Understanding the Scientific Method: Inquiry, Hypothesis, & Experimentation in Science

This educational resource guides students through the essential features of scientific inquiry. It covers key elements of the scientific method, including identifying problems, formulating a hypothesis, conducting experiments, analyzing results, and drawing conclusions. Emphasizing the importance of variables and controlled experiments, it prompts students to reflect on their learning experiences and consider how they can improve their scientific investigation skills. This reflection on past performance encourages a proactive approach to meeting scientific standards and expectations.
