any hot tub/Science Fair experiment ideas??!!

<< < (2/2)

Micah:
I got the perfect one for you.  It goes back to when I was about 15 working at a pool supply house. I was stacking chlorine and acid bottles.  A couple of the bottles still had some left inside.  So I thought I would pour everything into one bottle...
Next thing I know I'm looking up at one of my co-workers as he drags me away from the trailer.  Haz mat team came and evacuated 3 city blocks.  

Ingredients:
1 gal. liquid chlorine
1 gal muratic acid
= 2 gal of nasty mustard gas

P.S. hold your breath! ;D

Kervis,
My husband was a judge today in the Delaware Valley Science Fair.
He purposed the same idea as Vinny did. Have your daughter think up a question and then develop a hypothesis. For sixth grade you would probably have to limit the parameters. Maybe an example would be:
If I soaked in my hot tub for 1/2 hour and did not treat the tub with chlorine (sanitizer) it will become cloudy and unsafe for use in (1) day.
The experiment would be how long it takes the tub to show visible contamination without treatment. Using your Taylor tesk kit, you can measure the amount of chlorine present when the tub is perfectly clear and the amount when it begins to cloud.
Science teachers love when the child continues the experiment to answer the next question that would logically follow...in this case, like Vinny suggested, demonstrate how long it takes to clear up again and how much sanitizer was required.
Be sure to have her write her procedure in past tense. good luck, this sounds like fun! ;)
