Have each student put on various pairs of colored glasses, and then ask them to identify the differences they see when they look through the various lenses. Have the students place sheets of colored cellophane sheets in different shapes on an overhead projector. Ask the children to identify the shape and color of each transparency.
Cut a hole in an enclosed cardboard box big enough for a child’s arm to reach inside. Inside the box, place a tennis ball, rock, feather, pen, small pine cone, piece of sandpaper, sock and marble. Have students reach inside and try to guess what they are feeling. When they are all done, remove the contents of the box and ask them to identify the shapes and colors of the items. Set up a small fan. Explain how the fan is a circle. Have each student stand in front of the fan with the breeze blowing in her face. Then wipe her face with a moist towelette, and ask how the breeze from the fan feels different. Set up a series of items that qualify as hard, soft, smooth and rough; for example, a stone, a piece of soft foam, a plate and a piece of tree bark. Have the students feel the items as you explain the meaning of hard, soft, smooth and rough. Then have them identify the color and shape of each item.
Have rectangular pieces of unsweetened chocolate, sugar cubes, lemon slices and salt for each student. Ask them to identify the colors of each item and the shape of the first three items. Have them draw a triangle in the salt, and then have them taste each one as you explain the terms “bitter, sweet, sour and salty.” Blindfold students and give them tastes of orange, apple, grape and peach. Ask them to identify which fruit they are tasting. Show them pictures of each fruit, pointing out the shapes and colors of each.
Record various everyday sounds such as a toilet flushing, sneeze, door closing and car starting. Play the recordings one at a time in class and ask the students to identify them. Show the students pictures of a toilet bowl, door and car. Discuss the shapes and colors found in each picture. Set four cardboard boxes around the room -- one with a red circle, one with a yellow square, one with a blue triangle and one with a green star. Blindfold each student, and then place an oven timer in one of the boxes. When the oven timer goes off, ask the child to remove the blindfold and identify which box has the oven timer by the box's shape and color.
Collect six plastic film canisters. Punch a hole in the lid of each canister. Put soap, potato chips, toothpaste, chewing gum, peanuts and coffee in the canisters. Using construction paper, cut out a red square, blue rectangle, yellow triangle, green circle, orange oval and purple star. Place the canisters on the color-shape papers. Have small pictures of soap, potato chips, toothpaste, chewing gum, peanuts and coffee cut out for each student. Each student also needs a sheet of paper with the red square, blue rectangle, yellow triangle, green circle, orange oval and purple star. Have the students smell each canister and place the appropriate picture in the appropriate color-shape on their paper.
