to read about. After you read about the different scientists, answer questions about them in the “Meet a Scientist” worksheet. Then each group will share with the class a summary of their scientist's work and the methods they use in solving problems. You can do this by creating a drawing or acting it out.
