Can you change the project to the effect of touch or wind on plants? Maybe sound, if it were loud enough
at the right frequency would shake the plants, but that might be bad for little eardrums. There is real
research on genes expressed when plants are touched (sprayed with water) by Janet Braam at Rice Univ.
in Houston. But that wouldn't make a very good demo for little kids unless they're *very* up on modern
biology. How about the sensitive plant, Mimosa pudica? It can be grown from seed if there's time.
Good luck,
