Students will explore the principles of electrical circuits, motor mechanics, and fluid dynamics through the construction and operation of a dual-mode bubble machine. They will investigate how changing the bubble-blowing mechanism (continuous vs. controlled burst) affects output, volume, and consistency. This hands-on activity encourages problem-solving, iterative design, and data collection as learners test variables such as bubble solution concentration, fan speed, and aperture size. Additionally, students develop fine motor skills and an understanding of cause-and-effect relationships in a real-world context.
Designed for upper primary and lower secondary students (Years 3–8) in Science, Design and Technologies, and STEM elective subjects. The product is suitable for classroom demonstrations, group investigations, or individual STEM projects. It supports differentiated learning, with extension opportunities for students to modify the machine's design or integrate simple coding controls (see Coding Platform section).
This resource directly supports the Australian Curriculum: Science (Year 4–6 – investigating forces and energy, and the use of materials); Design and Technologies (Years 5–8 – designing, producing, and evaluating a functional product); and Digital Technologies (Years 5–8 – if using the optional coding feature to control motor or fan speed). It aligns with the STEM F–10 integrated approach, emphasising inquiry-based learning, creativity, and real-world problem-solving. Key content descriptors include: ACSSU076 (forces and motion), ACTDEK019 (designing solutions), ACTDIP017 (simple digital systems).
No coding required for basic operation. However, an optional extension module (sold separately) enables students to control the bubble machine using a block-based coding platform (e.g., Scratch or Micro:bit). This allows for programming the bubble output timing, fan speed, and motor activation, integrating the Digital Technologies curriculum and introducing computational thinking.
Requires a flat, stable surface with access to water-resistant covering (e.g., a plastic tray or newspaper). The machine operates on 4 x AA batteries (not included) and is best used in a well-ventilated area or outdoors. Recommended for groups of 2–4 students. No specialised tools or software needed; optional coding extension requires a compatible device (tablet or laptop) and a coding platform account. Estimated setup time: 10 minutes. Bubble solution is reusable and non-toxic.
