Treasure Chest Lesson Plan

Treasure Chest with Digital Lock Title of Lesson: Treasure Chest with Digital Lock Date: Fall 2025 Author's Name: Designer and Dr. David Burghardt Grade level: 7/8 Content or Subject Area's: Informed engineering design with computer science and computer control Duration of lesson: 6 days General Objectives: Students will design, construct and program a treasure chest with a digital lock system that requires a specific button sequence to activate a servo motor, integrating programming logic, mechanical motion conversion, and engineering design principles to create a secure storage system with automated opening mechanisms. Learning Outcomes: What knowledge, skills, and strategies do you expect students to gain? (1-4 stated outcomes) After completion of the lessons, students will be able to: (use action verbs) 1. Use the informed engineering design process 2. Apply mechanical engineering principles to convert rotational servo motion into linear motion for latch mechanisms while calculating optimal positioning and movement angles. 3. Program conditional logic using button input sequences and servo control to create a secure digital lock system with feedback mechanisms. 4. Design, construct, and test an automated locking system that combines physical construction, digital programming, and mechanical motion to solve security challenges.
