4th Grade Science Fair


This wonder woman (see the T-shirt) chose and designed her own experiment to see if the gasses emitted when you mix baking soda and vinegar, or lemon juice would blow up a balloon.  She tried a number of combinations including adding some different amounts of water to the acid + soda combo.

It worked!  kinda.

Her results were the best with a large amount of baking soda and vinegar.  Lemon juice didn't do as well, and adding water made it less effective, as well.

I love this girl.  She has such unique and independent interests.  Watching her grow is so rewarding for me.
