Exploration of big bones can be an engaging and educational experience for young children, sparking their curiosity about the natural world and fostering a deeper understanding of anatomy, history, and science. Children can take this easy-to-clean, weighed set outside for exploration with messy materials like dirt, mud, or water, or use inside during loose parts activities. A variety of lengths encourages the discovery of size relationships, counting, and patterning. Largest bones measure 15cm long.
