Learning benefits
- 💡 This activity introduces children to the physics of reflection and the law of reflection, which states that light bounces off a flat surface at the exact same angle it hits it. Measuring and cutting angles develops practical geometry skills and spatial awareness. Additionally, assembling the nested cardboard tubes fosters problem-solving and fine motor coordination.
Safety notes
- ⚠️ Adult supervision is required when cutting the thick cardboard cartons with scissors. If using real glass pocket mirrors instead of acrylic, ensure an adult handles the reflective tiles to prevent any accidental scrapes or cuts from sharp edges.
Cleanup
- 🧹 Gather all discarded cardboard scraps and carton tops and place them into the recycling bin. Peel any stray pieces of duct tape off the table surface and discard them in the trash. Store the scissors, ruler, and any leftover tape back in their designated craft bins.
