A game I first played at a baby shower is a fun sense-of-smell exercise. I put a pinch of several different spices on separate saucers and pass them around the room. The kids each sniff the spices and then try to guess what each one is called.
You can also blindfold your students and then have them taste different foods and describe them. The girls and I like to taste foods we haven't made and then try to guess what the ingredients are.
We also play “I smell something… ” Just like the “I see something… ” game.
