I forgot to try the idea of taping contact paper, sticky side up onto one table to make a sensory station.

Program on the sense of smell for preschoolers:
The Human Body app allowed a child to drag something smelly to the nose. If it was a food item, the child could see the mouth salivate. I ended up doing this at the end of the program, since I was having technical difficulties during the program (with the new iOS).
The "smell" jars were small plastic, cylindrical containers from Big Lots. I had wanted to mash banana in one, have a cinnamon stick in another, a green pepper in the third, and a slice of orange in the fourth. I ended up putting small, solid perfume samples in them and covered with foil so one couldn't see what was inside. I poked holes in the top of the foil.
