Science

The primary goal of the science program at BB&N at all levels is to give students a systematic approach to scientific problem solving. This is accomplished through a laboratory-based discovery approach adopted with the belief that insights are best developed in an experimental setting. Laboratory skills emphasize the habit of objectivity in observation and accuracy in data gathering and recording. Identification and control of variables, manipulation and presentation of data, and evaluation of the validity of experiments are emphasized as appropriate to the grade level.

The department aims to instill in students an appreciation for science as an imaginative, often impassioned human endeavor. Students gain an understanding of the common atomic base yet the amazing diversity of both the natural and man-made environment. They also appreciate the principles that help to describe the interactions of matter and energy.

In the Middle School, the science program familiarizes students with laboratory science skills and emphasizes the importance of mastering the processes and vocabulary of science. Learning through hands-on experience, students develop their awareness and understanding of the basic concepts of science necessary to excel in higher-level science courses. With the teachers’ guidance, students learn to manage their own laboratory work, acquiring new lab skills and techniques while being exposed to new material. The Middle School program carefully prepares students to take on the challenges of the demanding Upper School courses.

Grade 7: In Science 7 students explore a variety of topics from physical and natural science, each of which culminates in a hands-on experience, whereby students are able to apply the skills and concepts learned. Throughout the year, skills that are emphasized include safe and proper conduct in the lab, detailed observation, accuracy and precision in measurement and data collection, identification of variables, and evaluating experimental results. Students typically work with partners or in teams in order to enhance cooperative learning and collaborative skills. The first unit serves as the foundation for the study of science in the Middle School. Students study measurements, the scientific method, and graphing. A highlight of the first quarter is the Rube Goldberg Challenge. In the Energy unit, students learn about different forms of energy and energy conservation, becoming experts on one form of energy and sharing their knowledge with their peers. Building on the concept of energy transfer put into practice in the Rube Goldberg Challenge, students learn about the physics of roller coasters and use computer-based motion sensors to collect data to better understand kinetic and potential energy. The study of structures reinforces the concept that changes in the shape and arrangement of material can affect a structure’s strength and its ability to resist the forces of compression and tension. Students apply these concepts as they study bridges, with the goal of designing and building a pasta bridge that holds a minimum of 15 newtons. In the final unit, various activities introduce students to Newton’s Laws of Motion and problem-solving using physical equations. For the culminating activity, students build and launch their own bottle rockets and conduct an experiment to test one aspect of rocket flight.

Grade 8: Science 8 is an introduction to chemistry. It is a lab-centered program in which the experiments are designed to further develop laboratory skills and techniques; more responsibility in lab management is given to the students, while at the same time experiments provide evidence for the chemical nature of our world. In addition to the topics found in a typical introductory chemistry course, such as atomic theory and structure, the periodic table, classification of matter, chemical bonding and reactions, and acids and bases, all eighth graders plan and conduct a science project of their own design and participate in the BB&N Eighth Grade Science Fair. The year’s study culminates with the Qualitative Analysis Activity, an independent activity designed to utilize skills and concepts acquired during the year. As in Science 7, students are introduced to various applications of technology.
