In our STEAM technology class, students explored how smart devices and Wi-Fi controllers work together through voice commands and simple engineering concepts. The lesson introduced students to controller boards with built-in Wi-Fi chips and how devices like Alexa can communicate with motors and lights. Students learned: How Wi-Fi-enabled controller boards send and receive signals Basic concepts of positive/negative power connections and motor control How smart home systems such as Alexa can...

The Experiment: Spin Art and Centripetal Force In this activity, students place a paper disc on a rotating platform (like a salad spinner or a motorized motor). As the disc spins rapidly, they hold markers against the paper. The Scientific Concepts Centripetal Force: When the disc spins, the friction between the marker tip and the paper, combined with the rotation, pulls the ink outward or holds it in a circular path. Rotational Motion: Because the disc is moving at a high speed, a single...

Project Overview: In this creative engineering lesson, students constructed a butterfly that can "flap" its wings. By pulling a wire mechanism at the back, the stationary butterfly comes to life, demonstrating the graceful movement of nature through simple mechanics. ⚙️ Scientific Principles 1.The wire functions as a connecting rod. When the student pulls the wire, it creates a "pivot" effect, converting a linear pull into a rotational movement of the wings. This is the basic principle behind...
