What if?
Exploring your senses What you need: Blindfolds What to do: 1 With a partner, explore how the senses of touch, hearing and smell can be used to navigate around a room without the use of sight. 2 Ensure all small or potentially hazardous obstacles are removed from around the room. Decide with your partner the path that the blindfolded student is required to take around the room. 3 Take turns being blindfolded and navigating the room, with your partner walking with you to ensure your safe navigation and providing assistance if needed. What if? » What if you wore earmuffs as well as the blindfold? » What if you blocked your nose?
» What if you were barefoot? No part of this publication may be reproduced, stored in a retrieval system or transmitted in any form or by any means.
