That sounds absolutely wonderful! I love the idea of turning scraps into something new and exciting. For paper‑mache volcanoes, we can use old cereal boxes, some glue, and a splash of color. For simple circuits, maybe we can use old batteries, wires, and tiny LED lights from broken gadgets. We could even set up a “recycle treasure hunt” where each child finds a piece of material to bring in. I’ll start sketching out a plan so we can set everything up next week—just let me know what materials you have handy!
