Automata Unit – 7th Grade Design & Engineering (Princeton Middle School)

This 3-week unit introduces 7th grade students to the world of automata through a structured progression of scaffolded activities that emphasize creativity, engineering design, and hands-on problem-solving.

Week 1: Introduction to Automata (Days 1-3)

To start, students are introduced to the concept of automata and the idea of transfer of motion. They explore the roles of cams, followers, and other simple mechanisms through visuals, discussions, and physical models.
Students build template-based paper automata, allowing them to focus on understanding how mechanisms work without the added pressure of designing from scratch. This activity builds a strong foundation and eases them into the more complex design challenges ahead.

Week 2: Planning & Preparation (Days 4-9)

In the second phase of the unit, students begin planning their final foam-core automaton projects. They brainstorm original ideas that reflect a chosen theme, sketch blueprints on graph paper, and learn how to prepare files for laser cutting using vector-based design software.
Students have creative freedom in both the aesthetic and mechanical aspects of their designs and are encouraged to make purposeful choices based on personal interests or design constraints.

Week 3: Building & Presenting (Days 10-15)

Once students had their plans finalized and materials ready, they transitioned to building their automata. Using tools like X-Acto knives, hot glue guns, coping saws, and drill press, they cut, colored, assembled, and troubleshoot their designs. The unit culminates in "Shark Tank"-style presentations, where students pitch their finished automata to classmates and visiting peers. They also reflect on the design process, the challenges they faced, and how they overcame them.
