Spencer participated in the 5th/6th grade science fair at his school. Dispite being pretty sick the week before, he was able to do a really good job. We all learned about batteries. It was pretty interesting. He made a battery out of a lemon. It wasn't strong enough to light a bulb, but he was able to test the volts with a multimeter. I didn't realize this, but no matter the size of the battery (AAA,AA,C or D) they all produce 1.5 volts of electricity. Interesting!!
