Blake chose to test different fruits and vegetables and see the amount of electricity each produced. We purchased an inexpensive volt meter and they went to town! His hypothesis was that the lemon would produce the most electricity. I was surprised by the results because I thought citrus would obviously be the highest due to its acidity.
The APPLE wins!
Here's his completed display board--
A panel of judges picks the best from each class to be in the "Science Fair," which basically meant it was on display this week for parents/students to come view during student-led conferences. Blake's made it into the Fair, but didn't win a ribbon. Still, pretty cool!
Brooklyn did something called swimming raisins. You mix vinegar + water with baking soda, then drop the raisins in. Bubbles collect around each raisin and then they float to the top. It was fun to watch! I think at one point, Matt even commented what a cool mom I was. ;) That was probably after the fourth VOLCANO we created, trying to do the dang experiment!!!!!!!

Bigger jar should work....
Nope.
Back to a small jar, trying to adjust ratios to avoid spillage, notice the table is still wet.
