This activity uses the concept of natural selection to introduce the idea of formulating and testing scientific hypotheses. Through a focused discussion approach, the teacher provides information and allows students time to think, interact with peers, and propose explanations for observations described by the teacher. While working on this activity, students will be able to: identify questions that can be answered through scientific investigations, design and conduct a scientific investigation, and use appropriate tools and techniques to gather, analyze, and interpret data. They will also have an opportunity to develop descriptions, explanations, predictions, and models using evidence and think critically and logically to make relationships between evidence and explanations. This site contains all information and instructions to complete the activity.
