1. The physical optics experiment set helps children understand physical optics deeply and makes learning easier. 2. The 3way linear light source can be adjusted to control the direction of the light. 3. Lens material: plastic material, safe, durable and practical educational tool kit 4. Optical experiments: light refraction, convex lens refraction, lens refracture, prism refracture, etc Benefits and features Key benefits: promotes handson learning of optical concepts, supports clear understanding of refraction and lens behavior, and makes complex topics approachable for young learners. What makes it stand out: the 3way linear light source offers adjustable light direction, and the kit uses safe, durable plastic for the lens material while covering multiple optical phenomena through practical experiments. Important attributes: function includes a compact educational toolkit for optical experiments; material is plastic for safety and durability; performance enables observing light refraction, convex lens behavior, and prism effects in a controlled way. Use scenarios At home: children perform guided optics experiments to reinforce concepts learned in lessons and build curiosity through handson exploration. In the classroom: demonstrations and studentled experiments to illustrate refraction, lens behavior, and prism effects with reusable parts. Science fair preparation: develop and present practical optics demonstrations that showcase understanding of light pathways and lens/plastic interactions.
