Pique a student's interest in the sense of touching by asking: What is the difference between hot and cold, large and small, smooth and rough? For one activity, place multiple objects of varying shape, area, temperature and mass into socks. Hand them around and have the students draw pictures of what they felt. Reveal the objects at the end. For another lesson, have the students place their hands on top of their head and place different objects in front of them. Ask them to describe each object without touching the objects.
Place a variety of aromatic foods into a bag and have the students attempt to guess the food. You can also blindfold the students and place the food in front of their noses. This lesson will allow students to appreciate identifying food without the aid of their sight or hands. Have the students taste the food to see if their two senses corroborate.
Give the students a variety of foods to taste, such as lemons (bitter), oranges (sweet) and salted pretzels (salt.) Cut these foods into small pieces and give them to the students one at a time. Ask them to place each type of food on different parts of their tongue. Generate feedback by asking if they can tell if different parts of the tongue taste different kinds of food.
Tell the students you'll randomly place an object inside the classroom. Have the children leave the classroom and then place the item on a desk or cabinet. Bring the students back in and reward the first to spot the object. You can also blindfold the students and ask them to sit down in a chair or perform a task. Ask students to reflect on the value of sight.
Test the different sounds of a variety of in-class objects, such as desks, tables books or hollow items by having them thump them like a drum or striking them with a pen or pencil. Construct a shoe-box guitar or plastic cup telephones to observe sound waves. Have the children gently hold their throat to observe the vibrations of their larynx. Group students into stompers and listeners. Have one group of students jump up and down on the floor with the other group keeping their ears to the ground, feeling and listening to the vibrations to help students understand how sound is transmitted.
