![]() ![]() Table 6.1 shows the standards for inquiry. Students at all grade levels and in every domain of science should have the opportunity to use scientific inquiry and develop the ability to think and act in ways associated with inquiry, including asking questions, planning and conducting investigations, using appropriate tools and techniques to gather data, thinking critically and logically about relationships between evidence and explanations, constructing and analyzing alternative explanations, and communicating scientific arguments. The standards on inquiry highlight the ability to conduct inquiry and develop understanding about scientific inquiry. Science as inquiry is basic to science education and a controlling principle in the ultimate organization and selection of students' activities. Multidisciplinary perspectives also increase from the subject-matter standards to the standard on the history and nature of science, providing many opportunities for integrated approaches to science teaching.Ībilities necessary to do scientific inquiry Students need solid knowledge and understanding in physical, life, and earth and space science if they are to apply science. The personal and social aspects of science are emphasized increasingly in the progression from science as inquiry standards to the history and nature of science standards. Students' understandings and abilities are grounded in the experience of inquiry, and inquiry is the foundation for the development of understandings and abilities of the other content standards. The sequence of the seven grade-level content standards is not arbitrary: Each standard subsumes the knowledge and skills of other standards. References for additional reading for all the content standards are presented at the end of Chapter 6. Those clusters were selected based on a combination of factors, including cognitive development theory, the classroom experience of teachers, organization of schools, and the frameworks of other disciplinary-based standards. The next seven categories are clustered for grades K-4, 5-8, and 9-12. The standard for unifying concepts and processes is presented for grades K-12, because the understanding and abilities associated with major conceptual and procedural schemes need to be developed over an entire education, and the unifying concepts and processes transcend disciplinary boundaries. Science in personal and social perspectives. Unifying concepts and processes in science. Note: A support stand is required and available separately.The eight categories of content standards are This economically designed apparatus is easy to set up.Ĭoncepts: Acceleration due to gravity, torque, rotational acceleration, center of mass. The support rod is swiftly pulled out, the ball and stick fall simultaneously, resulting in the ball landing in the cup! Did the stick really fall faster than the free-falling ball? After students study the apparatus they will recognize that the stick does not actually “free fall.” The stick rotates as it falls because of the hinge, and this causes the end of the stick to accelerate faster than its center of mass, allowing the end of the stick to beat the ball to the ground. A ball is placed on the end of the stick so that the ball is below the lip of the cup. A stick with a cup near one end and a hinge at the other is propped at an angle with a support rod. ![]() ![]() ![]() In the blink of an eye, illustrate important concepts, such as torque, acceleration and center of mass with this discrepant event demonstration. ![]()
