Key benefits Experiments: supports a range of imaging experiments and standard optical procedures, enabling handson exploration of optics concepts. Educational value: helps learners understand the reflection and refraction of light and fosters interest in physics and science. Classroom ready: designed for use in middle and school physics laboratories; suitable for standard lab setups. Fivepiece optical set: includes a triangular concave lens and a concave lens as part of a fivepiece kit, offering multiple options for experiments. Use scenarios Inclass demonstration: teacher uses the kit to illustrate light behavior, reflection, refraction, and image formation for clear, observable results. Studentled experiments: groups investigate lens properties such as focal length and magnification, forming and analyzing images. Lab project integration: combine with other optics equipment to complete a broader optics module and practical investigations.
