LED Material Tests: Fun Science for Kids Try this screen-free experiment with your child using an LED light source! Test how different materials block or let light pass through. Try plastic, colored bottle caps, or cardboard with various thicknesses. Does fabric allow light? What happens when you make Play-Doh really thin? Light up a balloon and see how many layers of toilet paper it takes to hide the LED glow. This hands-on activity sparks curiosity and teaches kids about light and materials in a fun, interactive way. Perfect for rainy days or STEM learning at home, this activity encourages exploration and creativity while building problem-solving skills. A great bonding experience for parents and kids! #ledexperiments #stemforkids #sciencefun #handsonlearning #screenfreeactivities #learnthroughplay #diyforkids #funstemactivities #parentingtips #lightandmaterials #educationalfun #scienceforkids
