To prepare for this lesson, gather noise-making items and stand behind a bookshelf or wall, making sure the students can hear, but not see, you. Take turns making different noises like ringing a bell, clapping hands and snapping your fingers. Have the students try to identify what each noise is. At the end of the lesson, write on a piece of paper. Since there is little to no noise with this act, students will be unable to clearly tell what you are doing; this makes the point that without hearing, students must depend on other senses.
To illustrate a lesson on sight, students will describe an object using only their sense of sight. Take a leaf and have students describe the shape, texture and color using numbers and other adjectives, without ever touching the leaf. Describing things like texture without using the sense of touch may be harder than it sounds.
The senses of smell and taste can be isolated, but the two senses do work together. Gather some food and household items like a banana, strawberry, peanut butter, lemon, pickles, flowers, grass and soap. While each student takes a turn being blindfolded, have her guess what each item is by smelling, without looking or touching. While still blindfolded, have students taste only the edible items, first while plugging their noses, then without their noses plugged. Students should notice that food tastes stronger when they can also smell it.
While we can see with our eyes, hear with our ears, smell and taste with our nose and tongue, we can feel all over the body. Isolate this sense by placing several different objects into a paper bag. Ask the students to reach inside the bag and -- without taking an object out and looking at it -- identify what they have in their hands. When a guess is made, the student can take the object out and see if he is right. This child will then pass the bag to the next student and ask him to find an object that is either larger or smaller than the first object picked.
