Secondary 3 – Physics: Student Projects about Electric Circuits
Secondary 3 students conducted a physics project on electric circuits using a creative approach. Instead of working with wires and bulbs on a flat board, they built a miniature house and wired it with both series and parallel circuits.
First, the students divided into small groups and began constructing or decorating houses using cardboard, glue, and other recycled materials. Once the basic framework was complete, they planned the electrical system inside the model. In some parts of the house, they installed bulbs connected in series, where the electric current had only one path to flow. In other rooms, they designed parallel circuits, allowing each bulb to function independently.
To bring the circuits to life, the students connected wires to batteries and added switches for control. When they turned on the power, they noticed key differences between the two types of circuits. In the series circuits, if one bulb went out, the rest stopped working, just like old-fashioned holiday lights. In the parallel circuits, however, one bulb could go out while the others stayed lit, demonstrating how electricity can be distributed more efficiently in a home.
This project helped students visualise how electricity flows through different circuit configurations. By building something hands on and practical, they gained a deeper understanding of how homes and devices are wired in real life. At the end of the project, each group presented their miniature house to the class, explaining how the circuits were arranged, what challenges they faced, and what they discovered. The activity not only made abstract concepts more concrete but also encouraged teamwork, creativity and communication which are key skills for future engineers or scientists. ***
