Any colorful piece of art stimulates a child's sense of sight. Give the child some bold tempura paint to draw a picture; hang the picture on a bulletin board or the fridge. Help the child create a simple mobile with glitter shapes or letters using construction paper, yarn and a plastic clothes hanger. Hang the art project from the ceiling so the child can view his creation daily. Staple some fabric pieces together to form a small book and have the child paint a "story" on them. She can "read" her own storybook over and over again.
Reinforce the sense of hearing by using crinkly paper to rip and paste into a collage. Various types of wrapping paper that are made from cellophane may also be used. Another art activity that involves sound is making a paper plate tambourine. Place a few beans or pieces of rice onto a paper plate and carefully glue or staple another plate over it. The child can shake the "tambourine" to hear the sound.
Consider adding sand to nontoxic, washable paint to add texture to any art project. Add feathers and low-grit sandpaper to art supplies for children to incorporate into a project. Finger painting is a way to create art through touch; another option is to have children press their thumbs on nontoxic, washable ink pads and then apply the prints onto pieces of paper or even clothing. Or give a child a cotton ball to use as a paintbrush and a blue piece of construction paper and encourage him to make a cloud painting with white paint.
Children can smell the art when using some tasty food items to create pictures. Use leftover pudding snack for finger paint or have children make a rainbow with colored fruit cereal circles. Create a scratch-and-sniff art piece by combining powdered drink mix with a few tablespoons of water to use for a "paint." Use a few different drink flavors to supply various colors. Just be aware that powdered drink mix can stain skin and clothing.
