How Locks and Home Security Systems Work

How Locks and Home Security Systems Work is a free, self-paced learning path in Engineering & Robotics, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to trace the evolution of security devices; define the purpose of security systems; analyze material strength in lock design.
