Giant Student Version Ear
encourages hands-on investigation
Without sacrificing size or key detail this three-part replica exposes the entire length of the ear canal and Eustachian tube so that the soundwaves entering the ear can be easily traced and to demonstrate how air pressure on both sides of the eardrum is equalized. The hammer, anvil, transparent ear drum, and the labyrinth all lift out for hands-on study. Functions of the 18 hand-numbered primary features are explained in depth in the accompanying study guide.
Overall dimensions: 16x11x7 inches (41x28 x18 cm).
