Sort objects: Place in four baskets a picture of a hand, a nose, an eye, and an ear. Collect a variety of objects with different characteristics. For example, one object might have a residual smell, another object might be crystalline that refracts light into colors; another might make sounds, and another might feel unusual to the touch. Some examples follow.
Smell: An empty perfume bottle, a garlic bud, a whole lemon, and cilantro;
Colors: A prism, crystals, a geode;
Sounds: Bells, triangle-and-striker, a drum, a bicycle horn
Feel: Corrugated paper, silk, sandpaper
As the children feel, smell, see or hear the objects they decide which sense they used to gather the most of the information they have about the object. This activity leads to the next one.
