Make learning about the human heart exciting and interactive with the Pumping Heart Model! This transparent, realistically detailed model lets children see and understand how the heart pumps blood and works with the lungs for oxygen exchange. Using the hand pump, kids can simulate pulmonary circulation, watching how blood moves through the clearly labeled chambers, arteries, veins, and lungs. The set includes 10 packs of dye, allowing young learners to visualize blood flow in a hands-on way. Designed for ages 8 and up, this educational science kit is perfect for classroom demonstrations, homeschooling, or independent exploration. The included Activity Guide provides engaging experiments and lessons, making this a must-have learning tool for budding scientists and anatomy enthusiasts!
