High School Courses (Grades 9-12)
Why spend the summer in class? Students value the ability to delve deeply into one content area without other demands on their schedule. Summer School is open to the public.
Courses are designed for students from any school, entering grades 9 – 12. For-credit classes help students advance in a subject area or fulfill a graduation requirement in order to free up space in their school-year schedule. And rising juniors and seniors can get a jump on the college application process with classes for the SAT and college essay-writing. Prerequisites are required for some for-credit courses.

What do self-driving cars, Alexa, iPhone's face recognition technology, and ChatGPT have in common? They are driven by modern advances in artificial intelligence. Whether you’re interested in law, healthcare, art, or economics, AI is poised to transform every discipline and industry in the future. AI is already all around us today, and by the end of the program, students will understand the underlying concepts and motivations behind technology such as computer vision, natural language processing, and neural networks.
Taught by instructors from Inspirit AI, this course will explore the foundations of machine learning and explore different applications of machine learning models. In the first half of the course, students learn AI’s core technologies including applications, foundational concepts, and programming tools through live lectures and coding labs. Students will not only learn about different types of machine learning models, but also apply those models to real data sets. In the second half of the course, students will complete an instructor-led group project applying AI to the discipline of their choice (e.g., music, healthcare, astrophysics, finance, etc.), utilizing the programming skills they developed in the first half. Students will also have the option the second week of this course of working on a team developing an in-house AI platform for use at Lakeside. You can read more about the curriculum, projects, and teaching team here.

This is a for-credit, grade-earning class. The High School For-Credit course application is required for non-Lakeside students.
This course is open to all students with little or no programming experience who want to go beyond just using computer applications. Intro to Computer Science is an introduction to how computers work and how to write software. Technical expertise or prior programming experience is not required, only an open mind and a willingness to experiment, explore, and have some serious fun. Students will learn some basics of programming in the Python language by writing a series of programs defined by their instructor. They will then have the opportunity to follow their own interests and pursue more complex projects that may require them to learn new, more advanced programming techniques. Quizzes will be used to check understanding of basic programming concepts, but the majority of the grade will be determined by successful completion of teacher- and student-defined projects. This course is designed as an introductory experience for students who are curious about computers and programming, but who have limited or no formal training.

Why read a play when you can experience it? In this immersive summer course, students will explore the voices of classic and contemporary playwrights, using their analytical skills to close read plays and the works that inspired them. Throughout the course, students will read, perform, and analyze a selection of drama and relevant texts, exploring how theatre reflects and reshapes the world around us. They will engage in lively discussions, scene workshops, and creative projects that deepen their understanding of performance, interpretation, and design. Assessments may include a play review, a close reading of a scene, a set design, and a monologue. In the second week of this course, students will travel on a three-night field trip to the Oregon Shakespeare Festival to see the works read in class come alive on the stage. The works students study will depend on Oregon Shakespeare Festival Programming and may include such playwrights and authors as Jane Austen, Keiko Green, Kate Hamill, David Hein, Irene Sankoff, William Shakespeare. Through our experiential study of these works, we will explore how theatre responds to issues of identity, race, gender, history, and justice—and how directors, actors, and designers bring those texts into dynamic conversation with contemporary audiences.

This course covers—and extends upon—traditional geometry topics including coordinate geometry, Euclidean geometry (triangle congruence and similarity and related proofs), trigonometry, and areas and volumes in two and three dimensions. Students are expected to have prior familiarity with many of these concepts from earlier coursework. Building on that foundation, the class deepens conceptual understanding through an emphasis on reasoning and sense making. The central goal is for students to develop an intuitive grasp of every concept, procedure, and equation. Traditional geometry serves as a framework for connecting mathematical procedures and problem-solving strategies to spatial intuition. In addition, the course includes an integrated introduction to programming in Python. Computer science concepts reinforce geometric thinking while fostering logical and structured reasoning skills. Topics include expressions, variables, conditional statements, functions and loops. The programming component of the class provides a sufficient foundation for motivated students to find success in AP-level computer science classes. No prior coding experience is required. Note: For Lakeside students, this course counts as M310: Accelerated Geometry II with Programming.

Service Learning Experience: Food Insecurity in Seattle
$455
6/22-6/26
8:30 a.m. - 3:30 p.m.
In this course, we start with the premise that access to culturally relevant and nutritious food is a basic right. Why doesn't everyone have this, and what can we do about it? This week-long course takes on these questions as a serious inquiry in which we expect to clarify a multitude of answers. Each day, we will work with a different organization and community in Seattle, offering our labor in exchange for knowledge and insight into the causes of and solutions to the problems of food insecurity. We will map the unseen factors in this complex phenomenon and build historical context to better understand why direct food support is in such high demand all around us. Through daily discussions we will also develop insights into the many forms "service" can take--from the volunteering we will do during this week to the career paths that lead individuals to make lasting, positive change.
If you want to gain deeper insight into the issues surrounding food insecurity, while also making friends, completing service hours, and getting to know different communities in and around the Seattle area, then this is the course for you!
This is an ungraded course earning no credit, but 20 service hours may be applied to graduation requirements (check with your school).

How should we preserve and curate the stories and experiences of the past to make them accessible and help promote deeper understanding that serves the communities of our region? This service learning course takes place in collaboration with HistoryLink.org: the free online encyclopedia of Washington state history, where students will support HistoryLink’s efforts to archive, curate, and publish new and updated material that expands people’s access to Seattle’s story via their various online platforms. The nature of the work students undertake might range from traditional historical writing to creating short videos or social media posts based on archival material and place-based history, or collecting peoples’ stories and experiences. Much of the time, the cohort will work from HistoryLink’s offices in historic Pike Place Market, and students might also visit different neighborhoods to work in the Seattle Municipal Archives or the Seattle Room at the Central Branch of the Seattle Public Library. Seattle is beautiful in the summer. What better time to take in all that the city has to offer?
This is an ungraded course earning no credit, but 20 service hours may be applied to graduation requirements (check with your school).
