The Fruitcake's Electricity Experiment
First we lined up the test subjects by size order:
Then we used copper wires for the cathodes and zinc plated screws for the anodes inserting one of each into each piece of fruit.
Clip leads were used to connect each fruit to the volt meter.
We also ran a kitchen timer with lemon power.
We tried to run a small electric motor but found we did not have enough current.
Here are our findings:
1. Apple = 1.008 volts
2. Strawberry = 1.005 volts
3. Lemons = 0.993 volts
4. Tomato = 0.988 volts
5. Orange = 0.974 volts
6. Banana = 0.956 volts
7. Blueberry = 0.955 volts
8. Grape = 0.938 volts
9. Grapefruit = 0.974 volts
10. Potato = 0.794 volts
And here they are lined up in order of voltage:

Aug. 11, 2008 - Olympic Learning
The Olympics are off to a great start and this is the first year that the Summer games have held much importance to my ten year old. We gathered as a family on our big comfy couch and watched the opening ceremony. We set the DVR to record all the games and have dedicated the next two weeks to cheering on the American athletes. Along with watching the games, many questions get asked so we've been keeping a laptop close so we can quickly get the answers. (I love the internet!)
Just thought I'd share a couple of these Olympic links. ;-)
