What makes some internet videos more popular than others? Where do gender inequities pop up in the music industry? What are the demographics of police stops in the United States? Did you know that you can explore and analyze real-world questions like these using code? In this semester-long course, you will develop the skills to use the Python programming language to mine public datasets for interesting patterns and to statistically analyze and visualize those patterns using beautiful, code-generated graphs. You will then build upon these skills by learning how to create your own machine learning models that you can use to make predictions in fields of your choice, and even enter some of your models into competitions. You will come away with skills to critically analyze and evaluate trends in science, society, and culture with the goal of using code to dig deep into questions that you are interested in exploring. No previous coding experience is required, but students will be expected to take initiative in the process of researching and developing project topics, learning any extra skills required for the projects that they select, and tinkering with their codes to accomplish their goals. Enrollment in the first-semester course, 3D Models and Animations, will be useful but is not necessary for this second-semester course.

Are you interested in designing your own characters, animations, and games while also learning foundational skills in coding? In this semester-long, project-based course, you will create renderings of 3D models, physics-based animations, and user-interactive games using VPython, a coding environment that combines the Python programming language with a 3D graphics module. Through your projects, you will learn how to use coding elements such as variables, loops, lists, conditionals, functions, and more. We will use the engineering design process to develop each project, including research, brainstorming, iterative prototyping, peer feedback, and sharing. This is a highly collaborative class; you will share your codes with your classmates so that they can build upon them “open-source”-style, and you will adapt and cite some of the work of your classmates to move your own projects forward. No previous coding experience is required, but students should be comfortable with mathematical thinking, troubleshooting, and sometimes feeling confused! Since we will be drawing upon physics concepts to create animations, students should enter this course having completed a year of Physics 9 or equivalent.

The first half of the course will be directed at learning about female anatomy and physiology, growth and development, and reproduction. This part of the course will focus on female ontogeny, puberty, pregnancy, abortion, and contraceptives. The latter part of the course will deal with disease and aging, and the cross-section of women’s health in history, society, economy, politics, and culture. Here we will focus on gender identity, reproductive rights, social movements, representation, nutrition, and more. In both portions of the course, we will address ethical concerns for women that will range from the manipulation of embryos to healthcare access. Through labs and other major assignments, students will examine biological differences between men and women, develop an understanding of their own hormone cycle, and analyze societal expectations and pressures placed on women.
Why do some structures float while others sink? How do forces determine the motion of an object? Why do some processes absorb energy while others release it? In STEAM 8, students build on the investigative foundation of STEAM 7 while thinking more abstractly, designing controlled experiments, and communicating ideas with greater precision and independence. Topics are drawn from earth science, physical science, and life science, spiraling upward from the content and skills developed in STEAM 7. Throughout the year, students strengthen their ability to analyze data, refine procedures, and construct evidence-based explanations, communicating their findings through lab reports and research papers. The course culminates in a long-term engineering challenge: designing, building, testing, and refining a cardboard boat for passengers to race across the school pool. Applying principles of forces, buoyancy, and structural design, students engage in iterative prototyping and collaborative problem-solving before competing in a spirited final race. By the end of the year, students demonstrate growing technical fluency and independence as investigators and engineers, prepared to tackle increasingly complex problems with creativity, rigor, and confidence.
What makes a habitat healthy for living organisms? What causes natural disasters? How does energy shape the world around us? In STEAM 7, students investigate questions like these through hands-on, phenomenon-based learning. Integrating science, technology, engineering, art, and math, this course builds foundational skills in experimental design, troubleshooting, and scientific communication. Topics are drawn from Earth science, physical science, and life science, and the content and skills in this course spiral and deepen in STEAM 8. The centerpiece of the course is a semester-long ecological project in which students raise trout from eggs to fingerlings in the classroom. Along the way, students monitor water chemistry, analyze fish genetics, and investigate the environmental factors affecting aquatic life. Their work culminates in releasing the trout into the Farmington River. Students share their learning through lab reports, research papers, artistic representations, and short films. By the end of the year, they not only understand key scientific concepts but also see themselves as confident investigators and designers.
