Large lengthened base provides a wide, stable foundation for optical experiments, reducing wobble and enhancing safety during use. Very clear scale marks on the base and components enable precise alignment and measurement, helping students observe and compare results with confidence. quality workmanship and durable construction ensure reliable performance in busy middle school physics labs and over many classroom cycles. Designed for school optical experiments, this optical equipment set supports a range of classroom activities and demonstrations as part of the middle school science curriculum. The set features a stable, modular structure that maintains alignment during experiments, making it easier for students to focus on concepts and learning outcomes. Removable components and easy assembly and installation enable quick setup, flexible reconfiguration for different experiments, and minimal downtime between activities. Use scenarios Classroom demonstrations: teach basic optical principles such as reflection, refraction, and light paths with visible alignment and a steady setup. Student lab activities: small groups assemble and adjust optical paths, using the clear scale to measure and record observations. Homeschool or afterschool projects: modular design supports independent exploration and rapid reconfiguration for a variety of optical investigations.
