If he is going to do if for a science exhibit, he really should use a
"blind" test, as Ode suggested. Perhaps he could code the plants and the
water, and have you do the watering, not knowing which is which.
Soon as I get hold of two identical plants, and figure out how to code
them, I'll be doing that--having my husband water them.
Otherwise, intent/belief will affect the results.

Hello Joy,
Can you tell me where you got the directions for the experiment? My
10 year old son is going to do this for his Science Fair Experiment.
I'd love to get a copy of the directions.
Thanks in advance.
