In this activity (page 59 of the PDF), learners spin and observe false eyelashes in jars of water (prepared at least 1 day ahead of time) to investigate the effects of different types of motion on the hairs suspended in fluid in the inner ear. The model also demonstrates how the vestibular system maintains or restores equilibrium despite movement. The lesson guide, part of NASA's "The Brain in Space: A Teacher's Guide with Activities for Neuroscience," includes background information, evaluation strategies and handouts.
