I made these Sense of Smell Swatches and Sense of Touch Boards last year for a early years class I was teaching. They were used as part of our Five Senses Unit. They were a hit! The kids loved to feel and smell the different boards and swatches as it gave them hands-on tactile objects to explore and manipulate.
(Sense of touch) put different objects in balloons and have the children guess what each one is. Then, open them up to see what it is. (Tie with elastics so it is easier to open.) To further the lesson, make a chart of prediction and result.
