Ice excavations are great fun for children of all ages. Younger children can pour warm water over the top or use a pipette and watch the ice melt, while older children can use syringes to measure how much water is needed to melt the ice or just use the scale to practice number recognition. It’s also a great exercise for learning about volume and capacity. We’ve been having great fun with our LEGO ice excavation recently.
