Day 15

Balloons…

This year, as a fourth grader, Aubrey gets to participate in the school wide science fair. Aubrey and her partner Mada decided they wanted to test how the different kinds of earth/rock change the way a volcano reacts, or if it does.

So last night they had their procedures written, had all the items to test and we were off for a wet and wild night.

Aubrey was the one holding the balloon, while Mada timed everything and helped “push in the pin”. We used 3 different color water balloons, 3 without tape on them, 3 with 2 pieces of tape on them and 3 with 4 pieces of tape. (The original idea was to do 3 different balloons, but how one figures out how to put the “exact” amount of water into 3 different kinds of balloons, or heck how someone figures out how to put water inside Mylar is doing better than us – so we used tape!)

Here are a few shots of the girls, they need to now graph the results (pretty much that it does not matter AT ALL what the “outside materials are” if there’s a hole and even a little pressure that stuff is coming out, and FAST!) Work on their discussion’s and then post everything to their board to be ready to present in early Feb. (They both are really excited!)

It starts all happy and dry...
Up, there goes the first one....POP! (Aubrey was not really ready for that)
This one sprayed for a while...
The effect was neat...
Mada's got the watch...
Drip...
They all came bursting open, sooner or later...
This effect is soo neat, not sure HOW I got it so perfect...but it looks like the balloon has hair.
Pop goes the weasel
In goes another pin.
And another...
Last one, not to wet...

  2. These aren't just your average snapshots of your kids experiment. They tell a story in a beautiful way. The yellow balloon effect was sweet! It does look hairy :o) You caught the balloon pulling back while the water was still in the shape of the ballon. Sweet!
